ElectronicsThe NTE74LS266 with XNOR Gate 4-Element 2-IN Bipolar 14-Pin PDIP from NTE Electronics is an integrated circuit (IC) designed for use in digital logic systems. This logic IC has four input pins for connecting two binary data inputs (A and B) and two enable inputs (G1 and G2) to the XNOR circuit. The XNOR, also known as an Exclusive NOR, gates two binary digital inputs, A and B, and outputs 1 if each input (A and B) is the same (i.e. if A = B), and 0 if they are not the same. The device is manufactured using low-noise, low-power silicon gate CMOS technology, and comes encapsulated in a 14 Pin PDIP package for easy mounting and connection. This versatile device is suitable for use in a variety of applications, including computers, communications systems and robotics.
