Note 4.
Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical speci?cations do not apply when
operating the device outside of its operating ratings. The maximum allowable power dissipation is a function of the maximum junction tempera-
ture, T J(max) , the junction-to-ambient thermal resistance, θ JA , and the ambient temperature, T A .
The device is not guaranteed to function outside its operating rating.
Devices are ESD sensitive. Handling precautions recommended.
See application information for limitations on maximum operating frequency.
