DESCRIPTION
The M74HCT4051 is a single eight-channel
analog
MULTIPLEXER/DEMULTIPLEXER
fabricated with silicon gate C
2
MOS technology
and it is pin to pin compatible with the equivalent
metal gate CMOS4000B series.
It contains 8 bidirectional and digitally controlled
analog switches.

A built-in level shifting is included to allow an input
range up to
±6V
(peak) for an analog signal with
digital control signal of 0 to 6V.
V
EE
supply pin is provided for analog input
signals. It has an inhibit (INH) input terminal to
disable all the switches when high, compatible
with TTL output level. For operation as a digital
multiplexer/demultiplexer, VEE is connected to
GND. A, B and C control inputs select one channel
out of eight channels; they are compatible with
TTL output level.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
