In the 8 to 1 multiplexer, there are total eight inputs, i.e., A0, A1, A2, A3, A4, A5, A6, and A7, 3 selection lines, i.e., S0, S1and S2 and single output, i.e., Y. On the basis of the combination of inputs that are present at the selection lines S0, S1, and S2, one of these 8 inputs are connected to the output. The block diagram and the truth table of the 8×1 multiplexer are given below.

**Truth Table:**

The logical expression of the term Y is as follows:

Y=S0'.S1'.S2'.A0+S0.S1'.S2'.A1+S0'.S1.S2'.A2+S0.S1.S2'.A3+S0'.S1'.S2 A4+S0.S1'.S2 A5+S0'.S1.S2 .A6+S0.S1.S3.A7

Logical circuit of the above expression is given below:
