Note 1: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 kΩ in series

with 100 pF.

† 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 con-

ditions 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 pack-

aged product only.

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