Description

The M74HC4051 is a single 8-channel analog
multiplexer/demultiplexer fabricated with silicon

2

gate C
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 ± 6 V (peak) for an analog signal with
digital control signal of 0 to 6 V.

MOS technology, pin-to-pin compatible

SOP-16

The V

supply pin is provided for analog input

EE

signals. It has an inhibit (INH) input terminal to
disable all the switches when is at high level. For
operation as a digital multiplexer/demultiplexer,
V

is connected to GND.

EE

A, B and C control inputs select one channel out
of eight. All inputs are equipped with protection
circuits against static discharge and transient
excess voltage.
