74266 – Quad 2-Input Exclusive NOR Gate

A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. This page was last edited on 24 Octoberat Retrieved 6 May If one but not both inputs are high dtasheeta low output 0 results.

For the NAND constructions, the lower arrangement offers the advantage of a shorter propagation delay the time datxsheet between an input changing and the output changing. 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”. For the NAND constructions, the lower arrangement offers the advantage of a shorter propagation delay the time delay between an input changing and the output changing.
