Stresses beyond those listed under Absolute Maximum Rating may cause permanent damage to the device. These are stress

ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated

under Recommended Operating Condition. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.

(2)

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
