SN74LS682, SN74LS684,

SN74LS688

8−Bit Magnitude

Comparators

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.

has a 20 kΩ pullup resistor on the Q inputs for analog or switch data.
