Detailed explanation-1: -A demultiplexer, sometimes abbreviated dmux, is a circuit that has one input and more than one output. It is used when a circuit wishes to send a signal to one of many devices.
Detailed explanation-2: -Detailed Solution. Multiplexer: It is a device that combines several inputs and outputs them into a single line. Demultiplexer: It is a device that reverses the process of multiplexer i.e. it converts data from a single input line to multiple output lines.
Detailed explanation-3: -The demultiplexer takes one single input data line and then switches it to any one of a number of individual output lines one at a time. The demultiplexer converts a serial data signal at the input to a parallel data at its output lines as shown below.
Detailed explanation-4: -Which device has one input and many outputs? Explanation: Demultiplexer takes data from one line and directs it to any of its N output depending on the status of its select lines.
Detailed explanation-5: -A De-multiplexer is a combinational circuit that has only 1 input line and 2N output lines. Simply, the multiplexer is a single-input and multi-output combinational circuit. The information is received from the single input lines and directed to the output line.
