Notes:

4. Stresses greater than those listed under Absolute Maximum Ratings can cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied.

Exposure to Absolute Maximum Ratings for extended periods can affect device reliability.

5. RθJA and RθJC are measured at TA = +25°C on a high effective thermal conductivity four-layer test board per JEDEC 51-7.
