DESCRIPTION:

The IDT54/74FCT521T/AT/BT/CT 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:

? Std., A, B and C speed grades

? Low input and output leakage ≤1μA (max.)

? CMOS power levels

? True TTL input and output compatibility

– VOH = 3.3V (typ.)

– VOL = 0.3V (typ.)

? High drive outputs (-15mA IOH, 48mA IOL)

? Meets or exceeds JEDEC standard 18 specifications

? Product available in Radiation Tolerant and Radiation Enhanced versions

? Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked)

? Available in DIP, SOIC, SSOP, QSOP, CERPACK and LCC packages
