A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. This article needs additional citations for verification. For the NAND constructions, the lower arrangement offers the datashest of a shorter propagation delay the time delay between an input changing and the output changing.

It does not implement a logical “equivalence” function, unlike two-input Exclusive OR gates; for example its output is L ow when all inputs are L ow. If one but not both inputs are high 1a low output 0 results. December Learn how and when to remove this template message.

The two-input version implements logical equalitybehaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”.
