6.5.1 DC Electrical Characteristics
(4.5V < VCC < 5.5V; 6V < VSUP < 18V; -40°C < TJ < 150°C, VBUS is the voltage on the LIN node. All voltages are with respect to ground (VSS);
positive current flows into the pin.

1. This failure condition triggers thermal shut down when shut down temperature threshold is exceeded.
2. Not production tested.
3. Vth_dom: Receiver threshold of the recessive to dominant LIN bus edge
Vth_rec : Receiver threshold of the dominant to recessive LIN bus edge
