Overview
The CD74HC7266M96 is a quadruple 2-input XNOR gate integrated circuit produced by Texas Instruments. This device contains four independent 2-input XNOR gates, each performing the Boolean function Y = A ⊕ B in positive logic. It is part of the HC series, known for its wide operating voltage range and significant power reduction compared to LSTTL logic ICs. The CD74HC7266M96 is available in a 14-pin SOIC package and is suitable for a variety of digital logic applications due to its balanced propagation delay and transition times, and high noise immunity.
