description

These magnitude comparators perform comparisons of two 8-bit binary or BCD words. The 'HC682 feature 100- pullup termination resistors on the Q inputs for analog or switch data.

The SN54HC682 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC682 is characterized for operation from -40°C to 85°C.

The P < Q\ function can be generated by applying P = Q\ and P > Q\ to a 2-input NAND gate.
