DESCRIPTION:
The IDT74FCT521T is an 8-bit identity comparator built using an
advanced dual metal CMOS technology. These devices 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.
