Output Current ............................................. 5mA Lead Temperature (Soldering, 10 seconds) .............................. 300 °C *COMMENT Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. 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 maximum rating condi- tions for extended periods may affect device reliability. RECOMMENDED OPERATING CONDITIONS Temperature Min. Max.
