(1) Stresses beyond those listed under Absolute Maximum Ratings 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 Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Power sequence must be followed as stated in the Power Supply Design section. Failure to follow the required power sequence may result in unwanted voltage on the VA1.8 pin that can exceed the absolute maximum voltage of 2.35 VDC.
(3) Prolonged use at this temperature may increase the device failure-in-time (FIT) rate.
