74HC688
Applications
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.
Features and benefits
- Compare two 8-bit words
- Output capability: standard
- ICC category: MSI
