Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.

Absolute maximum ratings are stress ratings only and functional device operation is not implied.

2. 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 under "recom-mended operating conditions" is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.
