performance.
Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated
by TJMAX, θJA,and the ambient temperature TA. The maximum allowable power dissipation is PDMAX
= (TJMAX - TA)/ θJA or thenumber given in Absolute Maximum Ratings, whichever is lower.
Note 3: Human body model, 100pF discharged through a 1.5kΩ resistor.
