The document summarizes an experiment to verify the truth table of a NAND gate using an IC 74LS00 chip. The experiment involved connecting the IC to switches as inputs and an LED as the output on a breadboard. By providing different combinations of input values to the switches according to the NAND truth table, the LED output matched the expected output value each time, successfully verifying the truth table.

- 2. Lab. No. 5 Objective: To perform operation of NAND gate according to NAND gate truth table using IC 74LS00 Apparatus: 1. IC 74LS00 2. Wires 3. Cutter 4. AM 2001 Trainer Integrated Circuit (IC): AM Trainer 2001: 74LS00
- 3. Truth Table of OR gate: Truth table Inputs Output A B C = A . B 0 0 1 0 1 1 1 0 1 1 1 0 Procedure: 1. I took wires and cut them with the help of cutter. 2. I connect the IC on the breadboard. 3. I took a wire (white) and connect it at 7 pin and grounded it. 4. I connect two wires (Orange and blue) at pin 1 and 2 and connected it to switches S2 and S3. 5. Then I connected one end of brown wire with pin 3 to get output and other end with LED (l4) 6. Then we give power supply through pin 14 with the help of another wire (green) which is +5V 7. Now we started giving inputs through switches S2 and S3 respectively. 8. Firstly, we give 1 input to switch S2 and 0 input to switch S3, and as a result we get LED (L4) turn on, which indicates that we get output 1. 9. Secondly, we give 0 input to switch S2 and 1 input to switch S3, and as a result we get LED (L4) turn on, which indicates that we get output 1. 10. Thirdly, we give 1 input to switch S2 as well as 1 input to switch S3, and as a result we get LED (L4) turn on, which indicates that we get output 0. 11. At the end, we give 0 input to switch S2 as well as 0 input to switch S3, and as a result we get LED (L4) remains turn off, which indicates that we get output 1. Result: Hence I verified the truth table of NAND gate using IC 74LS00.
