CAN J1939:

CAN bus uses two dedicated wires for communication. The wires are called CAN high and CAN low. When the CAN bus is in idle mode, both lines carry 2.5V. When data bits are being transmitted, the CAN high line goes to 3.75V and the CAN low drops to 1.25V, thereby generating a 2.5V differential between the lines. Since communication relies on a voltage differential between the two bus lines, the CAN bus is NOT sensitive to inductive spikes, electrical fields or other noise.

J1708:

The J1708 bus consists of two wires (A and B) with at least one twist (360°) per inch (2.54 cm) and a total length of up to 40 m. The voltage level on the bus is determined by the difference in voltage potential between wires “A” and “B”. A logical high level (1) is achieved when point A is at least 200 mV more positive than point B. A logical low level (0) means that point A is at least 200 mV more negative than point B (See the following figure). The transceiver should be fed with +6V to (-6V) in relation to common ground (common for all devices).
