IDT74FCT521 Description
The FCT521 is an 8-bit identity parator built using an advanced dual metal CMOS technology. These devices pare 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.
