Note:
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 listed in the operational sections is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. T

= +25°C unless otherwise stated.
ESD SUSCEPTIBILITY
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 volts, which
readily accumulate on the human body and on test equipment, can discharge without detection.
Although this device features proprietary ESD protection circuitry, permanent damage may still occur
on this device if it is subjected to high energy electrostatic discharges. Therefore, proper precautions
are recommended to avoid any performance degradation or loss of functionality.
WARNING!
