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.

74266 – Quad 2-Input Exclusive NOR Gate

47266 From Wikipedia, the free encyclopedia. It daatasheet 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.

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:. If one but not both inputs are high 1a low output 0 results. By using this site, you agree to the Terms of Use and Privacy Policy.
