Output Equation: \(Y = {\bf{A}} \oplus {\bf{B}} = \bar AB + A\bar B\)
Key Points:
1) The output is low when both the inputs are the same. Hence XOR gate can be used to know whether two digital inputs are identical.
2) The output is high when both the inputs are different.
3) It is also called stair case switch.
4) It is mostly used in parity generation & detection.
5) 4 NAND & 5 NOR logic gates required for realization of XOR gate .
