... DIODE FIGURE 7. OVERVOLTAGE PROTECTION 7 ISL84781 Power-Supply Considerations The ISL84781 construction is typical of most single supply CMOS analog multiplexers, in that it has two supply pins: V+ and GND. V+ and GND drive the internal CMOS switches = 16ns, ON and set its analog voltage limits. Unlike switches with a 4V maximum supply voltage, the ISL84781 4 ...

... COM FIGURE 10. ON RESISTANCE vs SWITCH VOLTAGE 8 ISL84781 signal-path leakage current. All analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. This is why both sides of a given switch can show leakage currents of the same or opposite polarity ...
