Note A - 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.
