The CD74AC86 is a quadruple 2-input exclusive-OR gate. This device performs the Boolean function Y = A ⊕ B or Y = AB + 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.
The CD74AC86 performs the Boolean function Y = A⊕B (exclusive‑OR) for each of its four gates. It is designed for true/complement applications, offering balanced propagation delays, low power consumption, and a fan‑out of up to 15 devices. The device operates from 1.5 V to 5.5 V and provides up to +24 mA output drive current.
Electrical characteristics include a typical propagation delay of about 3 ns, power‑dissipation capacitance of 57 pF, and ESD protection exceeding 2 kV per MIL‑STD‑883. The part is available in PDIP, SOIC and tape‑and‑reel packages, with detailed mechanical drawings and RoHS‑compliant options. Ordering information and package options are listed in the packaging section.
