www.DataSheet4U.com 54AC521 • 54ACT521 8-Bit Identity Comparator September 1998 54AC521 • 54ACT521 8-Bit Identity Comparator General Description 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 n n n n n n ICC reduced by 50% Compares two 8-bit words in 6.5 ns typ Expandable to any word length Outputs sour.
