Can transceiver and method for the can transceiver

A controller area network, CAN, transceiver, comprising:

• a transmit data, TXD, interface, a receive data, RXD, interface, a CAN Bus interface, a transmitter, a receiver, a reducer, and a test unit,
• wherein a transmitter input of the transmitter is coupled to the TXD interface for receiving a TXD signal,
• wherein a transmitter output of the transmitter is coupled to a test unit input of the test unit and a first test unit output of the test unit is coupled to the CAN Bus interface,
• wherein the CAN Bus interface is coupled to a receiver input of the receiver via the reducer,
• wherein a receiver output of the receiver is coupled to the RXD interface,
• wherein a second test unit output of the test unit is coupled to the receiver input of the receiver,
• wherein the test unit is configured to change from a first state to a second state, and vice versa,
• wherein the test unit is configured, in the first state, to couple the test unit input to the first test unit output and to decouple the test unit input from the second test unit output, and
• wherein the test unit is configured, in the second state, to decouple the test unit input from the first test unit output and to couple the test unit input to the second test unit output.
