General Description

The MM74HC4316 devices are digitally controlled analog switches implemented in advanced silicon-gate CMOS technology. These switches have low “ON” resistance and low “OFF” leakages. They are bidirectional switches, thus any analog input may be used as an output and vice-versa. Three supply pins are provided on the MM74HC4316 to implement a level translator which enables this circuit to operate with 0–6V logic levels and up to ±6V analog switch levels. The MM74HC4316 also has a common enable input in addition to each switchs control which when HIGH will disable all switches to their OFF state. All analog inputs and outputs and digital inputs are protected from electrostatic damage by diodes to VCC and ground.
