Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
bient thermal resistance), and T
given in the Absolute Maximum Ratings, which ever is lower.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
Note 4: Thermal Shutdown will protect the device from permanent damage.
