The AC/ACT521 is an expandable 8-bit comparator. It compares two words of up to eight 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 s ICC reduced by 50% s Compares two 8-bit words in 6.5 ns typ s Expandable to any word length s 20-pin package s Outputs s.
