4 Electrical specifications
⚠ 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 at any conditions other than those specified in the Operating Conditions sections (section
4.2) of the specification should be avoided. Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.
☞ Operating condition ranges define 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.
4.1 Absolute maximum rating
☞ Limit values given below are in accordance with the Absolute Maximum Rating System (IEC 134).
