Product Summary

The 74HC688D is a 8-bit magnitude comparator. The 74HC688D is high-speed Si-gate CMOS devices and is pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 74HC688D8 are 8-bit magnitude comparators. They perform comparison of two 8-bit binary or BCD words. The output provides P = Q.
