The circuit diagram for the 1-to-2 demultiplexer:
The circuit mentioned above can be expanded in two different ways. The number of signals can be increased or the number of inputs can be increased. Increasing the number of signals needs a larger line decoder, and increasing the number of signals that are transmitted is easier.
