IDT74FCT521L

FAST的CMOS 8位身份比较器 FAST CMOS 8-BIT IDENTITY COMPARATOR

DESCRIPTION:

The FCT521 is an 8-bit identity comparator 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 = Balso serves as an active low enable input.
