XNOR gate – Wikipedia

Retrieved 6 May 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”. 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. This article needs additional citations for verification.

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:.

This article needs additional citations for verification. There are two symbols for XNOR gates: For the NOR constructions, the upper arrangement requires fewer gates. A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. For the NOR constructions, the upper arrangement requires fewer gates. If one but not both inputs are high 1a low output 0 results.

Both include datasheeet independent, two-input, XNOR gates. 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 742266 table:.

A high output 1 results if both of the inputs to the gate are the same. By using this site, you agree to the Terms of Use and Privacy Policy. Please help improve this article by adding citations to reliable sources.

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.
