Ordering Information
Absolute Maximum Ratings
ESD Warning
ESD (electrostatic discharge) sensitive device. Electrostatic charges can readily accumulate on test equipment and the human body
in excess of 4000 Volts. This energy can discharge without detection. Although the IXS839/839A/839B feature proprietary ESD
protection circuitry, permanent damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

Absolute Maximum Ratings are stress ratings.
Stresses in excess of these ratings can cause
permanent damage to the device. Functional
operation of the device at these or any other
conditions beyond those indicated in the operational
sections of this data sheet is not implied. Exposure
of the device to the absolute maximum ratings for
an extended period may degrade the device and
affect its reliability.
