74F521 - 8-bit identity comparator

Description

The 74F521 is an expandable 8-bit comparator.

It compares two words of up to 8 bits each and provides 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

  • Compares two 8-bit words in 6.5ns typical.
  • Expandable to any word length.
