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 TA (ambient temperature) is calculated using: PD (max) =
(TJ – TA) / qJA; TJ = 125°C. Exceeding the maximum allowable power dissipation will result in excessive die
temperature.
