Stresses above those listed under Absolute Maximum Ratings

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

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

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum 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.
