Notes:

1. Exceeding the absolute maximum rating may damage the device.

2. The device is not guaranteed to function outside its operating rating.

3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5kΩ in series with 100pF.

4. As determined by average current of all channels in use and all channels loaded.

5. The current through each LED meets the stated limits from the average current of all LEDs.
