8-BIT MAGNITUDE

COMPARATORS

The SN54 / 74LS682, 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鈩?pullup resistor on the Q inputs for analog or switch data.
