Notes:

5.

Stresses greater than those listed under “Absolute Maximum Ratings” can cause permanent damage to the device. These are stress ratings only, and

functional op

eration of the device at these or any other conditions beyond those indicated under “Recommended Operating Conditions” is not implied.

Exposure to “Absolute Maximum Ratings” for extended periods can affect device reliability.

6. Absolute maximum ratings indicate limits beyond which damage to the component can occur. Electrical specifications do not apply when operating the

device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(max), the junction-

to-

ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated

using: PD(max)=(TJ(max) -TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature.
