EMULTIPLEXER
High-Performance Silicon-Gate CMOS
The IN74HC4051 utilize silicon-gate CMOS technology to
achieve fast propagation delays, low ON resistances, and low
OFF leakage currents. These analog multiplexers/demultiplexers
control analog voltages that may vary across the complete power
supply range (from V
CC
to V
EE
).
The Channel-Select inputs determine which one of the Analog
Inputs/Outputs is to be connected, by means of an analog
switch, to the Common Output/Input.When the Enable pin is
high, all analog switches are turned off.
The Channel-Select and Enable inputs are compatible with
standard CMOS outputs; with pullup resistors, they are
compatible with LS/ALSTTL outputs.
