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.
