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 spec- ification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. DC OPERATING CHARACTERISTICS (Temperature = -40°C to +85°C, unless otherwise stated.)
