† _{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 6: All voltage values, except differential I/O bus voltages, are with respect to network ground terminal.

NOTE: Unused inputs that do not hold an integrated pullup or pulldown circuit need to be terminated either to VDDQ or GND, respectively, to avoid
excessive currents and lifetime degradation.
