74AC520, 74ACT520

8-Bit Identity Comparator

Features

General Description

■ Compares two 8-bit words in 6.5ns 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

LOW enable input.

also serves as an active

A = B

■ Outputs source/sink 24mA

■ ACT520 has TTL-compatible inputs
