Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress rat-

ing only; functional operation of the device at these or any

other conditions above those listed in the operational sections

of this specification is not implied. Exposure to absolute maxi-

mum rating conditions for extended periods may affect device

reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the

human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.
