V CC pin can be greater or smaller than VLED; neither should go below GND. Caution: Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stre ss ratings only; functional operation of the device at these or any other conditions excee ding those indicated in this specification is not implied. Device reliability may be affected by exposure to absolute maximum rating conditions for extend ed periods of time. Semiconductor devices are ESD sensitive and may be damaged by expo sure to ESD events. Suitable ESD precautions should be taken when handling and transporting these devices
