Absolute Maximum Ratings
Item | Symbol | Value | Unit |
Power supply voltage for logic | VDD | 0.3~4.8 | V |
Input voltage | Vin | VDD+0.3 | V |
Operating temperature | Topr | -20 to 70 | °C |
Storage temperature | Tstg | -30 to 80 | °C |
Note:
Note1: Absolute maximum rating is the limit value beyond which the IC maybe broken.
They do not assure operations.
Note2: Background color changes slightly depending on ambient temperature.
This Phenomenon is reversible.
Ta≦70℃: 75%RH max
Ta>70℃: absolute humidity must be lower than the humidity of 75%RH at 70℃
Note3: Ta at -30℃ will be <48hrs, at 80 ℃ will be <120hrs

Note1: Optical performance should be evaluated at Ta=25℃ only .If LED is driven by high current, high ambient temperature & humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical operating life time is estimated data.
