1x4 Demultiplexer Circuit Diagram. 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. We can use this ic in both digital and analog applications.
By applying control signal we can steer any input to the output. It is a cmos logic based ic belonging to a cd4000 series of integrated circuits. The data inputs of upper 8x1 multiplexer are i 15 to i 8 and the data inputs of lower 8x1 multiplexer are i 7 to i 0.
Thus a demultiplexer is a 1 to n device where as the multiplexer is an n to 1 device.
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. 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. Now let s observe its truth table the values of a 1 a 0 determine which of the outputs are set to the value of d in. In this m selection lines are required to produce 2m possible output lines consider 2m n.
