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 those limits within which the functionality of the device is

guaranteed.

☞ Electrical characteristics are defined according to the verification on a representative number of

samples or according to the simulation.

☞ Where application information is given, it is advisory only and does not form part of the

specification.

4.1 Absolute maximum rating

☞ Limiting values given below are in accordance with Absolute Maximum Rating System (IEC 134).
