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 indicated in the operational sec-

tions of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability. Absolute maximum ratings apply individually

only, not in combination. Unless otherwise specified, all other

voltages are referenced to GND.

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.
