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.
