8-BIT IDENTITY  
COMPARATOR  
The MC74AC521/74ACT521 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 I  
active LOW enable input.  
also serves as an  
A=B  
Compares Two 8-Bit Words in 6.5 ns Typ  
Expandable to Any Word Length  
20-Pin Package  
Outputs Source/Sink 24 mA
