† Notice: Stresses above those listed under “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.
Note 1: Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5 k in series with
100 pF.
