3 Description

The CD74HCx4067-Q1 device is a digitally controlled

analog switch that utilizes 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. It is a bidirectional switch, thus allowing

any analog input to be used as an output and viceversa.

The switch has low (on) resistance and low

(off) leakages. In addition, the device has an enable

control that, when high, disables all switches to their

off state.
