HD74HC684 - 8-bit Magnitude Comparator

General Description

These magnitude comparators perform comparisons of two eight-bit binary or BCD words.

All types provide P=Q outputs and provide P>Q outputs.

Key Features

  • 20 k pullup termination resistors on the Q inputs for analog or switch data. Type HD74HC682 HD74HC684 P=Q Yes Yes P>Q Yes Yes Output Enable No No 20 kΩ Pullup Yes No Features.
  • High Speed Operation High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) Function Table Input Data P, Q P=Q P>Q PQ H.
