1 / 10 page 54AC520 • 54ACT520 8-Bit Identity Comparator General Description The ’AC/’ACT520 are expandable 8-bit comparators. They compare two words of up to eight bits each and provide a LOW output when the two words match bit for bit. The ex- pansion input I A = B also serves as an active LOW enable in- put. Features n Compares two 8-bit words in 6.5 ns typ n Expandable to any word length n 20-pin package n Outputs source/sink 24 mA n ’ACT520 has TTL-compatible inputs n Standard Microcircuit Drawing (SMD) 54AC520: 5962-90916 54ACT520: 5962-89793 Logic Symbols Pin Names Description A 0–A7 Word A Inputs B 0–B7 Word B Inputs T A = B Expansion or Enable Input O A = B Identity Output FACT™ is a trademark of Fairchild Semiconductor Corporation.
