Introduction

AI Translation

These identity comparators are used to compare two 8-bit binary or BCD words. The Output Enable (OE) input can be used to force the output to a high level.

Features

AI Translation
  • Wide operating voltage range: 2V to 6V
  • High current output drives up to 10 LSTTL loads
  • Low power consumption, I<sub>CC</sub> max = 80 μA
  • t<sub>pd</sub> typical = 14 ns
  • Output drive ±4 mA at 5V
  • Low input current, max 1 μA
  • Compares two 8-bit words
