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 the component mounted on a low effective thermal conductivity test board in free air at
