1x4 Demux Circuit Diagram. As an example a device that passes one set of two signals among four signals is a two bit 1 to 2 demultiplexer. The 1 to 4 demultiplexer consists of one input four outputs and two control lines to make selections the below diagram shows the circuit of 1 to 4 demultiplexer.
1x4 de multiplexer has one input i two selection lines s 1 s 0 and four outputs y 3 y 2 y 1 y 0. The 1x4 demultiplexer circuit diagram is shown below. As you see from this circuit diagram we are getting output on x and y pins according to the above table.
Since there are n selection lines there will be 2 n possible combinations of zeros and ones.
The block diagram of 1x4 de multiplexer is shown in the following figure. According to the selection lines multiplexer selects x3 and y3 input. In this case d3 is transmitted to the output and y d3. As you can see that we give selection line pins a and b are equal to one.
