For 2-input EX-OR gate, if one input is A, the other input is B, and the output is Y. Then the Boolean expression for EX-OR (XOR) function (gate) is Y=AB The output Y is true if either input A or if input B is true, but not both.

Y= ( (A and NOT B) or (NOT A and B) ) ;

The XOR gate turns on only if A OR B (but not both) 1 (since there already is OR this one is called exclusive OR (XOR)).

Boolean Expression (XOR Gate): Y=AB

XOR Gate Symbol

Truth Table (XOR Gate)

{| ! A ! B ! Y ! 0 ! 0 ! 0 ! 1 ! 0 ! 1 ! 0 ! 1 ! 1 ! 1 ! 1 ! 0 |}
