74HC688 - Philips

74HC688 8-bit magnitude comparator

74HC/HCT688 The 74HC/HCT688 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC/HCT688 are 8-bit magnitude comparators. They perform comparison of two 8-bit binary or BCD words. The output provides P = Q. QUICK REFERENCE DATA GND = 0 V; Tamb =.
