74F521 8-Bit Identity Comparator

The 74F521 is an expandable 8-bit comparator. It compares two words of up to eight bits each and provides a LOW output when the two words match bit for bit. The expansion input IA=B also serves as an active LOW enable input.
s Compares two 8-bit words in ns typ s Expandable to any word length s 20-pin package
