(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability.
(2) All voltages are with respect to network ground terminal.
(3) Limit the junction temperature to 105°C for continuous operation at maximum output power.
(4) Limit the junction temperature to 125°C for 5% duty cycle operation.
(5) In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (T_A(max)) is dependent on the maximum operating junction temperature (T_J(max)), the
maximum power dissipation of the device in the application (P_D(max)), and the junction-to-ambient thermal resistance of the part/package
in the application (θ_JA), as given by the following equation: T_A(max)= T_J(max)–(θ_JA X P_D(max)). To achieve optimum performance, it is
recommended to operate the device with a maximum junction temperature of 105°C.

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with
less than 500-V HBM is possible with the necessary precautions.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with
less than 250-V CDM is possible with the necessary precautions.
