† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended periods may affect device reliability. Note: Transient junction temperatures should not exceed one second in duration. Sustained junction temperatures above +170°C may impact the device reliability. The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction to air (i.e., T_A, T_J, θJA). Exceeding the maximum allowable power dissipation may cause the device operating junction temperature to exceed the maximum +165°C rating. Sustained junction temperatures above +165°C can impact the device reliability.).
