Description
The M74HC4051 is a single 8-channel analog
multiplexer/demultiplexer fabricated with silicon
gate C
2
MOS technology, 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
±
6 V (peak) for an analog signal with
digital control signal of 0 to 6 V.
The V
EE
supply pin is provided for analog input
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
EE
is connected to GND.
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.

Maximum ratings
Stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.
