SN74LS688
8-Bit Magnitude
Comparators
The SN74LS682, 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 and LS684 have P >Q outputs also.
The LS682, LS684 and LS688 are totem pole devices. The LS682
has a 20 kΩ pullup resistor on the Q inputs for analog or switch data.
