Electrical specification
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 section of this
document 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.
Where application information is given, it is advisory only and does not form part of the specification.

The product is not protected against overvoltage or reversed voltages. If necessary, voltage
spikes exceeding the power supply voltage specification, given in table above, must be limited
to values within the specified boundaries by using appropriate protection devices.
