Absolute Maximum Ratings*  
*NOTICE:  
Stresses beyond those listed under “Absolute  
Maximum Ratings” may cause permanent dam-  
age to the device. This is a stress rating only and  
functional operation of the device at these or any  
other conditions beyond those indicated in the  
operational sections of this specification is not  
implied. Exposure to absolute maximum rating  
conditions for extended periods may affect device  
reliability.
