com 74AC521 • 74ACT521 8-Bit Identity Comparator November 1988 Revised March 2005 74AC521 • 74ACT521 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 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 source/sink 24 mA s ACT521 has TTL-compatible inputs Ordering Code: Order Number 74AC521SC 74AC521SJ 74AC521MTC 74AC521PC 74ACT521SC 74ACT521SJ 74ACT521MTC 74ACT521PC Package...
