* Stresses above those listed under "Absolute Maximum Ratings" may cause permanent

damage to the device. This a stress rating only. Functional operation of the device at these

or any other condition above those indicated in the operation sections of this specification, is

not implied. Exposure to Absolute Maximum Ratings for extended periods may affect device

reliability.

Note 1: A diode is internally connected between this pin and V

limited to 300µA max, no damage will occur.
