IDT54FCT521BT

FAST CMOS 8-BIT IDENTITY COMPARATOR Integrated Device Technology, Inc. IDT54/74FCT521T IDT54/74FCT521AT IDT54/74FCT521BT IDT54/74FCT521CT 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 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.
