Building Blocks of Computer:Demultiplexer


By on 02:52

Demultiplexer(demux) is a circuit that produce many outputs from one input or in simple words One to Many.



Now I discuss the example of Demux,

1)1:2 demux or 1 to 2 Demux:-



Functional Table:-

S(0)y(var.)
0I(0)
1I(1)



Logic Circuit:-



2)1:4 demux or 1 to 4 demux:-


Functional Table:-


S(0)S(1)y
00I(0)
01I(1)
10I(2)
11I(3)

Logic Circuit:-



3)1:8 demux or 1 to 8 demux:-


Functional Table:-


S(2)S(1)S(0)y(var.)
000I(0)
001I(1)
010I(2)
011I(3)
100I(4)
101I(5)
110I(6)
111I(7)

Logic Circuit:-
