com 54AC520 • 54ACT520 8-Bit Identity Comparator September 1998 54AC520 • 54ACT520 8-Bit Identity Comparator General Description The ’AC/’ACT520 are expandable 8-bit comparators.
They compare two words of up to eight bits each and provide a LOW output when the two words match bit for bit.
The expansion input IA = B also serves as an active LOW enable input.
