SC is the current drawn by the VISOIN pin under the specified
When compared with a given tBIT_TXD, a measure of bit symmetry
from the TXD digital isolation channel and CAN transceiver
can be determined. See Figure 2 for level definitions.

fOSC is the carrier frequency of the isoPower dc-to-dc converter
that provides isolated power to the bus side.
tTXD_DOM
Wake-Up Pattern (WUP)
tTXD_DOM is the propagation delay from a low signal on TXD to
WUP is a remote transmitted pattern required to trigger low
speed data transmission by the CAN transceiver while in standby
mode. The pattern does not force the transceiver out of standby
mode.

tTXD_REC
tTXD_REC is the propagation delay from a high signal on TXD to
transition the bus to a recessive state.
tLOOP_FALL
tLOOP_FALL is the propagation delay of a low signal on the TXD
pin to the bus dominant and transitions low on the RXD pin.
