Absolute Maximum Ratings
The following table shows the absolute maximum ratings of the device. These are stress ratings
only. Stresses beyond absolute maximum ratings may cause permanent damage to the device. Note
that the device is not guaranteed to operate properly at the maximum ratings. Exposure to the
absolute maximum rating conditions for extended periods may affect device reliability.
