Overview
74FCT521AT/CT FAST CMOS 8-BIT IDENTITY COMPARATOR FAST CMOS 8-BIT IDENTITY COMPARATOR INDUSTRIALTEMPERATURERANGE 74FCT521AT/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.
