8.4.2 Receive Mode

The data signals from the BUS pin will be transferred continuously to the pin RX. Short spikes on the bus signal are suppressed by the

observed.

8.5 RX and TX Interface

Input TX.

The 5V input TX controls directly the BUS level. LIN Transmitter acts like a slew-controlled level shifter. A dominant state (low) on TX leads to the

generates a recessive BUS level.
