PRODUCTION DATA.
The Vref pin (pin 5) on the SN65HVD230 and SN65HVD231 is available as a VCC/2 voltage reference. This pin can be connected to the common mode point of a split termination to help further stabilize the common mode voltage of the bus. If the Vref pin is not used it may be left floating.
