Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.

Note: Maximum power dissipation is a function of T_J(MAX), θ_JA, and Ta. The maximum allowable power dissipation at
any allowable ambient temperature is P_D = (T_J(MAX) -Ta)/θ_JA. Operating at the absolute maximum T_J of 150°C
can affect reliability.
