Demultiplexer Diagram. Comparator and digital magnitude comparator. 1 to 4 demultiplexer the input bit is data d with two select lines a and b.
The demultiplexer circuit is shown in the above diagram. Schematic diagram of 1 to 2 demultiplexer using logic gates schematic of 1 to 2 demultiplexer using logic gates is given below. It has one data input d 2 n possible outputs y 0 y 1 y 2 y 2n 1 n selection lines s 0 s 1 s n.
Demultiplexer needs and gates equal to the number of output channels and not gates equal to the number of control signals.
It distributes one input line to one of 8 output lines depending on the combination of select inputs. The 1 to 8 demultiplexer circuit diagram is shown below. It is used when a circuit intends to send a signal to one of many devices. 1 to 4 demultiplexer block diagram.
