IC 74HC266 (Quad 2-Input XNOR Exclusive-NOR Gate) 74266

Description

1. Quad 2-Input XNOR Gates: The 74HC266 contains four separate XNOR gates, each with two data inputs (A and B).
2. Exclusive-NOR Function: The XNOR gate produces an output that is high (1) when both inputs are the same (both high or both low). It is sometimes referred to as an equivalence gate because it checks if the two inputs are equivalent.
3. High-Speed Operation: The 74HC266 is designed for high-speed digital logic operations.
