IDT74FCT521AT/CT

FAST CMOS 8-BIT IDENTITY COMPARATOR

INDUSTRIAL TEMPERATURE RANGE

FAST CMOS 8-BIT

IDENTITY COMPARATOR

IDT74FCT521AT/CT

FEATURES:

•

A and C grades

Low input and output leakage

≤

1µA (max.)

CMOS power levels

True TTL input and output compatibility:

– V

= 3.3V (typ.)

– V

= 0.3V (typ.)

High Drive outputs (-15mA I

, 48mA I

)

Meets or exceeds JEDEC standard 18 specifications

Power off disable outputs permit "live insertion"

Available in SOIC, SSOP, 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

also serves as an active low

enable input.
