Notes
1. For DIP14 packages: above 70 °C the value of PD derates linearly with 12 mW/K.
2. For SO14 packages: above 70 °C the value of PD derates linearly with 8 mW/K.
For (T)SSOP14 packages: above 60 °C the value of PD derates linearly with 5.5 mW/K.
For DHVQFN14 packages: above 60 °C the value of PD derates linearly with 4.5 mW/K.
