SN74HC266D TI Logic Gates | 14-SOIC | Quad 2-Input XNOR, 2V-6V

Product Overview

The SN74HC266D from Texas Instruments is a quad 2-input XNOR gate IC in a 14-pin SOIC package. It belongs to the HC family, offering high-speed CMOS logic with low power consumption. The device performs the logical XNOR function (equivalence) on two inputs per gate, providing a high output when both inputs are equal. It operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. The SN74HC266D is ideal for digital systems requiring parity checking, data comparison, or encryption.
