1. MUX and DeMUX truth table.
2. MUX and DeMUX behaviour test.
3. MUX structure using NAND gates.
A 2:1 MUX has the following symbol: |
A 1:2 deMUX has the following symbol: |
The truth table for the 2:1 MUX is: |
The truth table for the 1:2 MUX is: |
Test the 2:1 MUX behaviour using 74151 8-to-1 line data
selector/multiplexer with complementary outputs.
Connect the inputs of the MUX to Binary counter outputs
and follow the output on the scope.
Test the 1:2 DeMUX using 4051 DeMUX/MUX circuit.
Connect the inputs of the MUX to Binary counter outputs
and follow the output on the scope.
The schematics of a 2:1 MUX is the following:
Change the previous schematic in order to use only NAND gates.
Build the resulted circuit and test the MUX behaviour.
