3 Description

The CDx4HC405x and CDx4HCT405x device is a

digitally controlled analog switch that uses silicon

gate CMOS technology to achieve operating speeds

similar to LSTTL with the low-power consumption of

standard CMOS integrated circuits.

This analog multiplexer and demultiplexer controls

analog voltages that may vary across the voltage

supply range (for example, V

CC

to V

EE

). It is a

bidirectional switch that allows any analog input to be

used as an output and vice versa. The switch has low

ON resistance and low OFF leakages. In addition, this

device has an enable control that, when high, disables

all switches to their OFF state.
