Since 21 Aug Design your application so that the product is used within the ranges guaranteed by Hitachi particularly for maximum rating, operating supply voltage range, heat radiation characteristics, installation conditions and other characteristics. Otherwise, we would notice the Buyer for any delay. Even within the guaranteed ranges, consider normally foreseeable.

XNOR gate circuit using three mixed gates. Datasheets are readily available in most datasheet databases and suppliers. Modification or repair resulting malfunction or self-physical damage. All product names are trademarks of their respective companies.

This product is not designed to be radiation resistant. If one but not both inputs are high 1a low output 0 results. 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:.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Even within the guaranteed ranges, consider normally foreseeable failure rates or failure modes in semiconductor devices and employ systemic measures such as fail- safes, so that the equipment incorporating Hitachi product does not cause bodily injury, fire or other consequential damage due to operation of the Hitachi product.

If we did not receive the payment after 48 hours, the order will automatically be canceled. There are two symbols for XNOR gates: For the NOR constructions, the upper arrangement requires fewer gates. Confirm that you have received the latest product standards or specifications before final design, purchase or use. For further information write to: Hitachi Asia Hong Kong Ltd.

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”. Continue Shopping Add To List.

This article needs additional citations for verification. Hitachi Semiconductor America Inc. Hitachi bears no responsibility for failure or damage when used.


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 page was last edited on 24 Octoberat 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 datasheey propagation delay the time delay between an input changing and the output changing.
