description

These

magnitude

comparators

perform

comparisons of two 8-bit binary or BCD words.

These devices provide P = Q and P > Q outputs.

The SN54HC684 is characterized for operation

over the full military temperature range of –55°C

to 125°C. The SN74HC684 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.
