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
