Texas Instruments SN74LS86AN Quad 2-Input XOR Gate IC, 14-Pin DIP

The Texas Instruments SN74LS86AN is a quad 2-input exclusive-OR (XOR) gate integrated circuit, built with reliable low-power Schottky (LS) TTL technology. This compact device contains four independent logic gates, each performing the essential Boolean XOR function. It operates as a true/complement element: when one input is held low, the signal at the other input is reproduced in true form at the output. Conversely, when one input is held high, the signal at the other input is inverted at the output.

This versatile logic chip is characterised for robust commercial and industrial operation. With TTL-compatible inputs and outputs, it is designed for seamless integration into a wide range of digital systems. A common application is in parity generation and checking circuits, binary adders, and controlled inverters, where its exclusive-OR functionality is critical.
