De-multiplexer. A De-multiplexer is a combinational circuit that has only 1 input line and 2 N 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.
A Demultiplexer is a combinational logic circuit that accepts a single input and distributes it over several output lines. Demultiplexer is also termed as DEMUX in short. As Demultiplexer is used to transmit the same data to different destinations, hence it is also known as data distributor.
Jul 29, 2024 · Demultiplexer receives digital information from a single source and converts it into several sources. In this article, we are going to have a detailed discussion on the Applications of DEMUX. Table of Content
- 1-to-4 Channel De-multiplexer. Output Select. Data Output. Selected b a 0 A 1 B C D. The Boolean expression for this 1-to-4 Demultiplexer above with outputs A to D and data select lines a, b is given as
- Demultiplexer Output Line Selection. As with the previous multiplexer circuit, adding more address line inputs it is possible to switch more outputs giving a 1-to-2 data line outputs.
- 4 Channel Demultiplexer using Logic Gates. The symbol used in logic diagrams to identify a demultiplexer is as follows.
- The Demultiplexer Symbol. Again, as with the previous multiplexer example, we can also use it to digitally control the gain of an operational amplifier as shown.
Sep 19, 2024 · A Demultiplexer is a combinational logic circuit that receives the information on a single input line and transmits the same information over one of ‘n’ possible output lines.
Feb 24, 2012 · Demultiplexer Definition: A demultiplexer (demux or data distributor) is defined as a circuit that distributes multiple outputs from a single input. Working Principle: It operates by using a control signal to select which output line will receive the input data.
Oct 12, 2022 · Demultiplexer or Demux is a combinational circuit that distributes the single input data to a specific output line. The control inputs or selection lines are used to select a specific output line from the possible output lines. Demultiplexer works opposite to that of the multiplexer.
