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 P >Q outputs also. The LS682, LS684 and LS688 are totem pole devices. The LS682 has a 20 kâĤ pullup resistor on the Q inputs for analog or switch data.
