Note - The device is not guaranteed to function outside its operating rating. Stresses 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 outside
those listed in the operational sections of the specification is not implied. Exposure to any absolute maximum rating for extended periods may
affect device performance and reliability. Devices are ESD sensitive. Handling precautions are recommended.
