74HC688 Description

Short technical summary and product information.

The 74HC688 is an 8-bit magnitude comparator designed to compare two 8-bit binary or BCD words. It offers a wide supply voltage range from 2.0 V to 6.0 V, making it versatile for various applications.

 

This comparator operates reliably within a temperature range of -40 °C to +125 °C. It features CMOS input levels and low power dissipation, characteristic of CMOS technology. The device also provides high noise immunity and robust ESD protection, exceeding 2000 V for HBM and 1000 V for CDM.

 

Available in SO20 and TSSOP20 packages, the 74HC688 is suitable for surface mount applications. Its latch-up performance exceeds 100 mA per JESD 78 Class II Level B, ensuring durability in demanding environments.

 

Key features include the ability to compare two 8-bit words and compliance with JEDEC standards JESD8C and JESD7A.
