Digital Demultiplexers:

A de-multiplexer is a logic device that switches one common input line to one of many independent output lines.

A data distributor, often known as a demultiplexer or "Demux" for short, is the inverse of the multiplexer we explored in the last tutorial.

A demultiplexer takes one input data line and switches it one by one to any of many different output lines.

OThe input will be routed to any of the four outputs dependign on the select signal value

if select is 00: F will pass to A

if select is 01: F will pass to B

if select is 10: F will pass to C

if select is 11: F will pass to D

This is what a Demux looks from the inside in terms of logic gates
