Absolute Maximum Ratings
Subjecting the part to stresses beyond those listed under this section may cause permanent damage to the device.
These are stress ratings only and do not imply that the device functions beyond these ratings. Exposure to the
extremes of these conditions for extended periods may affect device reliability.
