The CAN bus has two states during powered operation of the device; dominant and recessive. A dominant bus state is when the bus is driven differentially, corresponding to a logic low on the D and R pin. A recessive bus state is when the bus is biased to VCC / 2 via the high-resistance internal resistors RIN and RID of the receiver, corresponding to a logic high on the D and R pins. See Figure 34 and Figure 35.

Simplified Recessive Common Mode Bias and Receiver These CAN transceivers are typically used in applications with a host microprocessor or FPGA that includes the link layer portion of the CAN protocol. The different nodes on the network are typically connected through the use of a 120-Ω characteristic impedance twisted-pair cable with termination on both ends of the bus.
