A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. For the NAND constructions, the lower arrangement offers the advantage of a shorter propagation delay the time delay between an input dstasheet and the output changing. Retrieved from ” https: The two-input version implements logical equalitybehaving according to the truth table to the right, and hence the gate datasheeet sometimes called an “equivalence gate”. This article needs additional citations for verification.

## 74266 – Quad 2-Input Exclusive NOR Gate

Both include four independent, two-input, XNOR gates. Retrieved 6 May Articles needing additional references from December All articles needing additional references Commons category link is on Wikidata. 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. A high output 1 results if both of the inputs to the gate are the same.

However, extending the concept of the binary logical operation to three inputs, the SN74S with two shared “C” and four independent “A” and “B” inputs for its four outputs, was a device that followed the truth table:.
