Product details

Active CAN FD transceiver for automotive and industrial bus nodes

The TCAN1043HGDQ1: The 14-SOIC package (3.90 mm width) fits standard CAN node footprints used in engine control units, body electronics, and industrial automation gateways.

5 Mbps data rate — CAN FD without the guesswork

The 5 Mbps data rate confirms CAN FD (flexible data-rate) support, doubling the payload per frame versus classical CAN and enabling faster firmware updates and higher-throughput sensor data on the bus. For a BOM that already specifies CAN FD controllers, this transceiver matches the physical-layer speed without needing a protocol bridge or a separate high-speed part.

AEC-Q100 and full temp range — built for harsh environments

Frequently asked questions

Does TCAN1043HGDQ1 support CAN FD?

Yes. The 5 Mbps data rate confirms CAN FD support, enabling the larger payload frames defined in the CAN FD protocol.

What is the closest pin-compatible alternative to TCAN1043HGDQ1?

Within the TCAN1043 family, the TCAN1042 is a lower-speed variant (classical CAN only, 1 Mbps). The TCAN1043 adds CAN FD support at 5 Mbps while maintaining the same 14-SOIC footprint and pinout, making it the drop-in upgrade for designs that need higher data throughput.

Is TCAN1043HGDQ1 RoHS compliant?

The part is listed as RoHS compliant per Texas Instruments' standard material declaration. The 14-SOIC package uses a nickel-palladium-gold (NiPdAu) lead finish, which is lead-free and RoHS-compatible.
