74F521
8-Bit Identity Comparator
General Description
The 74F521 is an expandable 8-bit comparator. It com-
pares 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.
Features
s Compares two 8-bit words in 6.5 ns typ
s Expandable to any word length
s 20-pin package
