Note 1: Stresses beyond the absolute maximum rating may damage the devic e and operating in the absolute
maximum rating conditions may affect device reliability.
Note 2: The maximum allowable power dissipation at any T_A (ambient temperature) is calculated using: P_D (max) =
(T_J – T_A) / θ_JA; T_J = 125°C. Exceeding the maximum allowable power dissipation will result in excessive die
temperature.
