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.
