74HC688

8-bit magnitude comparator

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.

特性

  • 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
