Absolute Maximum Ratings (Note)  
If Military/Aerospace specified devices are required,  
please contact the National Semiconductor Sales  
Office/Distributors for availability and specifications.  
Note: The ‘‘Absolute Maximum Ratings’’ are those values  
beyond which the safety of the device cannot be guaran-  
teed. The device should not be operated at these limits. The  
parametric values defined in the ‘‘Electrical Characteristics’’  
table are not guaranteed at the absolute maximum ratings.  
The ‘‘Recommended Operating Conditions’’ table will define  
the conditions for actual operation.
