Absolute maximum ratings

Note:

Absolute maximum ratings are those values beyond which damage to the device may occur.

These are stress ratings only and functional operation of the device at these conditions is

not implied. Operating outside maximum recommended conditions for extended periods of

time may impact product reliability and results in device failures.
