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:Thermal Resistance is specified with approximately 1 square of 1 oz copper.

Note 3:Thermal Resistance is specified with the component mounted on a low effective thermal conductivity test

board in free air at TA=25°C.

Note 4:The device is not guaranteed to function outside its operating conditions.
