IDT74FCT521A - FAST CMOS 8-BIT IDENTITY COMPARATOR

Download the IDT74FCT521A datasheet PDF. This datasheet also covers the IDT74FCT521 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 FCT521 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

  • IDT54/74FCT521 equivalent to FASTTM speed.
  • IDT54/74FCT521A 35% faster than FAST.
  • IDT54/74FCT521B 50% faster than FAST.
  • IDT54/74FCT521C 60% faster than FAST.
  • Equivalent to FAST output drive over full temperature and voltage supply extremes.
  • IOL = 48mA (commercial), and 32mA (military).
  • CMOS power levels (1mW typ. static).
  • TTL input and output level compatible.
  • CMOS output level compatible.
  • Substantially lo.
