Two Input XOR Gate Using OR-NAND & AND
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 XOR gate practically. 1. This is a two input XOR gate circuit. 2. Before understanding this circuit, first see following previous circuits; i) Two Input OR Gate ii) Two Input AND Gate iii) Two Input NAND Gate and iv) Single Input NOT Gate in Logic Gates category. 3. There are several ways to make two input XOR Gate, but here XOR gate is made by using combination of OR, NAND and AND Gate. 4. The truth table of XOR gate is: In 1: In 2 : Out 0 : 0 : 0 0 : 1 : 1 1 : 0 : 1 1 : 1 : 0 5. From the above truth table we can see that if odd number of inputs of XOR gate is logic one (1) then output is logic one (1). 6. The output is logic zero (0) when all inputs are logic zero (0) or when even number of inputs are logic one (1). 7. Here logic one (1) means 5V and logic zero (0) means 0V or ground. Application: 1. This circuit is used to understand the working of XOR gate. 2. This circuit is used when you don't have XOR gate IC and you need XOR gate. Download these files for performing more experiments.
