Notes 1. Where TA > +55

°C, perform derating at TJ MAX. 125°C, −5 mW/°C.

2. Where TA > +25

°C, perform derating at TJ MAX. 125°C, −4.4 mW/°C.

Caution If any of the parameters exceeds the absolute maximum ratings, even momentarily, the quality of

the product may be impaired.

The absolute maximum ratings are values that may physically

damage the product(s). Be sure to use the product(s) within the ratings.
