CD74HC688PWR TI Comparators | 20-TSSOP | 8-Bit Identity, 2V to 6V

Product Overview

The CD74HC688PWR from Texas Instruments is a high-speed CMOS 8-bit identity comparator designed for use in advanced digital systems. It compares two 8-bit binary or BCD words and provides a low-impedance output when the two words are equal. The device operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial applications. Packaged in a compact 20-TSSOP, it offers a space-saving solution for modern electronic designs.
