1. Vs not floating.

2. Related to the external supply pin of the CAN-transceiver. If the transceiver supply is generated entirely inside the device

the parameter is measured with respect to the supply of the device.

3. Related to the external supply pin of the CAN-transceiver. If the transceiver supply is generated entirely inside the device

the parameter is measured with respect to the supply of the device; if the transceiver is supplied by its own supply pin, this

pin has to fulfill this specification as well as the supply that is used to generate the transceiver voltage in case it is on the

same device.

Note:

The leakage currents have to be measured with the supply of the CAN-transceiver connected to ground either

directly or via 47 kΩ. If the CAN-transceiver supply is generated by the device from VS, VS has to be connected

to ground. If the CAN-transceiver is supplied by another device, the supply of the CAN-transceiver has to be

connected to ground.

LIN transceiver

LIN ISO 17987-4:2016 compliant for data rates up to 20 kBit/s

The voltages are referred to GND and currents are assumed positive, when the current flows into the pin.

6 V < VSREG < 18 V, TJ = -40 °C to 150 °C unless otherwise specified.
