The scenario
Design a 2-to-1 multiplexer using only NAND gates to select between two data inputs based on a control signal, demonstrating NAND universality.
What is in this drawing
Read the decisions behind it.
01
Use only NAND gates
02
Implement NOT gate via NAND with tied inputs
03
Combine NAND stages to realize the OR function for output
Useful when implementing combinational logic with a single gate type, such as in NMOS technology or for educational exercises on gate universality.
