Schematic
HCPL-5760/1/K

Each unit contains a light emitting diode (LED), a threshold sensing input buffer IC, and a high gain photon detector to provide an optocoupler which permits adjustable external threshold levels. The input buffer circuit has a nominal turn on threshold of 2.5 mA (ITH+) and 3.6 volts (VTH+). The addition of one or more external attenuation resistors permits the use of this device over a wide range of input voltages and currents. Threshold sensing prior to the LED and detector elements minimizes effects of any variation in optical
coupling. Hysteresis is also provided in the buffer for extra noise immunity and switching stability. The buffer circuit is designed with internal clamping diodes to protect the circuitry and LED from a wide range of over-voltage and over-current transients while the diode bridge enables easy use with ac voltage input. These units combine several unique functions in a single package, providing the user with an ideal component for computer
input boards and other applications where a predetermined input threshold optocoupler level is desirable. The high gain output stage features an open collector output providing both TTL compatible saturation voltages and CMOS compatible breakdown voltages. This is an eight pin DIP which may be purchased with a variety of lead bend and plating options. See Selection Guide Table for details. Standard Microcircuit Drawing (SMD) parts are available for each lead style.

Notes: 1. Maximum operating frequency is defined when output waveform (Pin 6) attains only 90% of VCC with RL = 1.8 k, CL = 15 pF using a 5 V square wave input signal. 2. Measured at a point 1.6 mm below seating plane. 3. Current into/out of any single lead. 4. Surge input current duration is 3 ms at 120 Hz pulse repetition rate. Transient input current duration is 10 s at 120 Hz pulse repetition rate. Note that maximum input power, PIN, must be observed. 5. Derate linearly above 100C free-air temperature at a rate of 4.26 mW/C. Maximum input power dissipation of 195 mW allows an input IC junction temperature of 150C at an ambient temperature of TA = 125C with a typical thermal resistance from junction to ambient of JAi = 235C/W. The typical thermal resistance from junction to case is equal to 170C/W. Excessive PIN and TJ may result in device degradation. 6. The 1.8 k load represents 1 TTL unit load of 1.6 mA and the 4.7 k pull-up resistor.
7. Logic low output level at Pin 6 occurs under the conditions of VIN VTH+ as well as the range of VIN > VTH - once VIN has exceeded VTH+. Logic high output level at Pin 6 occurs under the conditions of VIN VTH- as well as the range of VIN < VTH+ once VIN has decreased below VTH-. 8. The ac voltage is instantaneous voltage. 9. Device considered a two terminal device: Pins 1, 2, 3, 4 connected together, Pins 5, 6, 7 8 connected together. 10. This is a momentary withstand test, not an operating condition. 11. The tPHL propagation delay is measured from the 2.5 V level of the leading edge of a 5.0 V input pulse (1 s rise time) to the 1.5 V level on the leading edge of the output pulse (see Figure 7). 12. The tPLH propagation delay is measured from the 2.5 V level of the trailing edge of a 5.0 V input pulse (1 s fall time) to the 1.5 V level on the trailing edge of the output pulse (see Figure 7). 13. Common mode transient immunity in Logic High level is the maximum tolerable dVCM/dt of the common mode
voltage, VCM, to ensure that the output will remain in a Logic High state (i.e., VO > 2.0 V). Common mode transient immunity in Logic Low level is the maximum tolerable dVCM/dt of the common mode voltage, VCM, to ensure that the output will remain in a Logic Low state (i.e., VO < 0.8 V). See Figure 8. 14. In applications where dVCM/dt may exceed 50,000 V/s (such as static discharge), a series resistor, RCC, should be included to protect the detector IC from destructively high surge currents. The recommended value for RCC is 240 per volt of allowable drop in VCC (between Pin 8 and VCC) with a minimum value of 240 . 15. D1 and D2 are Schottky diodes; D3 and D4 are zener diodes. 16. Standard parts receive 100% testing at 25C (Subgroups 1 and 9). SMD, Class H and Class K parts receive 100% testing at 25, 125, and -55C (Subgroups 1 and 9, 2 and 10 ,3 and 11, respectively.) 17. Parameters shall be tested as part of device initial characterization and after process changes. Parameters shall be guaranteed to the limits specified for all lots not specifically tested.

Electrical Considerations
The HCPL-5760, HCPL-5761, HCPL-576K or 5962-89477 optocoupler has internal temperature compensated, predictable voltage and current threshold points which allow selection of an external resistor, Rx, to determine larger external threshold voltage levels. For a desired external threshold voltage, V , a corresponding typical value of Rx can be obtained from Figure 10. Specific calculation of Rx can be obtained from Equation (1) of Figure 11. Specification of both V+ and Vvoltage threshold levels simultaneously can be obtained by the use of Rx and Rp as shown in Figure 11 and determined by Equations (2) and (3). Rx can provide over-current transient protection by limiting input current during a transient condition. For monitoring contacts with a relay or switch, the HCPL-5760/1/K, or 5962-89477 combination with Rx and Rp can be used to allow a specific current to be conducted through the contacts for cleaning purposes (wetting current). The choice of which input voltage clamp level to choose depends upon the application of this device (see Figure 3). It is recommended that the low clamp condition be used when possible to lower the input power dissipation as well as the LED current, which minimizes LED degradation over time. In applications where dVCM/dt may be extremely large (such as static discharge), a series resistor, RCC, should be connected in series with VCC and Pin 8 to protect the

detector IC from destructively high surge currents. See note 14 for determination of RCC. In addition, it is recommended that a ceramic disc bypass capacitor of 0.01 F to 0.1 F be placed between Pins 8 and 5 to reduce the effect of power supply noise. For interfacing ac signals to TTL systems, output low pass filtering can be performed with a pullup resistor of 1.5 k and 20 F capacitor. This application requires a Schmitt trigger gate to avoid slow rise time chatter problems. For ac input applications, a filter capacitor can be placed across the dc input terminals for either signal or transient filtering. Either ac (Pins 1, 4) or dc (Pins 2, 3) input can be used to determine external threshold levels. For one specifically selected external threshold voltage level V+ or V-, Rx can be determined without use of Rp via V+ - VTH+ (-) (-) Rx = --------- (1) ITH+ (-)
Figure 10. Typical External Threshold Characteristic, V vs. Rx.
For two specifically selected external threshold voltage levels, V+ and V-, the use of Rx and Rp will permit this selection via equations (2), (3) provided the following conditions are met:
V+ VTH+ V+ - VTH+ ITH+ --- --- and -------- < ---- V- VTHV- - VTHITHVTH- (V+) - VTH+ (V-) Rx = -------------------- (2) ITH+ (VTH-) - ITH- (VTH+) RP = VTH- (V+) - VTH+ (V-) --------------------------- (3) ITH+ (V- - VTH-) + ITH- (VTH+ - V+) See Application Note 1004 for more information.
