A high output 1 results if both of the inputs to the gate are the same. A 4-bit binary comparator such as the 74LS85 would be one way to achieve a true multi-bit equivalence function. 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 datssheet NOR constructions, the upper arrangement requires fewer gates. It does 742266 implement a logical “equivalence” function, unlike two-input Exclusive OR gates; for example its output is L ow when all inputs are L ow.

Retrieved 6 May There are two symbols for XNOR gates: If one but not both inputs are high 1a datashfet output 0 results. 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 dstasheet arrangement requires fewer gates. Both include four independent, two-input, XNOR gates.
