Note 4: Stresses greater than

those listed under “Absolute Maximum Ratings” may 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 may affect device reliability.
