† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE: All voltage values, except differential I/O bus voltages, are stated with respect to the network ground terminal.

† The value of VREF may be selected to provide optimum noise margin in the system. Typically, the value of VREF is expected to be 0.5VDDQ of

the transmitting device and VREF is expected to track variations in VDDQ. Peak-to-peak ac noise on VREF may not exceed 2% of VREF (dc).
