I'm looking to use the SN65HVD230 CAN transceiver but had a question about the current consumption.
In table 8.3 Recommended Operating Conditions, it said the high level output current for the driver is -40mA and the low level output current is 48mA. However in Table 8.5, it is said that the supply current (Icc) has a max recommended current of 17mA. How can the driver current consumption be greater than the overall supply current ?
How do I calculate the overall current consumption of the bus ? The datasheet seems to only talk about the current consumption of the receiver and driver, but not the actual CANH and CANL lines?
