GENERAL DESCRIPTION
The SW06 is a four channel single-pole, single-throw analog switch that employs both bipolar and ion-implanted FET devices. The SW06 FET switches use bipolar digital logic inputs which are more resistant to static electricity than CMOS devices. Ruggedness and reliability are inherent in the SW06 design and construction technology. Increased reliability is complemented by excellent electrical specifications. Potential error sources are reduced by minimizing "ON" resistance and controlling leakage currents at high temperatures. The switching FET exhibits minimal RON variation over a 20 V analog signal range and with power supply voltage changes. Operation from a single positive power supply voltage is possible. With V+ = 36 V, V- = 0 V, the analog signal range will extend from ground to +32 V. PNP logic inputs are TTL and CMOS compatible to allow the SW06 to upgrade existing designs. The logic "0" and logic "1" input currents are at microampere levels reducing loading on CMOS and TTL logic.

NOTE
These single-supply-operation characteristic curves are valid when the negative power supply V- is tied to the logic ground reference pin "GND." TTL input compatibility is still maintained when "GND" is the same potential as the TTL ground. tOFF is measured from 50% of logic input waveform to 0.9 VO. The analog voltage range extends from 0 V to V+ -4 V; the switch will no longer respond to logic control when VA is within 4 volts of V+.

Figure 1. Functional Applications of SW06
APPLICATIONS INFORMATION
The single analog switch product configures, by appropriate pin connections, into four switch applications. As shown in Figure 1, the SW06 connects as a QUAD SPST, a DUAL SPDT, a DUAL DPST, or a DPDT analog switch. This versatility increases further when taking advantage of the disable input (DIS) which turns all switches OFF when taken active low. Ion-implantation of the JFET analog switch achieves low ON resistance and tight channel-to-channel matching. Combining the low ON resistance and low leakage currents results in a worst case voltage error figure VERROR @ +125C = ID(ON) x RSD(ON) = 100 nA x 100 = 11 microvolts. This amount of error is negligible considering dissimilar-metal thermally-induced offsets will be in the 5 to 15 microvolt range.
LOGIC INPUTS
supplies are OFF. When the V+ and V- supplies are OFF, the logic inputs present a reverse bias diode loading to active logic inputs. Input logic thresholds are independent of V+ and V- supplies making single V+ supply operation possible by simply connecting GND and V- together to the logic ground supply.
ANALOG VOLTAGE AND CURRENT
ANALOG VOLTAGE
The logic inputs (INX) and disable input (DIS) are referenced to a TTL logic threshold value of two forward diode drops (1.4 V at +25C) above the GND terminal. These inputs use PNP transistors which draw maximum current at a logic "0" level and drops to a leakage current of a reverse biased diode as the logic input voltage raises above 1.4 volts. Any logic input voltage greater than 2.0 volts becomes logic "1," less than 0.8 volts becomes logic "0" resulting in full TTL noise immunity not available from similar CMOS input analog switches. The PNP transistor inputs require such low input current that the SW06 approaches fan-ins of CMOS input devices. These bipolar logic inputs exceed any CMOS input circuit in resistance to static voltage and radiation susceptibility. No damage will occur to the SW06 if logic high voltages are present when the SW06 power
These switches have constant ON resistance for analog voltages from the negative power supply (V-) to within 4 volts of the positive power supply. This characteristic shown in the plots results in good total harmonic distortion, especially when compared to CMOS analog switches that have a 20 to 30 percent variation in ON resistance versus analog voltage. Positive analog input voltage should be restricted to 4 volts less than V+ assuring the switch remains open circuit in the OFF state. No increase in switch ON resistance occurs when operating at supply voltages less than 15 volts (see plot). Small signals have a 3 dB down frequency of 70 MHz (see insertion loss versus frequency plot).
ANALOG CURRENT
The analog switches in the ON state are JFETs biased in their triode region and act as switches for analog current up to the IA specification (see plot of IDS vs VDS). Some applications require pulsed currents exceeding the IA spec. For example, an integrator reset switch discharging a shunt capacitor will produce a peak current of IA(PEAK) = VCAP/RDS(ON). In this application, it is best to connect the source to the most positive end of the capacitor, thereby achieving the lowest switch resistance and REV. A

fastest reset times. The switch can easily handle any amount of capacitor discharge current subject only to the maximum heat dissipation of the package and the maximum operating junction temperature from which repetition can be established.
SWITCHING DISABLE NODE
This TTL compatible node is similar to the logic inputs INX but has an internal 2 A current source pull-up. If disable is left unconnected, it will assume the logic "1" state, then the state of the switches is controlled only by the logic inputs INX.
POWER SUPPLIES
Switching time tON and tOFF characteristics are plotted versus VANALOG and temperature. In all cases, tOFF is designed faster than tON to ensure a break-before-make interval for SPDT and DPDT applications. The disable input (DIS) has the same switching times (tON and tOFF) as the logic inputs (INX). Switching transients occurring at the source and drain contacts results from ac coupling of the switching FETs gate-to-source and gate-to-drain coupling capacitance. The switch turn ON will cause a negative going spike to occur and the turn OFF will cause a positive spike to occur. These spikes can be reduced by additional capacitance loading, lower values of RL, or switching an additional switch (with its extra contact floating) to the opposite state connected to the spike sensitive node.
This product operates with power supply voltages ranging from 12 to 18 volts; however, the specifications only guarantee device parameters with 15 volt 5% power supplies. The power supply sensitive parameters have plots to indicate effects of supply voltages other than 15 volts.
