• Manufacturer Part Number: TH8061KDCA
• Description: Voltage Regulator with integrated LIN Transceiver
• Manufacturer: MELEXIS [Melexis Microelectronic Systems]

Input TxD
The 5V input TxD controls directly the BUS level:
The TxD pin has an internal pull up resistor connected to VCC. This guarantees that an open TxD pin
generates a recessive BUS level.
Output RxD
The received BUS signal will be output to the RxD pin:
This output is a push-pull driver between VCC and GND with an output current of 1mA.
