74LS68 Datasheet (ON Semiconductor)

74LS68, LOW-POWER SCHOTTKY

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 kΩ pullup resistor on the Q inputs for analog or switch data.
