DESCRIPTION

· The 74HC688 is an 8-bit magnitude comparator designed for comparing two 8-bit binary or BCD words.

· It includes clamp diodes in inputs, allowing the use of current limiting resistors for interfacing with voltages exceeding VCC.

FEATURES

· Compares two 8-bit words with a wide supply voltage range from 2.0 V to 6.0 V.

· Features CMOS input levels and low power dissipation, ensuring high noise immunity.

· Latch-up performance exceeds 100 mA per JESD 78 Class II Level B.

· Complies with JEDEC standards: JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V).

· Offers robust ESD protection: HBM exceeds 2000 V and CDM exceeds 1000 V.

· Operational temperature ranges from -40 °C to +85 °C and -40 °C to +125 °C.

APPLICATIONS

· Suitable for applications requiring precise 8-bit binary or BCD word comparisons.

· Ideal for systems operating within a wide voltage range and requiring low power consumption.

· Used in environments demanding high noise immunity and robust ESD protection.
