These devices contain four independent Exclusive-OR gates with open-collector outputs. They perform the Boolean functions Y = A ⊕ B = AB + AB in positive logic. A common application is a true/complement element. If one of the inputs is low, the other input will be reproduced in true form at the output. If one of the inputs is high, the signal on the other in.
