8-Bit Identity Comparator
-The MC74AC521/74ACT521 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. Compares Two 8-Bit Words in 6.5 ns Typ Expandable to Any Word Length 20-Pin Package Outputs Source/Sink 24 mA ′ACT521 has TTL-Compatible Inputs
