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.
