Combinational Logic: Analog multiplexer/demultiplexers

Analog multiplexer/demultiplexers
Example: 74VHC4051, 74VHC4052, 74VHC4053

An analog multiplexer incorporates analog switches (see the next page) to select one signal from multiple analog inputs and forward it to a single output line. The analog multiplexer can also be used as a demultiplexer since analog switches can transfer a signal bidirectionally.

Analog multiplexer/demultiplexers can be used to transfer both analog and digital signals.
