3 Description

The CD74HC4051-EP 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 (that is, VCC to VEE). These bidirectional

switches allow the use of any analog input as an

output and vice versa. The switches have low ONresistance

and low OFF leakages. In addition, the

device has an enable control (E) that, when high,

disables all switches to their OFF state.
