* Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress r ating only and

functional operation of the device at these or any other conditions above those indicated in the operating sections of this spec ification is not implied.

Exposure to absolute maximum rating conditions for extended periods may affect reliability.
