Product details

At 5 Mbps the bit time is 200 ns. The transceiver propagation delay and loop delay must fit within the CAN controller's timing budget, especially when the bus length exceeds a few meters. For a 5 Mbps CAN FD network, keep the total cable length under 40 m to stay within the bit sampling window; the TCAN1042HDR's fast loop times support this without needing a slower data phase.

The 125°C ceiling means the transceiver can sit next to a hot microcontroller or power stage without derating the bus interface.

Frequently asked questions

What is the difference between TCAN1042 and TCAN1050?

The TCAN1042 supports data rates up to 5 Mbps for CAN FD, while the TCAN1050 is a classic CAN transceiver limited to 1 Mbps. Both are pin-compatible in the 8-SOIC package, so the TCAN1042 is the drop-in upgrade for networks that need the higher data phase.

Is TCAN1042HDR compatible with 3.3V logic?

Its logic input thresholds are 5V-level; for 3.3V microcontrollers, use a level shifter or a 3.3V-tolerant CAN transceiver variant.
