9.3.10.4 Unpowered Devices

The device is designed to be an ideal passive or no load to the CAN bus if it is unpowered. The CANH and CANL pins have low leakage currents when the device is un-powered so they present no load to the bus. This is critical if some nodes of the network are unpowered while the rest of the of network remains in operation.

The logic terminals also have low leakage currents when the device is un-powered so they do not load down other circuits which may remain powered.
