RXD pin is an open-drain output.  In standby mode RXD is pulled low which has the device pulling current through VSUP through the pull-up resisitor to VCC.  The value of the pull-up resistor impacts the standby mode current.  A 10 kΩ resistor value can add as much as 500 µA of current.
Operational supply voltage and nominal supply voltage are in relationship to the LIN transceiver.  A VSUP above 28 V means the device will function but may not meet the rest of the parametric data while the nominal range means the device will meet the parametric data minus any differences provided in the test conditions.
