Caution
Exposing the device to stress above those listed in Absolute Maximum Ratings could cause
permanent damage. The device is not meant to be operated under conditions outside the limits
described in the operational section of this specification. Exposure to Absolute Maximum Rating
conditions for extended periods may affect device reliability.
