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.

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.
