Tstg Maximum storage temperature -65 150 °C
(1) Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
(2) For up to 4 outputs per device, add ±25mA for each additional output.
