(1) Stresses beyond those listed under the 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 the recommended
operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.
(3) Approaching the absolute maximum rating for the VIN pin may cause the voltage on the PH pin to exceed the absolute maximum rating.
