18.1.5 Output Pin (LIN_RXD)
In Normal mode, this pin reports the state of the LIN bus to the microcontroller. LIN high (Recessive state) is indicated by a high level at LIN_RXD; LIN low (Dominant state) is indicated by a low level at LIN_RXD.
The output is an open-drain; therefore, it is compatible with a 3.3V or 5V power supply. The AC characteristics are defined by an external pull-up resistor of 4.7 kOhm to 5V and a load capacitor of 20 pF.
In Unpowered mode, LIN_RXD is switched off.
