EQUIREMENTS
Stressing the device above one or more of the ratings listed in the Absolute Maximum Rating section may cause
permanent damage. These are stress ratings only. Operating the module at these or any conditions other than those
specified in the Operating Conditions sections of the specification should be avoided. Exposure to Absolute
Maximum Rating conditions for extended periods may affect device reliability.
The operating condition range defines those limits within which the functionality of the device is guaranteed. Where
application information is given, it is advisory only and does not form part of the specification.
