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 expansion input IA = B also serves as an active LOW enable input. n n n n n Expandable to any word length 20-pin package Outputs source/sink 24 mA ’ACT520 has TTL-compatible inputs Standard Microcircuit Drawing (SMD) 54AC520: 5962-90916 54ACT520: 5962-89793
