NOTES
*This is a stress rating only and functional operation of the device at these or any
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 the
device features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recom-
mended to avoid performance degradation or loss of functionality.
JA
other conditions above those indicated in the operation section of this specifi-
cation is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
JA
is specified for worst case conditions with device soldered on a circuit board.
