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.","metaTitle":"TCAN1042HDR CAN Transceiver, 5 Mbps, 8-SOIC, Active","metaDescription":"Texas Instruments TCAN1042HDR CAN transceiver, 5 Mbps data rate, 4.5V-5.5V supply, -55°C to 125°C, 8-SOIC.
