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 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 pro-

prietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electro-

static discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or

loss of functionality.
