Absolute maximum ratings
Stressing the device above the ratings listed in Table 3. Absolute maximum ratings may cause permanent
damage to the device. These are stress ratings only and operation of the device at these or any other conditions
above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum
rating conditions may affect device reliability.
