Product specification
74F521
8-bit identity comparator
2
May 15, 1990
853–0372 99601
FEATURES
Compares two 8-bit words in 6.5ns typical
Expandable to any word length
DESCRIPTION
The 74F521 is an expandable 8-bit comparator. It compares two
words of up to 8 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.
