 |  | The IDT54/74FCT521/A/B/C are 8-bit identity comparators 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 IA = B also serves as an active LOW enable input. |  |  Click here to download IDT74FCT521DB Datasheet*)
