1x4 Demux Circuit Diagram. This data bit is transmitted to the data bit of the o p lines which depends on the ab value and the control i p. This site uses cookies to offer you a better browsing experience.
So each combination will select only one data input. As you can see that we give selection line pins a and b are equal to one. This data bit is transmitted to the data bit of the o p lines which depends on the ab value and the control i p.
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.
It consists of 1 input line n output lines and m select lines. You can play with it in proteus also. The truth table of 1x4 de multiplexer is shown below. In this m selection lines are required to produce 2m possible output lines consider 2m n.
