Preliminary Technical Data

1Stresses 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 condition s above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability. Only one absolute maximum rating may be

applied at any one time.
