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

† 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 maxi-

mum rating conditions for extended periods may affect device reliability. Specifications are for packaged

product only.

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

Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable

junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the

maximum allowable power dissipation will cause the device operating junction temperature to exceed the

maximum +125°C rating. Sustained junction temperatures above +125°C can impact the device reliability.
