Note 1:

Devices are ESD-sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series

with 100 pF.

2:

PD(MAX) = (TJ(MAX) – TA)/JA, where JA depends upon the printed circuit layout.

† 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.

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