Notes: 5. 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
6. The absolute maximum V
DD
of 6V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to
operate the device at the absolute maximum rated conditions for any period of time.

Notes: 7. BSEL pin internal pull-up resistor is only active during AWAKE time.
8. When power is initially on, the operating V
DD
(1.6V to 3.6V) must be applied to guarantee the output sampling.
The output state is valid after the second operating phase (typical 100ms).
9. Transition time varies dependant on the timing of BSEL activation during the sleep and awake phases.
