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.
