Hi Team,

Please provide the duplex of the part TCAN1145DMTRQ1, whether it is half/full duplex.

Provide the supporting document for explanation as well.

Thanks,

Hi Mahesh,

The CAN network is based on a half-duplex differential signal. CAN has a single sender with priority arbitration. If two or more nodes attempt to send simultaneously, any nodes transmitting a lower priority ID will stop transmitting during the arbitration phase.

I'm including some materials for learning CAN:

Mahesh,

CAN transceivers in general are half duplex. This is due to arbitration embedded in the CAN protocol where only one transceiver can be transmitting at a time while others attempt, and ultimately one transceiver will win priority and be transmitting. The CAN protocol isn't built to need a device transmitting and receiving different sets of data at the same time.

Eric Hackett
