XOR Gate | truth table of two-input XOR gate

XOR Gate

The XOR gate has two or more inputs and one output. The symbols of two-input and three-input XOR gates are


Symbol of XOR gate

Symbol of XOR gate: (a) two-input, (b) three-input

The Boolean expression of the output (Y) for a two-input XOR gate is given as follows: -


The truth table of two-input XOR gate is


The truth table of two-input XOR gate is


The XOR logic function is associative; that is, any XOR function with more than two inputs can be realized using two-input XOR functions.

 For example,

Y (A, B, C) = (A ⊕ B) ⊕ C = A ⊕ (B ⊕ C)
