Notes:
1. Permanent device damage may occur if Absolute Maximum Ratings are exceeded. This is a stress rating only and functional operation is not implied
at conditions other than those detailed in the operational sections of this data sheet. Exposure to Absolute Maximum Ratings conditions for extended
periods may affect device reliability.
2. The voltage drop across R EXT and R SER plus Laser Diode should not be greater than 1V.
3. Still-air without heatsink.
4. R SET minimum 430 ? .
5. V IN = V IL (min).
6. I MOD = 25mA.
