3 Description

The CD74HC4067 and CD74HCT4067 devices are

digitally controlled analog switches that use silicongate

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. They are bidirectional switches, thus

allowing any analog input to be used as an output and

vice-versa. The switches have low on resistance and

low off leakages. In addition, these devices have an

enable control that, when high, disables all switches

to their off state.
