3 Description

The CDx4HC405x and CDx4HCT405x devices are

digitally controlled analog switches that use silicon

gate CMOS technology to achieve operating speeds

similar to LSTTL with the low-power consumption of

standard CMOS integrated circuits.

These analog multiplexers and demultiplexers control

analog voltages that may vary across the voltage

supply range (for example, VCC to VEE). They are

bidirectional switches that allow any analog input to

be used as an output and vice versa. The switches

have low ON resistance and low OFF leakages. In

addition, all these devices have an enable control

that, when high, disables all switches to their OFF

state.
