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 k

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