Demultiplexer

A demultiplexer, also known as a demux, is a digital circuit that takes a single input and distributes it to multiple outputs based on the control signals. It is the opposite of a multiplexer, which takes multiple inputs and selects one output based on the control signals.

In simpler terms, a demultiplexer takes a single input and directs it to one of several output lines based on the control signals. The control signals determine which output line the input will be sent to.

Demultiplexers are commonly used in digital systems to route data or signals to different destinations. They can be used in various applications, such as data transmission, memory addressing, and signal routing.

The demultiplexer is often represented by a block diagram with a single input line, multiple output lines, and control signals that determine the output selection. It can have 2^n output lines, where n is the number of control signals.

Overall, a demultiplexer is a fundamental component in digital circuits that allows for the distribution of a single input to multiple outputs based on control signals.
