Dtransceiver.rst13 A CAN transceiver is an external device that converts the logic level signals
14 from the CAN controller to the bus-levels. The bus lines are called
15 CAN High (CAN H) and CAN Low (CAN L).
18 These wires use the logic levels whereas the bus-level is interpreted
22 the same voltage level. This state is also the idle state.
23 To write a dominant bit to the bus, open-drain transistors tie CAN H to Vdd
25 The first and last node use a 120-ohm resistor between CAN H and CAN L to
27 This structure is called a wired-AND.
