74FCT521CT - FAST CMOS 8-BIT IDENTITY COMPARATOR

Download the 74FCT521CT datasheet PDF. This datasheet also covers the 74FCT521AT variant, as both devices belong to the same fast cmos 8-bit identity comparator family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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.
