IDT74FCT521AT/CT FAST CMOS 8-BIT IDENTITY COMPARATOR FAST CMOS 8-BIT IDENTITY COMPARATOR INDUSTRIALTEMPERATURERANGE IDT74FCT521AT/CT FEATURES: A and C 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 Power off disable outputs permit "live insertion" Available in SOIC and QSOP packages DESCRIPTION: The IDT74FCT521T 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.
