Note:

6. For correct operation, SGND and PGND should always be connected together.

Caution:

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;

functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied.

Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.
