COMPARATORS
  The SN54 / 74LS682, 684, 688 are 8-bit magnitude comparators. These
device types are designed to perform comparisons between two eight-bit
binary or BCD words. All device types provide P = Q outputs and the LS682                                8-BIT MAGNITUDE
and LS684 have P>Q outputs also.                                                                          COMPARATORS
  The LS682, LS684 and LS688 are totem pole devices. The LS682 has a
20 k pullup resistor on the Q inputs for analog or switch data.                                         LOW POWER SCHOTTKY
