These magnitude comparators perform comparions of two eight-bit binary or BCD words. All types provide P=Q outputs and all except 'LS688 provide P>Q outputs as well.The 'LS682 ,'LS684, 'LS686, and 'LS688 have totem-pole outputs, while the 'LS685 and 'LS687 have open-collector outputs. The 'LS682 features 20-kΩ pullup termination resistors on the Q inputs for analog or switch data.
