NOTE:

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 Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated

conditions for extended periods may affect device reliability.
