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.
