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.

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.

For the NOR constructions, the upper arrangement requires fewer gates. 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”. December Learn how and when to remove this template message.

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:. Views Read Edit View history.

Please help improve this article by adding citations to reliable sources. A 4-bit vatasheet comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. 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:.
