74AC520 • 74ACT520 8-Bit Identity Comparator February 1989 Revised November 1999 74AC520 74ACT520 8-Bit Identity Comparator General Description Features The AC/ACT520 are expandable 8-bit comparators. TheyCompares two 8-bit words in 6.5 ns typ compare two words of up to eight bits each and provide aExpandable to any word length LOW output when the two words match bit for bit. The 20-pin package expansion input I also serves as an active LOW enable A = B Outputs source/sink 24 mA input.
