Electrical Requirements
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.
Absolute Maximum Rating
The limiting values given below are following the Absolute Maximum Rating System (IEC 134).
