The TCAN3403-Q1 and TCAN3404-Q1 are 3.3 V controller area network (CAN) FD transceivers that are compatible with the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification.

The transceivers have certified electromagnetic compatibility (EMC) operation for use with classical CAN and CAN FD networks up to 5 megabits per second (Mbps). Up to 8 Mbps operation in simpler networks is possible with these devices. The TCAN3403-Q1 includes an internal logic level translation through the VIO pin, allowing the direct interface of the transceiver I/Os to 1.8-V, 2.5-V, or 3.3-V logic levels. The TCAN3404-Q1 has shutdown feature where all blocks are powered off and device enters ultra-low power consumption mode. The transceivers support a low-power standby mode, and a wake over CAN which is compliant to the ISO 11898-2:2016 defined wake-up pattern (WUP).

The transceivers include thermal-shutdown (TSD), TXD-dominant time-out (DTO) and supply undervoltage detection. The devices have defined fail-safe behavior in supply undervoltage or floating pin scenarios. These devices are available in industry-standard SOIC-8, the VSON-8, and a space-saving small footprint SOT-23 packages.
