8-BIT IDENTITY COMPARATOR
The MC54/74F521 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 en-
able input.
Compares Two 8-Bit Words in 6.5 ns Typical
Expandable to Any Word Length
