February 1989
Revised November 1999
74AC520 鈥?74ACT520
8-Bit Identity Comparator
General Description
The AC/ACT520 are expandable 8-bit comparators. They
compare two words of up to eight bits each and provide a
LOW output when the two words match bit for bit. The
expansion input I
A
=
B
also serves as an active LOW enable
input.
