TCAN1042HD - 2 Mbps Fault-Protected CAN FD | Texas Instruments
N.º de pieza: TCAN1042HD ✓ ActivoTCAN1042HD Descripción general
A CAN transceiver is the physical-layer interface between a CAN controller and a differential CAN bus. It converts logic-level TXD and RXD signals into CAN bus levels and back again. Within the hierarchy of automotive communication ICs, a CAN transceiver is a network interface transceiver, a bus-interface IC, and ultimately a semiconductor. Fault protection adds the ability to survive specified bus faults without permanent damage.
The TCAN1042HD provides classic CAN operation together with CAN FD support up to 2 Mbps. Its single-driver, single-receiver organization is suitable for a conventional CAN node rather than a multi-node bus interface. The 4.5 V to 5.5 V supply range supports regulated 5 V systems, while the -55°C to +125°C rating covers demanding automotive temperature ranges. Its 8-pin SOIC package supports conventional surface-mount assembly.
The transceiver provides a defined interface between a CAN controller and the differential CANH and CANL conductors. The TXD input accepts controller-generated logic, while RXD presents a logic-level receive signal to the controller. Fault-protected operation is important when the bus may be exposed to short circuits, abnormal voltage conditions, or other faults. ISO 11898-2:2016 physical-layer compliance is specifically identified for this device family.
Typical uses include automotive body and powertrain electronics, industrial automation controllers, robotics, building automation, and embedded CAN gateways. A controller such as a CAN FD-capable microcontroller can use the TCAN1042HD for the physical network connection, while external bus protection and filtering may be added where the cable length, topology, or electromagnetic environment requires it.
PCB design should keep the CANH and CANL route as a closely coupled differential pair and minimize the area between their return paths. Place transceiver and termination components near the connector or bus-entry point, observe the manufacturer’s grounding and supply-decoupling recommendations, and verify that the controller interface voltage levels match the transceiver logic requirements.
This product page combines the device specifications, package and lifecycle information, sourcing workflow, same-family drop-in alternatives, and practical CAN-interface design guidance. It is intended to help engineers identify the correct device and plan a robust PCB implementation without relying solely on a basic distributor listing.

Aplicaciones típicas
TCAN1042HD es adecuado para 6 aplicacións: Automotive Body Control Modules, Industrial PLC CAN Modules, Robotics and Motion-Control Networks, Building Automation Gateways, EV Charging and Energy Equipment, CAN-to-Ethernet Gateways.
Automotive Body Control Modules
The TCAN1042HD fits an automotive body-control CAN node that requires a 5 V supply, operation across -55°C to +125°C, and fault-protected bus interfacing. It converts the controller’s TXD and RXD signals into differential CANH and CANL levels while supporting classic CAN and CAN FD up to 2 Mbps. Place the transceiver near the vehicle network connector, use a tightly coupled differential route, and add appropriate external bus protection when the harness exposes the node to automotive transients.
Industrial PLC CAN Modules
The TCAN1042HD is suitable for PLC and industrial controller modules operating on a 4.5 V to 5.5 V supply. Its 2 Mbps CAN FD capability provides headroom for automation networks carrying motion commands, sensor data, and machine status, while fault protection improves resilience in electrically noisy equipment. The 8-SOIC package simplifies conventional surface-mount assembly, and the differential CANH/CANL routing should remain short and symmetrical between the transceiver, protection network, and bus connector.
Robotics and Motion-Control Networks
Robots can use the TCAN1042HD to connect a motion controller or embedded processor to distributed actuator and sensor nodes over CAN. The device supports classic CAN and 2 Mbps CAN FD, allowing the designer to select a higher throughput mode where bus timing and cable length permit it. Its single-driver, single-receiver architecture suits one CAN node per package. Firmware should enable CAN FD only when the complete network, including termination and transceiver timing, is designed for that rate.
Building Automation Gateways
The TCAN1042HD can interface building HVAC controllers, lighting controllers, access equipment, and energy-management gateways with a CAN-based supervisory bus. The 4.5 V to 5.5 V operating range fits common 5 V embedded systems, and the -55°C to +125°C rating supports wide environmental deployment. Fault-protected operation is valuable in installations where wiring faults or marginal cables may occur. Use proper termination only at designated bus endpoints and maintain a continuous differential return path beneath the CANH and CANL traces.
EV Charging and Energy Equipment
Electric-vehicle charging controllers and distributed energy equipment can use the TCAN1042HD for internal CAN communication between a supervisory controller, battery-management subsystem, and power-conversion module. Supporting 2 Mbps CAN FD allows the bus to carry command, status, and diagnostic information while the fault-protected transceiver protects the interface from abnormal bus conditions. External surge protection remains important because the transceiver alone is not a substitute for correctly rated automotive or industrial network protection.
CAN-to-Ethernet Gateways
A CAN-to-Ethernet gateway can use the TCAN1042HD as the physical-layer endpoint for an industrial or commercial CAN network. The transceiver supports classic CAN and CAN FD up to 2 Mbps, while its compact 8-SOIC package suits space-constrained embedded gateways. Separate the high-speed Ethernet section from the CAN interface, provide local supply decoupling, and route CANH and CANL as a coupled pair. Firmware must account for CAN FD frame formats when bridging traffic to classic CAN devices.

Diferenciadores clave

- No level-shifting supply required for the standard interface (frente a TCAN1042HV)
- Compact 8-SOIC implementation with one CAN node per device (frente a TCAN1042H)
Notas de diseño
Route CANH and CANL as a short, tightly coupled differential pair with a continuous reference plane below them. Keep the pair away from switching nodes and high-current return paths, avoid plane splits beneath the bus traces, and minimize stub branches. Place the termination network at the physical endpoints of the bus rather than adding it directly beside every transceiver.
Place the transceiver supply-decoupling capacitor close to VCC and the ground terminal, with a short, low-impedance connection to the ground plane. Follow the manufacturer’s recommended capacitor values and layout. If VIO level shifting is used in a related family member, treat VIO as a separately decoupled rail and verify its voltage before enabling the CAN interface.
Do not select a 5 Mbps G-suffix device merely because it shares the 8-SOIC footprint. The maximum CAN FD rate also depends on controller timing, bus length, termination, topology, and electromagnetic conditions. Likewise, confirm every unused or formerly split terminal before replacing a classic transceiver because newer devices may assign that terminal differently.
Use the shortest practical connection from the transceiver to the network entry point and position any common-mode choke, surge protection, or split termination according to the complete bus-protection strategy. Validate EMC performance at the final cable and enclosure level, since connector placement, ground bonding, and external protection components can affect radiated and immunity performance as much as the transceiver selection.
Información de cumplimiento
