DESCRIPTION
The M54HC4051 is a single eight-channel analog MULTIPLEXER/DEMULTIPLEXER fabricated with silicon gate C2MOS 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.
VEE 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, VEE 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.
