The number of control lines in a multiplexer is 5, identify the MUX.

Multiplexer:

• A multiplexer is Many to one data selector.
• A multiplexer selects one of the many data available at its input depending on the bits on the select line.
• For 2m inputs, there are m select lines that determine, which input is to be connected to the output, i.e.

          Number of control lines = log2(number of input lines)

So, m control lines can create 2m combinations

Calculation:

Given:

Control lines in a multiplexer is 5.

5 control lines can create 25 = 32 combinations

Hence, the size of Mux is 32 ∶ 1
