September 1998
54FCT521
8-Bit Identity Comparator
General Description
The 鈥橣CT521 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 I
A = B
also serves as an active LOW enable input.
