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) / θJA; TJ = 125°C. Exceeding the maximum allowable power dissipation will result in excessive die

temperature.
