Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

VLED refers to the maximum voltage drop across the external LED (at maximum LED current). This value is usually governed by the

forward drop voltage (VFB) of the LED.
