Overview
SN74LS682, SN74LS684, 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 PQ 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.
