Note 1. Stresses listed as the above Absolute Maximum Ratings may cause permanent damage to the device.  
These are for stress ratings. Functional operation of the device at these or any other conditions beyond  
those indicated in the operational sections of the specifications is not implied. Exposure to absolute  
maximum rating conditions for extended periods may remain possibility to affect device reliability.  
Note 2. Devices are ESD sensitive. Handling precaution recommended.  
Note 3. qJA is measured in the natural convection at TA = 25OC on a low effective thermal conductivity test board of  
JEDEC 51-7 thermal measurement standard.  
Note 4. The “case temperature” location for measuring θJC is on the top of the package.  
Note 5. The device is not guaranteed to function outside its operating conditions.
