Demultiplexer:

It is a combinational circuit which receives 1-bit information and puts this information on the line which is selected by the binary input on the selection lines. This is different from decoder circuit as there is also an information line and we don’t have to put 1 every time on output (as in decoder) but the bit which is present on information line. It is also generally called by Demux.

Following is block representation for Demux

We can also have n-bit inputs in place of 1-bit inputs and hence we’ll have n-bit output which can be represented as
