3 Description
The CDx4HC405x and CDx4HCT405x device 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 (for example, V
CC
to V
EE
). It is a
bidirectional switch that allows any analog input to be
used as an output and vice versa. The switch has low
ON resistance and low OFF leakages. In addition, this
device has an enable control that, when high, disables
all switches to their OFF state.
