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 REXT and RSER plus Laser Diode should not be greater than 1V.

3. Still-air without heatsink.

4. RSET minimum 430Ω.

5. VIN = VIL (min).

6. IMOD = 25mA.
