Product details

5 Mbps CAN FD-ready transceiver for the automotive bus

It is part of the Automotive, AEC-Q100 series, so it carries the qualification and traceability expected for under-hood and chassis-domain deployments. The single driver and single receiver (1/1) handle the differential bus pair, and the 120 mV receiver hysteresis gives you a cleaner signal on a long or noisy twisted pair — useful when the harness runs across the vehicle.

For a BOM line going into a multi-year vehicle program, that removes the single-source-obsolescence risk you would carry with an NRND or EOL part.

Temperature range and package — field-fit for harsh spots

That covers engine bay, transmission, and exhaust-adjacent locations where the ambient is well above 85°C. The 14-VSON (4.5x3) package with wettable flank supports automated optical inspection (AOI) on the assembly line — a practical advantage for high-volume production where you want to verify every solder joint.

Frequently asked questions

Does TCAN1043HGDMTTQ1 support CAN FD and what is its maximum data rate?

Yes, the TCAN1043HGDMTTQ1 supports CAN FD with a maximum data rate of 5 Mbps. That is fast enough for the data phase of a CAN FD frame, which typically runs at 2 Mbps to 5 Mbps on the physical layer.

What is the difference between TCAN1043HGDMTTQ1 and TCAN1042?

The TCAN1043HGDMTTQ1 is a 5 Mbps CAN FD transceiver, while the TCAN1042 is typically a 1 Mbps or 2 Mbps classic CAN transceiver. The 1043 also includes the wettable-flank package option for AOI inspection, which the older 1042 may not offer in all variants. Both are AEC-Q100 qualified and share a similar pinout, but the 1043 is the higher-speed, newer-generation part.

Is TCAN1043HGDMTTQ1 compatible with 3.3V microcontrollers?

Its logic-level interface is 5 V tolerant, so you need level translation or a 5 V-tolerant MCU I/O if you are connecting to a 3.3 V microcontroller. A simple resistor divider or a 5 V-tolerant GPIO pin works for the TXD and RXD lines.
