2.5V ≤ Vcc ≤ 5.5V

Notes:

. Vcc must be always higher than LED pin voltage (Vled)

2. After 4s at 500 (700) mA current

3. Iled variations per volt Vcc change

4. Iled variations at Vled change from to 2.5V

5. 5% change of Iled compared with Iled value at Vled = V

6. Iled settles 50µs later after CTRL from LOW to HIGH or from HIGH to LOW

7. Logic HIGH level should never exceed Vcc voltage

These are stress ratings only and

functional operation of the device at

these ratings or any other above those

indicated in the operation sections of

the specifications below is not implied.

Exposure to absolute maximum rating

conditions for extended periods of time

may affect reliability.
