These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Expo- sure to Absolute Maximum Rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Specifications: Unless otherwise noted, TA = -40°C to +85°C. Typical values are at TA = +25°C.
