74HC688
8-bit magnitude comparator
Rev. 4 — 16 July 2021
Product data sheet
1. General description
The 74HC688 is an 8-bit magnitude comparator. It performs comparisons of two 8-bit binary or
BCD words. Inputs include clamp diodes. This enables the use of current limiting resistors to
interface inputs to voltages in excess of VCC
.
2. Features and benefits
•
Compare two 8-bit words
•
Wide supply voltage range from 2.0 to 6.0 V
CMOS input levels
CMOS low power dissipation
High noise immunity
Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Complies with JEDEC standards
