3,447 views

The 74LS series of integrated circuits (ICs) was one of the most popular logic families of transistor-transistor logic (TTL) logic chips. 74LS series is a bipolar, low-power Schottky IC. 74LS86 contains four independent 2-input Exclusive-OR gates. They perform the Boolean functions Y = A ⊕ B = A’B + AB’ in positive logic.
