A Demultiplexers
is a circuit that receives information on a single line and transmit the
information on one of 2*n possible output lines.
The selection of
specific output line is controlled by the value of n selection lines.
It has one input data and 2*n output lines.
1:4 Demultiplexers:
1:8 Demultiplexers:
Design 1:8 Demultiplexer using two 1:4 Demultiplexers?
Implementation of combinational logic circuit using Demultiplexer?
Application of Demultiplexers:
It can used as the
decoder:
It can be used as
a data distributer.
It is used in time
division multiplexing at the receiving end.
It is used to
implement Boolean expression.
