Multiplexer(MUX) And Demultiplexer(DeMux)

Multiplexer Multiple input, one output A single input line is connected electrically to the output The selection of the input line is done via separate input

Multiplexer

What do we mean by Electrical? Connection is analog, not digital Any value of voltage is copied to output, and any input current is transmitted to the output It is as if the input and output have been shorted by a wire

What do we mean by Electrical?

Demultiplexer Opposite of multiplexing Multiple output, single input Input is electrically connected to one of the output lines Selection of output line is done via separate input

Demultiplexer

Whats the difference? Since the connection is electrical, same IC can act as multiplexer as well as demultiplexer We call this Mux-Demux In particular, the above IC is 4052 – a 4 * 1 Mux- Demux * 1 Mux-Demux

Other considerations Electrical connection is not perfect Unconnected pins are left floating
