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

• Complies with JEDEC standard: no. 7A

• ESD protection:

– HBM JESD22-A114-F exceeds 2000 V

– MM JESD22-A115-A exceeds 200 V

• Multiple package options

• Specified from -40 °C to +85 °C and from -40 °C to +125 °C
