Demultiplexer (DEMUX)

A Demultiplexer is a combinational circuit having one input and multiple outputs. A DEMUX consist of only one input, ‘n’ outputs and  ‘m’ numbers of selection inputs. There is an Enable input which is used to enable and disable the De-multiplexer. In simple words, it is the reverse of a Multiplexer.  The relation between n output lines and m selection lines is 2m= n.

In digital electronics, the Demultiplexer (DEMUX) is used where we need multiple outputs from one input.
