2.1
A number of terms are defined in ISO-11898 that are
used to describe the electrical characteristics of a CAN
transceiver device. These terms and definitions are
summarized in this section.
2.1.1
V
wires CANL and CANH relative to ground of each
individual CAN node.
2.1.2
Boundary voltage levels of V
respect to ground, for which proper operation will occur,
if up to the maximum number of CAN nodes are
connected to the bus.
2.1.3
Capacitance seen between CANL and CANH during
the
disconnected from the bus (see Figure 2-1).
2.1.4
Resistance seen between CANL and CANH during the
recessive state when the CAN node is disconnected
from the bus (see Figure 2-1).
