CD74HCT688M96 TI 8-Bit Identity Comparator | 20-SOIC | 4.5V-5.5V, 8-Bit

Product Overview

The CD74HCT688M96 from Texas Instruments is a high-speed 8-bit identity comparator designed for digital systems requiring fast and accurate comparison of two 8-bit words. Fabricated with advanced HCMOS technology, it offers the low power consumption of CMOS with the speed of LSTTL. The device compares two 8-bit inputs (P and Q) and provides a low-impedance output (P=Q) when all bits match. It operates over a wide supply voltage range of 4.5V to 5.5V, making it ideal for 5V digital systems. The 20-SOIC package enables compact PCB designs.
