Integrated Circuits Used

74LS153 74LS32 74LS04

Description

This circuit implements an 8:1 multiplexer using the 74153 IC. Inputs D0–D7 are controlled via switches, and select lines S0–S2 determine the active input. The output is monitored using an LED. The setup includes power and ground connections, and is designed for lab verification of multiplexing logic.
