Multiplexer & De-Multiplexer

Multiplexer  is  a  circuit which transmits a large number of info signals (which are inputs)  over a small number of info signals (that are output).

An electronic multiplexer makes it possible for several signals to share one device or resource. A multiplexer is often used with a complementary De-multiplexer on the receiving end.

Example :-

                     

TYPES OF MULTIPLEXER:-

       1 TO 4 LINE MULTIPLEXER

     1 TO 8 LINE MULTIPLEXER

       1 TO 16 LINE MULTIPLEXER

De-Multiplexer  is  a  circuit which transmits a large number of info signals (which are output)  over a small number of info signals (that are input).

De-multiplexers are sometimes convenient for designing general purpose logic, because if the de-multiplexer's input is always true, the demultiplexer acts as a decoder. This means that any function of the selection bits can be constructed by logically OR-ing the correct set of outputs.
