Bus systems in automotive have to deal with ground-offsets between the various nodes. This means that
each node can "see" different single-ended bus voltages on the bus lines according to their own ground
level, whereas the differential bus voltage remains unaffected.
According to the data sheet of the TJA1050 [3] the maximum allowable single-ended voltage of CANH is
+12V, while the maximum allowable single-ended voltage of CANL is -12V. With single-ended bus
voltages within this range, it is guaranteed that the differential receiver threshold voltage lies between 0.5
and 0.9V. The allowable single-ended voltage range is known as the common mode range of the
differential receiver. ISO11898 calls for a common mode range from -2V to +7V. So, the TJA1050
provides an extended common mode range with respect to ISO11898.
Slightly exceeding the specified common mode range does not lead immediately to communication
failures, but significant exceeding has to be avoided. Thus, there is a limitation for tolerable ground-offsets.
The relation between the common mode range and the maximum allowable ground-offset is illustrated in
Figure 6.1 and 6.2.
Figure 6.1 shows the case where the ground level of a transmitting node 2 lies above that of a receiving
node 1. In this case the maximum allowable ground-offset corresponds to the maximum single-ended
voltage of 12V for CANH with respect to the ground level of the receiving node. The maximum allowable
ground-offset can be derived from Figure 6.1 to be 8V (GND

Figure 6.2 shows the case where the ground level of the sending node 1 lies below that of the receiving
node 2. In this case the maximum allowable ground-offset corresponds to the minimum single-ended
voltage of -12V for CANL with respect to the ground level of the receiving node 2. The maximum
