students will explore the basic logic gates in order to determine the behavior of the logic gates. 1. Logic Gates: For this , you will need a NOT gate, and one each of a two-input AND, OR, NOR and NAND integrated circuits. At the end of the lab, you should have measured five gates. 2. Data sheet: Find the data sheet for each IC a. Using the voltage ranges indicated for Vcc and ground.powers the IC.

Truth table: Apply the voltages indicated for VIH and VIL to the inputs of each gate to obtain the truth table for each IC. a. Apply different input combinations and measure the corresponding outputs (see examples below).
