54AC521 Description
The AC/ACT521 is an expandable 8-bit parator. It 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 IA = B also serves as an active LOW enable input.
54AC521 is 8-Bit Identity Comparator manufactured by National Semiconductor.
