SL74HC4051
Analog Multiplexer Demultiplexer
High-Performance Silicon-Gate CMOS
The SL74HC4051 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.
