74HC688 - 8-Bit Identity Comparators

Datasheet Summary

Description

These identity comparators perform comparisons of two 8-bit binary or BCD words.

An output-enable (OE) input may be used to force the output to the high level.

Features

  • Wide operating voltage range of 2 V to 6 V.
  • High-current outputs drive up to 10 LSTTL loads.
  • Low power consumption, 80-μA max ICC.
  • Typical tpd = 14 ns.
  • ±4-mA output drive at 5 V.
  • Low input current of 1 μA max.
  • Compare two 8-bit words 2.
