Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable

maximum allowable power dissipation will cause the device operating junction temperature to exceed the

maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
