open-in-new Find other CAN & LIN transceivers & SBCs


The TCAN1046V-Q1 and TCAN1048V-Q1 (TCAN104xV) are dual, high-speed controller area network (CAN) transceivers that meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification.

The TCAN104xV-Q1 transceivers support both classical CAN and CAN FD networks up to 5 megabits per second (Mbps). The TCAN104xV includes internal logic level translation via the VIO terminal to allow for interfacing the transceiver IOs directly to 1.8-V, 2.5-V, 3.3-V, or 5-V logic IOs. The two CAN channels support independent mode control through the standby pins. This provides the ability to place each transceiver into its low-power state, standby mode, without impacting the state of the other CAN channel. While in standby mode the TCAN104xV supports remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP). The TCAN104xV transceivers also include many protection and diagnostic features including thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply under-voltage detection, and bus fault protection up to ±58 V.
