54ACT520 - 8-Bit Identity Comparator

This page provides the datasheet information for the 54ACT520, a member of the 54AC520 8-Bit Identity Comparator family.

Description

The ’AC/’ACT520 are expandable 8-bit comparators.

They 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.

Features

  • n Compares two 8-bit words in 6.5 ns typ Logic Symbols IEEE/IEC DS100234-1 DS100234-4 Pin Names A0.
  • A7 B0.
  • B7 TA = B OA = B.
