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.
TYPE LS682 LS684 LS688 P=Q yes yes yes PQ yes yes no OUTPUT ENABLE no no yes OUTPUT CONFIGURATION totem-pole totem-pole totem-pole PULLUP yes no no
