A.1.7 Operating Conditions
This chapter describes the operating conditions of the device. Unless otherwise noted those conditions
apply to all the following data.
NOTE:
Please refer to the temperature rating of the device (C) with regards to the ambient
temperature TA and the junction temperature TJ. For power dissipation
