Stresses beyond 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 in the operational sections of the specifications is not implied. Exposure to absolute maximum

rating conditions for extended periods may affect device reliability.
