Notes:
2. Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings
 
  only; functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied.
  Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time
 
3. The absolute maximum of 5V is a transient stress rating and is not meant as functional operating conditions. It is not recommended to operate the
 
  device at the absolute maximum rated conditions for any period of time.

 (2.5V to 3.6V) must be applied to be guaranteed for the output sampling.
 
The output state is valid after the second operating phase (typical 100ms).
