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. Although the IXI858 / IXI859 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.
