74HC688
description
The 74HC688 is an 8-bit magnitude parator. It performs parisons 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
- pare two 8-bit words
- Wide supply voltage range from 2.0 V to 6.0 V
- CMOS input levels
- CMOS low power dissipation
- High noise immunity
- Latch-up performance exceeds 100 m A per JESD 78 Class II Level B
- plies with JEDEC standards
- JESD8C (2.7 V to 3.6 V)
- JESD7A (2.0 V to 6.0 V)
- ESD protection:
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
- Specified from -40 °C to +85 °C and from -40 °C to +125 °C
