74AC520 - 8-Bit Identity Comparator

General 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.

Key Features

  • Compares two 8-bit words in 6.5ns typ.
  • Expandable to any word length.
  • 20-pin package.
  • Outputs source/sink 24mA.
  • ACT520 has TTL-compatible inputs tm General.
