This is a stress rating only and the 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 max- imum rating conditions for extended periods may affect device reliability. DC OPERATING CHARACTERISTICS (Temperature = -40°C to +85°C, unless otherwise stated.)
