1 / 6 page 1 IDT54/74FCT521/A/B/C FAST CMOS 8-BIT IDENTITY COMPARATOR MILITARYANDCOMMERCIALTEMPERATURERANGES JUNE 2000 1999 Integrated Device Technology, Inc. DSC-4617/2 c IDT54/74FCT521/A/B/C MILITARY AND COMMERCIAL TEMPERATURE RANGES 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 = B also serves as an active low enable input.
