Maximum Power Dissipation (PD(max)).................................................................................................................(Note 2)

† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability. Specifications are for packaged product only.

‡ Notice: The device is not guaranteed to function outside its operating ratings.

Note 1: Devices are ESD sensitive. Handling precautions are recommended.

2: PD(max) = (TJ(max) – TA) ÷ θJA, where θJA depends upon the printed circuit layout. See the

Application Information section.
