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.

FEATURES:

• IDT54/74FCT521 equivalent to FASTTM speed

• IDT54/74FCT521A 35 faster than FAST

• IDT54/74FCT521B 50 faster than FAST

• IDT54/74FCT521C 60 faster than FAST

• Equivalent to FAST output drive over full temperature and voltage supply extremes

• IOL = 48mA (commercial), and 32mA (military)

• CMOS power levels (1mW typ. static)

• TTL input and output level compatible

• CMOS output level compatible

• Substantially lower input current levels than FAST (5µA max.)

• Product available in Radiation Tolerant and Radiation Enhanced versions

• JEDEC standard pinout for DIP and LCC

• Military product compliant to MIL-STD-883, Class B
