Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
The connection circuitry always regulates its output to a higher may cause permanent damage to the device. Exposure to any Absolute voltage than its input. The magnitude of this offset voltage as a function of Maximum Rating condition for extended periods may affect device the pull-up resistor and VCC voltage is shown in the Typical Performance reliability and lifetime.
