DM74ALS520 DM74ALS521  
8-Bit Comparator  
General Description  
Features  
These comparators perform an “equal to” comparison of  
two 8-bit words with provision for expansion or external  
enabling. The matching of the two 8-bit input plus a logic  
LOW on the EN input produces the output A = B on the  
DM74ALS520 and DM74ALS521. The DM74ALS520 and  
DM74ALS521 have totem pole outputs for wire AND cas-  
cading. Additionally, the DM74ALS520 is provided with B  
input pull up termination resistors for analog or switch data.  
Switching specifications at 50 pF  
Switching specifications guaranteed over full tempera-  
ture and VCC range  
Advanced oxide-isolated, ion-implanted Schottky TTL  
process  
Functionally and pin for pin compatible with LS family  
counterpart  
Improved output transient handling capability
