SN65HVD235QDRQ1 Typical Application
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 TXD and RXD pins. 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 TXD and RXD pins. See Figure 35 and Figure 36 .
Figure 35. Bus States (Physical Bit Representation)
Figure 36. 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 120Ω characteristic impedance twisted-pair cable with termination on both ends of the bus.
