NOTE 1: The input voltage limits on PFI and WDI may be exceeded if the input current is limited to
less than 10mA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those indicated in the operational section s of the sp ecifica tions is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
