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. Device mounted on 1"×1" FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.
