Overview

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.

  • 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
