8-Bit Identity Comparator

General Description

Features

The AC/ACT521 is an expandable 8-bit comparator. It com-

pares two words of up to eight bits each and provides a

LOW output when the two words match bit for bit. The

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

■ I_CCreduced by 50%

■ Compares two 8-bit words in 6.5 ns typ

■ Expandable to any word length

■ 20-pin package

input.

■ Outputs source/sink 24 mA

■ ACT521 has TTL-compatible inputs
