Basic tutorial 4:1 Line Multiplexer using Basic Gates

For the students of 12th standard electronics and engineering here is the simple explanation of working of 4:1 Line Multiplexer using Basic Gates. This circuit simulation will give you a very clear idea about the working of 4:1 line mux using basic gates.

We know that the Mux is called as data selector circuit because out of number of data inputs it can select a particular signal and produce it at the output.

For more details refer our Digital Electronics Book written by Vidyasagar Sir, for the students of applied electronics of 12th standard. This book is also useful for polytechnic and engineering students.

The 4 possible conditions of Mux

Logic state of the circuit when S1=S0=0

Logic state of the circuit when S1=S0=0

Logic state of the circuit when S1=0 & S0=1

Logic state of the circuit when S1=0 & S0=1

Logic state of the circuit when S1=1 & S0=0

Logic state of the circuit when S1=1 & S0=0

Logic state of the circuit when S1=S0=1

Logic state of the circuit when S1=S0=1
