IDT74FCT521 General Description
DESCRIPTION:
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.
