LM101A/LH2101A
General Purpose Operational Amplifier
Features
* * * * * Input offset voltage 0.7 mV Input bias current 30 nA Input offset current 1.5 nA Full frequency compensation 30pF Supply voltage 5.0V to 20V
Description
The LM101A/LH2101A is a general purpose high performance operational amplifier fabricated monolithically on a silicon chip by an advanced epitaxial process. The LH2101A consists of two LM101A ICs in one 16-lead DIP. The units may be fully compensated with the addition of a 30 pF capacitor stabilizing the circuit for all feedback configurations including capacitive loads. The device may be operated as a comparator with a differential input as high as 30V. Used as a comparator the output can be clamped at any desired level to make it compatible with logic circuits. The LM101A and LH2101A operate over the full military temperature range from -55C to +125C.

Precision Operational Amplifiers
Features
* * * * * * * * * Low input bias current -- 2 nA Low input offset current -- 200 pA Low input offset voltage -- 500mV Low input offset drift -- 5 mV/C Wide supply range -- 3V to 20V Low supply current -- 0.6 mA High PSRR -- 96 dB High CMRR -- 96 dB MIL-STD-883B available
Description
The LM108A operational amplifiers features low input bias current combined with the advantages of bipolar transistor construction; input offset voltages and currents are kept low over a wide range of temperature and supply voltage. Fairchild Semiconductor's superbeta bipolar manufacturing process includes extra treatment at epitaxial growth to ensure low input voltage noise. The LH2108 consists of two LM108 ICs in one 16-lead DIP. The "A" versions meet tighter electrical specifications than the plain versions. All types are available with 883B military screening.

Typical Applications
The LM108 series has very low input offset and bias currents; the user is cautioned that printed circuit board leakages can produce significant errors especially at high board temperatures. Careful attention to board layout and
cleaning procedure is required to achieve the LM108A's rated performance. It is suggested that board leakage be minimized by encircling the input pins with a guard ring maintained at a potential close to that of the inputs. The guard ring should be driven by a low impedance source such as an amplifier's output or ground.

LM124/LM324
Single-Supply Quad Operational Amplifier
Features
* * * * * * Large DC voltage gain--100 dB Compatible with all forms of logic Temperature compensated Unity Gain Bandwidth--1 MHz Large output voltage swing--0V to (+VS -1.5V) Input common mode voltage range includes ground
Description
Each of the devices in this series consists of four independent high-gain operational amplifiers that are designed for single-supply operation. Operation from split power supplies is also possible and the low power supply drain is independent of the magnitude of the power supply voltage. Used with a dual supply, the circuit will operate over a wide range of supply voltages. However, a large amount of crossover distortion may occur with loads to ground. An external current-sinking resistor to -VS will reduce crossover distortion. There is no crossover distortion problem in single-supply operation if the load is direct-coupled to ground.

Notes: 1. Short circuits from the output to +VS can cause excessive heating and eventual destruction. The maximum output current is approximately 40 mA independent of the magnitude of +VS. At values of supply voltage in excess d +VS, continuous short circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers. 2. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to the +VS voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage again returns to a value greater than 0.3V.

Notes: 1. VOUT = 1.4V, RS = 0W with +VS from 5V to 30V; and over the full common mode range (0V to +VS-1.5V). 2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. 3. The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common mode voltage range is +VS-1.5V, but either or both inputs can go to +32V without damage. 4. Due to proximity of external components, ensure that coupling is not originating via stray capacitance between these externall parts. This typically can be detected as this type of capacitance increases at higher frequencies.

LM139/LM139A, LM339
Single Supply Quad Comparators
Features
* Input common mode voltage range includes ground * Wide single supply voltage range--2V to 36V * Output compatible with TTL, DTL, ECL, MOS and CMOS logic systems * Very low supply current drain (0.8 mA) independent of supply voltage
Description
These devices offer higher frequency operation and faster switching than can be had from internally compensated quad op amps. Intended for single supply applications, the Darlington PNP input stage allows them to compare voltages that include ground. The two stage common-emitter output circuit provides gain and output sink capacity of 3.2 mA at an output level of 400 mV. The output collector is left open, permitting the designer to drive devices in the range of 2V to 36V. They are intended for applications not needing response time less than 1 ms, but demanding excellent op amp input parameters to offset voltage, current and bias current, to ensure accurate comparison with a reference voltage.

Notes: 1. Short circuits from the output to +VS can cause excessive heating and eventual destruction. The maximum output current is approximately 20 mA independent of the magnitude of +Vs. 2. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output voltage of the comparators to go to the +VS voltage level (or to ground for a large overdrive) for the time duration that an input is driven negative. This is not destructive and nominal output states will re-establish when the input voltage, which was negative, again returns to a value greater than -0.3V.

At output switch points VOUT = 1.4V, RS = 0W with +VS from 5V to 30V; and over the full input common mode range (VOUT to +VS-1.5V). 3. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the reference or input lines. 4. The input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common mode voltage range is +VS-1.5V, but either or both inputs can go to +30V without damage. 5. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained. See Typical Performance Characteristics section. 6. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common mode range, the comparator will provide a proper output state. The low input voltage stage must not be less than -0.3V (or 0.3V below the magnitude of the negative power supply, if used). 7. Guaranteed by design.

Low Power Quad 741 Operational Amplifier
Features
* * * * * * * * * * 741 op amp operating characteristics Low supply current drain--0.6 mA/amplifier Class AB output stage--no crossover distortion Pin compatible with the LM124 Low input offset voltage--1.0 mV Low input offset current--4.0 nA Low input bias current--30 nA Unity gain bandwidth--1.0 MHz Channel Separation--120 dB Input and output overload protection
Description
The LM148 is a true quad 741. It consists of four independent high-gain, internally compensated, low-power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar 741 operational amplifier. In addition, the total supply current for all four amplifiers is comparable to the supply current of a single 741 type op amp. Other features include input offset currents and input bias currents which are much less than those of a standard 741. Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling. The LM148 can be used anywhere multiple 741 type amplifiers are being used and in applications where amplifier matching or high packing density is required.

Applications Discussion
The LM148 low power quad operational amplifier exhibits performance comparable to the popular 741. Substitution can therefore be made with no change in circuit behavior. The input characteristics of these devices allow differential voltages which exceed the supplies. Output phase will be correct as long as one of the inputs is within the operating common mode range. If both exceed the negative limit, the output will latch positive. Current limiting resistors should be used on the inputs in case voltages become excessive. When capacitive loading becomes much greater than 100pF, a resistor should be placed between the output and feedback connection in order to reduce phase shift.
The LM148 is short circuit protected to ground and supplies continuously when only one of the four amplifiers is shorted. If multiple shorts occur simultaneously, the unit can be destroyed due to excessive power dissipation. To assure stability and to minimize pickup, feedback resistors should be placed close to the input to maximize the feedback pole frequency (a function of input to ground capacitance). A good rule of thumb is that the feedback pole frequency should be 6 times the operating -3.0B frequency. If less, a lead capacitor should be placed between the output and input.

Description
The LM1851 is a controller for AC outlet ground fault interrupters. These devices detect hazardous grounding conditions (example: a pool of water and electrical equipment connected to opposite phases of the AC line) in consumer and industrial environments. The output of the IC triggers an external SCR, which in turn opens a relay circuit breaker to prevent a harmful or lethal shock. Full advantage of the U.S. UL943 timing specification is taken to ensure maximum immunity to false triggering due to line noise. A special feature is found in circuitry that rapidly resets the integrating timing capacitor in the event that noise pulses introduce unwanted charging currents. Also, flip-flop is included that ensures firing of even a slow circuit breaker relay on either half-cycle of the line voltage when external full wave rectification is used. The application circuit can be configured to detect both normal faults (hot wire to ground) and grounded neutral faults.

Functional Description
The voltage at the supply pin is clamped to +26V by the internal shunt regulator D3. This shunt regulator also generates an artificial ground voltage for the noninverting input of A1 (shown as a +10V source). A1, Q1, and Q2 act a a current mirror for fault current signals (which are derived from an external transformer). When a fault signal is present, the mirrored current charges the external timing capacitor until its voltage exceeds the latch trigger threshold (typically 17.5V). When then this threshold is exceeded, the latch engages and Q3 turns off, allowing I2 to drive the SCR connected to pin 1. Extra Circuitry in the feedback path of A1 works with the switched current source I1 to remove any charge on CT induced by noise in the transformer. If no fault current is
present, then I1 discharges CT with a current equal to 3 ITH, where ITH is the value of current set by the external RSET resistor. If fault signals are present at the input of A1 (which is held at virtual ground, +10V), one of the two current mirrors in the feedback path of A1 (Q4 and Q5) will become active, depending on which half-cycle the fault occurs. This action will raise the voltage at VS, switching I1 to a value equal to ITH, and reducing the discharge rate of CT to better allow fault currents to charge it. Notice that ITH discharges CT during both half-cycles of the line, while IF only charges CT during the half-cycle in which IF exits pin 2 (since Q1 will only carry fault current in one direction). Thus, during one half-cycle, IF-ITH charges CT, while during the other half-cycle ITH discharges it.

Applications Discussion
A typical ground fault interrupter circuit is shown in Figure 10. It is designed to operate on 120 VAC line voltage with 5 mA normal fault sensitivity. A full-wave rectifier bridge and a 15k/2W resistor are used to supply the dc power required by the IC. A 1 mF capacitor at pin 8 is used to filter the ripple of the supply voltage and is also connected across the SCR to allow firing of the SCR on either half-cycle. When a fault causes the SCR to trigger, the circuit breaker is energized and line voltage is removed from the load. At this time no fault current flows and the CT discharge current increases from ITH to 3ITH (see Block Diagram). This quickly resets both the timing capacitor and the output latch. The circuit breaker can be reset and the line voltage again supplied to the load, assuming the fault has been removed. A 1000:1 sense transformer is used to detect the normal fault. The fault current, which is basically the difference current between the got and neutral lines, is stepped down by 1000 and fed into the input pin of the operational amplifier through a 10 mF capacitor. The 0.0033 mF capacitor between pin 2 and pin 3 and the 200 pF between pins 3 and 4 are added to obtain better noise immunity. The normal fault sensitivity is determined by the timing capacitor discharging current, ITH. ITH can be calculated by: 7V I TH = ------------ 2 R SET (1)
The correct value for RSET can also be determined from the characteristic curve that plots equation (3). Note that this is an approximate calculation; the exact value of RSET depends on the specific sense transformer used and LM1851 tolerances. Inasmuch as UL943 specifies a sensitivity "window" of 4 mA to 6mA, provision should be made to adjust RSET with a potentiometer. Independent of setting sensitivity, the desired integration time can be obtained through proper selection of the timing capacitor, CT. Due to the large number of variables involved, proper selection of CT is best done empirically. The following design example should only be used as a guideline. Assume the goal is to meet UL943 timing requirements. Also assume that worst case timing occurs during GFI startup (S1 closure) with both a heavy normal fault and a 2W grounded neutral fault present. This situation is shown diagrammatically in Figure 8.
S1 Hot Line Neutral GFI Neutral RN 0.4 RB 500 I RB 500 (0.2)I Hot
(0.8)I
At the decision point, the average fault current just equals the threshold current, ITH. I F ( rms ) I TH = ------------------- 0.91 2 (2)
65-1851-12
Figure 8.
Where IF(rms) is the rms input fault current to the operational amplifier and the factor of 2 is due to the fact that IF charges the timing capacitor only during one half-cycle, while ITH discharges the capacitor continuously. The factor 0.91 converts the rms value to an average value. Combining equations (1) and (2) we have: 7V R SET = ----------------------------------I F ( rms ) 0.91 (3)
UL943 specifies 25 ms average trip time under these conditions. Calculation of CT based upon charging currents due to normal fault only is as follows: 1. Start with a 25 ms specification. Subtract 3 ms GFI turn-on time (15k and 1 mF). Subtract 8 ms potential loss of one half-cycle due to fault current sense of halfcycles only. Subtract 4 ms time required to open a sluggish circuit breaker. This gives a total 10 ms maximum integration time that could be allowed. To generate 8 ms value of integration time that accommodates component tolerances and other variables: 1T C T = -----------V (5)
2. 3. 4.
For example, to obtain 5 mA(rms) sensitivity for the circuit in Figure 7 we have: 7V R SET = ----------------------------- = 1.5MW 5 mA 0.91 ----------------------------1000 (4)

In practice, the actual value of CT will have to be modified to include the effects of the neutral loop upon the net charging current. The effect of neutral loop induced currents is difficult to quantize, but typically they sum with normal fault currents, thus allowing a larger value of CT. For UL943 requirements, 0.015 mF has been found to be the best compromise between timing and noise. For those GFI standards not requiring grounded neutral detection, a still larger value capacity can be used and better noise immunity obtained. The larger capacitor can be accommodated because RN and RG are not present, allowing the full fault current, I, to enter the GFI. In Figure 10, grounded neutral detection is accomplished by feeding the neutral coil with 120 Hz energy continuously and allowing some of the energy to couple into the sense transformer during conditions of neutral fault. Transformers may be obtained from Magnetic Metals, Inc., 21st Street and Hayes Street, Camden, NJ 08101-- (609) 964-7842.

Addressing Logic
The register addressing logic is composed of two blocks of logic The first is the address register and counter (ADDRCNTR) and the second is the address decode (ADDRDEC) ADDRCNTR LOGIC Addresses for the data registers can be generated by one of two methods Manual addressing requires that each byte of each register that needs to be loaded needs to be addressed To load both bytes of all 19 registers would require a total of 57 load cycles (19 address and 38 data cycles) Auto Addressing requires that only the initial register value be specified The Auto Load sequence would require only 39 load cycles to completely program all registers (1 address and 38 data cycles) In the auto load sequence the low order byte of the data register will be written first followed by the high order byte on the next load cycle At the time the High Byte is written the address counter is incremented by 1 The counter has been implemented to loop on the initial value loaded into the address register For example If a value of 0 was written into the address register then the counter would count from 0 to 18 before resetting back to 0 If a value of 15 was written into the address register then the counter would count from 15 to 18 before looping back to 15 If a value greater than or equal to 18 is placed into the address register the counter will continuously loop on this value Auto addressing is initiated on the falling edge of LOAD when ADDRDATA is 0 and LHBYTE is 1 Incrementing and loading of data registers will not commence until the falling edge of LOAD after ADDRDATA goes to 1 The next rising edge of LOAD will load the first byte of data Auto Incrementing is disabled on the falling edge of LOAD after ADDRDATA and LHBYTE goes low

Addressing Logic (Continued)
ADDRDEC LOGIC The ADDRDEC logic decodes the current address and generates the enable signal for the appropriate register The enable values for the registers and counters change on the falling edge of LOAD Two types of ADDRDEC logic is enabled by 2 pair of addresses Addresses 22 or 54 (Vectored Restart logic) and Addresses 23 or 55 (Vectored Clear logic) Loading these addresses will enable the appropriate logic and put the part into either a Restart (all counter registers are reinitialized with preprogrammed data) or Clear (all registers are cleared to zero) state Reloading the same ADDRDEC address will not cause any change in the state of the part The outputs during these states are frozen and the internal CLOCK is disabled Clocking the part during a Vectored Restart or Vectored Clear state will have no effect on the part To resume operation in the new state or disable the Vectored Restart or Vectored Clear state another nonADDRDEC address must be loaded Operation will begin in the new state on the rising edge of the non-ADDRDEC load pulse It is recommended that an unused address be loaded following an ADDRDEC operation to prevent data registers from accidentally being corrupted The following Addresses are used by the device Address 0 Status Register REG0 Address 1-18 Data Registers REG1-REG18 Address 19-21 Unused Address 22 54 Restart Vector (Restarts Device) Address 23 55 Clear Vector (Zeros All Registers) Address 24-31 Unused Address 32-50 Register Scan Addresses Address 51-53 Counter Scan Addresses Address 56-63 Unused At any given time only one register at most is selected It is possible to have no registers selected VECTORED RESTART ADDRESS The function of addresses 22 (16H) or 54 (36H) are similar to that of the CLR pin except that the preprogramming of the registers is not affected It is recommended but not required that this address is read after the initial device configuration load sequence A 1 on the ADDRDATA pin (Auto Addressing Mode) will not cause this address to automatically increment The address will loop back onto itself regardless of the state of ADDRDATA unless the address on the Data inputs has been changed with ADDRDATA at 0 VECTORED CLEAR ADDRESS Addresses 23 (17H) or 55 (37H) is used to clear all registers to zero simultaneously This function may be desirable to use prior to loading new data into the Data or Status Registers This address is read into the device in a similar fashion as all of the other registers A 1 on the ADDRDATA pin (Auto Addressing Mode) will not cause this address to automatically increment The address will loop back onto itself regardless of the state of ADDRDATA unless the address on the Data inputs has been changed with ADDRDATA at 0

FIGURE 3 ADDRDEC Timing GEN LOCKING The 'ACT715 LM1882 and 'ACT715-R LM1882-R is designed for master SYNC and BLANK signal generation However the devices can be synchronized (slaved) to an external timing signal in a limited sense Using Vectored Restart the user can reset the counting sequence to a given location the beginning at a given time the rising edge of the LOAD that removes Vector Restart At this time the next CLOCK pulse will be CLOCK 1 and the count will restart at the beginning of the first odd line Preconditioning the part during normal operation before the desired synchronizing pulse is necesasry However since LOAD and CLOCK are asynchronous and independent this is possible without interruption or data and performance corruption If the defaulted 14 31818 MHz RS-170 values are being used preconditioning and restarting can be minimized by using the CLEAR pulse instead of the Vectored Restart operation The 'ACT715-R LM1882-R is better suited for this application because it eliminates the need to program a 1 into Bit 10 of the Status Register to enable the CLOCK Gen Locking to another count location other than the very beginning or separate horizontal vertical resetting is not possible with the 'ACT715 LM1882 nor the 'ACT715-R LM1882-R SCAN MODE LOGIC A scan mode is available in the ACT715 LM1882 that allows the user to non-destructively verify the contents of the registers Scan mode is invoked through reading a scan address into the address register The scan address of a given register is defined by the Data register address a 32 The internal Clocking signal is disabled when a scan address is read Disabling the clock freezes the device in it's present state Data can then be serially scanned out of the data registers through the ODD EVEN Pin The LSB will be scanned out first Since each register is 12 bits wide completely scanning out data of the addressed register will require 12 CLOCK pulses More than 12 CLOCK pulses on the same register will only cause the MSB to repeat on the output Re-scanning the same register will require that register to be reloaded The value of the two horizontal counters and 1 vertical counter can also be scanned out by using address numbers 51 - 53 Note that before the part will scan out the data the LOAD signal must be brought back HIGH

Additional Applications Information
POWERING UP The 'ACT715 LM1882 default value for Bit 10 of the Status Register is 0 This means that when the CLEAR pulse is applied and the registers are initialized by loading the default values the CLOCK is disabled Before operation can begin Bit 10 must be changed to a 1 to enable CLOCK If the default values are needed (no other programming is required) then Figure 5 illustrates a hardwired solution to facilitate the enabling of the CLOCK after power-up Should control signals be difficult to obtain Figure 6 illustrates a possible solution to automatically enable the CLOCK upon power-up Use of the 'ACT715-R LM1882-R eliminates the need for most of this circuitry Modifications of the Figure 6 circuit can be made to obtain the lone CLEAR pulse still needed upon power-up Note that although during a Vectored Restart none of the preprogrammed registers are affected some signals are affected for the duration of one frame only These signals are the Horizontal and Vertical Drive signals After a Vectored Restart the beginning of these signals will occur at the first CLK The end of the signals will occur as programmed At the completion of the first frame the signals will resume to their programmed start and end time PREPROGRAMMING ``ON-THE-FLY'' Although the 'ACT715 LM1882 and 'ACT715-R LM1882-R are completely programmable certain limitations must be set as to when and how the parts can be reprogrammed Care must be taken when reprogramming any End Time registers to a new value that is lower than the current value Should the reprogramming occur when the counters are at a count after the new value but before the old value then the counters will continue to count up to 4096 before rolling over For this reason one of the following two precautions are recommended when reprogramming ``on-the-fly'' The first recommendation is to reprogram horizontal values during the horizontal blank interval only and or vertical values during the vertical blank interval only Since this would require delicate timing requirements the second recommendation may be more appropriate The second recommendation is to program a Vectored Restart as the final step of reprogramming This will ensure that all registers are set to the newly programmed values and that all counters restart at the first CLK position This will avoid overrunning the counter end times and will maintain the video integrity

14 DIP The LM224 series consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide voltage range. Operation from split power supplies is also possible so long as the difference between the two supplies is 3 volts to 32 volts. Application areas include transducer amplifier, DC gain blocks and all the conventional OP amp circuits which now can be easily implemented in single power supply systems.

PROGRAMMABLE SHUNT REGULATOR
The LM336-2.5/B integrated Circuits are precision 2.5V shunt regulators. The monolithic IC voltage references operates as a low temperature coefficient 2.5V zener with 0.2 dynamic impedance. A third terminal on the KA336-2.5/B allow the reference voltage and temperature coefficient to be trimmed easily. LM3362.5/B are useful as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry. The 2.5V make it convenient to obtain a stable reference from low voltage supplies. Further, since the LM336-2.5/B operate as shunt regulators, they can be used as either a positive or negative voltage reference. TO-92

QUAD OPERATIONAL AMPLIFIER
QUAD OPERATIONAL AMPLIFIERS
The LM248/LM348 is a true quad LM741. It consists of four independent, high-gain, internally compensated, low-power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar LM741 operational amplifier. In addition the total supply current for all four amplifiers is comparable to the Supply current of a single LM741 type OP Amp. Other features include input offset currents and input bias current which are much less than those of a standard LM741. Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling. 14 DIP

DUAL OPERATIONAL AMPLIFIER
DUAL OPERATIONAL AMPLIFIERS
8 DIP The LM258 series consists of four independent, high gain, internally Frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage. Operation from split power supplies is also possible and the low power Supply current drain is independent of the magnitude of the power Supply voltage. Application areas include transducer amplifier, DC gain blocks and all the conventional OP amp circuits which now can be easily implemented in single 8 SOP power supply system.
FEATURES
* Internally frequency compensated for unity gain * Large DC voltage gain: 100dB * Wide power supply range: LM258/A, LM358/A: 3V~32V (or 1.5V~16V) LM2904: 3V~26V (or 1.5V~13V) * Input common-mode voltage range Includes ground * Large output voltage swing: 0V DC to Vcc - 1.5V DC * Power drain suitable for battery operation. 9 SIP

1. Supply current when output is high is typically 1mA less at VCC = 5V 2. Tested at VCC = 5.0V and VCC = 15V 3. This will determine maximum value of RA + RB for 15V operation, the max. total R = 20M, and for 5V operation the max. total R = 6.7M
APPLICATION CIRCUIT
LM555/I
APPLICATION NOTE
SINGLE TIMER
The application circuit shows astable mode. Pin 6 (threshold) is tied to Pin 2 (trigger) and Pin 4 (reset) is tied to VCC (Pin 8). The external capacitor C1 of Pin 6 and Pin 2 charges through RA, RB and discharges through RB only. In the internal circuit of the LM555 one input of the upper comparator is the 2/3 VCC (R1 =R2=R3, another input if it If it is connected Pin 6. As soon as charging C1 is higher than 2/3 Vcc, discharge transistor Q1 turns on and C1 discharges to collector of transistor Q1. Therefore, the flip-flop circuit is reset and output is low. One input of lower comparator is the 1/3 VCC, discharge transistor Q1 turn off and C1 charges through RA and RB. Therefore, the flip-flop circuit is set and output is high. So to say, when C1 charges through RA and R1 output is high and when C1 discharges through RB output is low. The charge time (output is high) T1 is 0.693 (RA+RB) C1 and the discharge time (output is low) T2 is 0.693 (RB C1). (In VCC-1/3VCC = 0.693) VCC-2/3VCC Thus the total period time T is given by T=T1 +T2 = 0.693 (RA +2RB) C1. Then the frequency of astable mode is given by f= =1 T 1.44 (RA + 2RB)C1
The duty cycle is given by D.C = T =2 T RB RA + 2RB
If you make use of the LM556 you can make two astable modes.

The LM555 can free run as a mulitivibrator by triggering itself; refer to Fig.2. The output can swing from VDD to GND and have 50 duty cycle square wave. Less than 1% frequency deviation can be observed, over a voltage range of 2 to 5V. f-1/1.4RC

Monostable Operation
The LM555 can be used as a one-short, i.e. monostable multivibrator. Initially, because the inside discharge transistor is on state, external timing capacitor is held to GND potential. Upon application of a negative TRIGGER pulse pin 2, the intern discharge transistor is off state and the voltage across the capacitor increases with time constant T = RAC and OUTPUT goes to high state. When the voltage across the capacitor equals 2/3VCC the inner comparator is reset by THRESHOLD input and the discharge transistor goes to on state, which in turn discharges the capacitor rapidly and drives the OUTPUT to its low state.

LM78XX (KA78XX, MC78XX) FIXED VOLTAGE REGULATOR (POSITIVE)
3-TERMINAL 1A POSITIVE VOLTAGE REGULATORS
The LM78XX series of three-terminal positive regulators are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

TYPICAL APPLICATIONS
Design Considerations The MC79LXXA Series of fixed voltage regulators are designed with Thermal Overload Protection that shuts down the circuit when subjected to an excessive power overload condition. Internal Short-Circuit Protection that limits the maximum current the circuit will pass. In many low current applications, compensation capacitors are not required. However, it is recommended that the regulator input be bypassed with a capacitor if the regulator is connected to the power supply filter with long wire lengths, or if the output load capacitance is large. An input bypass Fig. 1 Positive And Negative Regulator
FIXED VOLTAGE REGULATOR (NEGATIVE)
capacitor should be selected to provide good high frequency characteristics to insure stable operation under all load conditions. A 0.33F or larger tantalum, mylar, or other capacitor having low internal impedance at high frequencies should be chosen. The bypass capacitor should be mounted with the shortest possible leads directly across the regulator's input terminals. Normally good construction techniques should be used to minimize ground loops and lead resistance drops since the regulator has no external sense lead. Bypassing the output is also recommended. Fig. 2 Typical Application
OUTPUT
A common ground is required between the Input and the output voltages. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input ripple voltage.
= C1 is required if regulator is located an appreciable distance from power supply filter. * * = CO improves stability and transient response.

LM79MXX
FIXED VOLTAGE REGULATOR(NEGATIVE)
TYPICAL APPLICATIONS
Bypass capacitors are recommended for stable operation of the KA79MXX series of regulators over the input voltage and output current ranges. Output bypass capacitors will improve the transient response of the regulator. The bypass capacitors, (2F on the input, 1F on the output) should be ceramic or solid tantalum which have good high frequency characteristics. If aluminum electronics are used, their values should be 10F or larger. The bypass capacitors should be mounted with the shortest leads, and if possible, directly across the regulator terminals. Fig. 1 Fixed Output Regulator
Fig. 2 Variable Output Note 1. Required for stability. For value given, capacitor must be solid tantalum. 25F aluminum electrolytic may be substituted. 2. C2 improves transient response and ripple rejection. Do not increase beyond 50F.
