7486 - Quad XOR Gate

The 7486 is a quad 2-input XOR gate IC in the 74xx family, operating at 2-6V with low power consumption and high speed. It contains four independent XOR gates, each performing the Boolean function Y = A ⊕ B, outputting HIGH when inputs differ. Commonly used in digital circuits like adders, counters, and multiplexers, it’s available in 14-pin packages.
