- A 1-to-4 demultiplexer is a digital device that takes a single input signal and channels it to one of four outputs based on the values of two selection lines. It allows for efficient data routing in digital circuits, enabling one data source to be directed to multiple destinations without requiring multiple separate input lines.

Feb 24, 2012 · Working Principle: It operates by using a control signal to select which output line will receive the input data. Types of Demultiplexers: Includes 1-to-2, 1-to-4, 1-to-8, and 1-to-16 types, based on the number of output lines. Communication Applications: Demultiplexers are crucial in communication systems for transmitting and receiving signals.
Sep 19, 2024 · 1-to-4 Demultiplexer. A 1-to-4 demultiplexer has a single input (D), two selection lines (S1 and S0) and four outputs (Y0 to Y3). The input data goes to any one of the four outputs at a given time for a particular combination of select lines.
- 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.
Jul 29, 2024 · A 1×4 DEMUX has only one input which is denoted as I. There are two selection lines i.e. S1 and S0. At last, the DEMUX has output lines including Y3, Y2, Y1 &Y0.
The 1:4 Demultiplexer consists of 1 input signal, 2 control signals and 4 output signals. The number of the output signal is always decided by the number of the control signal and vice versa. We have already studied the equation in our previous article of Multiplexer.
Oct 12, 2022 · 1 : 4 demultiplexer. The block diagram and circuit of 1-to-4 demultiplexer are shown below. There are four possible outputs Y 0, Y 1, Y 2, Y 3 and a single input D. The single data input is sent to one of the four outputs as per the selection line input.
The 1×4 Demultiplexer has 1 input line (I), 2 select line (S 0 and S 1), and 4 output lines (Y 0, Y 1, Y 2, and Y 3). The logic level applied to the select lines determines the output line to which the input data (I) will be transmitted.
