The SN74ACT86D is a quadruple 2-input Exclusive-OR Gate. The device performs the Boolean functions Y = A ⊕ B = A\B + AB\ in positive logic. A common application is as a true/complement element. If one of the inputs is low, the other input is reproduced in true form at the output. If one of the inputs is high, the signal on the other input is reproduced inverted at the output.
