Note (1): The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
The device should not be operated at these limits. The “Functional Specifications” table will define the conditions for actual
device operation. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.
