• Stresses above those listed under" Absolute Maximum Ratings" may cause permanent dam-
age 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 af-
fect device reliability.
