Two Input AND Gate
Category: Logic Gates
Designer: RANA MUHAMMAD ADNAN KHALIL
Notes
This circuit is designed and simulated in Proteus 7.10. In this circuit you will learn how to make AND gate practically. 1. This is a two input AND gate circuit. 2. The truth table of AND gate is: In 1: In 2 : Out 0 : 0 : 0 0 : 1 : 0 1 : 0 : 0 1 : 1 : 1 3. From the above truth table we can see that if any input of AND gate is logic zero (0) then output is logic zero (0). 4. The output is logic one (1) only when all inputs are logic one (1). 5. Here logic one (1) means +5Vdc and logic zero (0) means 0V or ground. 6. The number of inputs can be increased by increasing the number of diodes. Application: 1. This circuit is used to understand the working of AND gate. 2. This circuit is used when you don't have AND gate IC and you need AND gate. Download these files for performing more experiments.
