Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections

of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliabili ty.

* All voltages are with respect to VSS (GND).
