Serial or parallel expansion without extra gating
Low power CMOS
CMOS and TTL input options
Key applications
Process controllers
Servo-motor control

The 74HC/HCT688 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). The 74HC/HCT688 are 8-bit magnitude comparators. They perform comparison of two 8-bit binary or BCD words. The output provides P = Q.

Compare two 8-bit words
Output capability: standard
