74AC520, 74ACT520 8-Bit Identity Comparator

March 2007

74AC520, 74ACT520

8-Bit Identity Comparator

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

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 I

also serves as an active

LOW enable input.
