DESCRIPTION:
The IDT54/74FCT521T/AT/BT/CT are 8-bit identity com-
parators built using an advanced dual metal CMOS technol-
ogy. 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.
