74AC520 • 74ACT520

8-Bit Identity Comparator

General Description

Features

■ Compares two 8-bit words in 6.5 ns typ

■ Expandable to any word length

■ 20-pin package

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 I_{A = B}also serves as an active LOW enable

■ Outputs source/sink 24 mA

■ ACT520 has TTL-compatible inputs

input.
