TJA1441BTK/0Z - 5 Mbit/s CAN FD Transceiver | NXP
MPN: TJA1441BTK/0Z ✓ פעילTJA1441BTK/0Z סקירה
A CAN transceiver is an interface integrated circuit that converts logic-level signals from a CAN controller into differential bus signals and converts received differential bus levels back into controller-compatible logic. In the broader hierarchy, a CAN transceiver is a bus interface IC, a communications interface device, and a semiconductor. It supports the physical layer of Controller Area Network communication while the CAN controller handles frame construction, arbitration, error management, and higher-level protocols.
The TJA1441 family combines support for Classical CAN and CAN FD operation with a maximum CAN FD fast-phase data rate of 5 Mbit/s. Its Silent mode provides a way to place the transceiver into a state suitable for designs that require a disabled or low-impact CAN interface. The manufacturer also describes the TJA1441 as a potential simple replacement for established high-speed Classical CAN and CAN FD transceivers, helping simplify upgrades without changing the surrounding hardware or software architecture.
Technical design work centers on correct implementation of the CAN bus, termination, decoupling, and protection. Because the device interfaces to a two-wire differential network, both transmitters connected to the same bus must be able to dominate recessive bus states without destructive contention. PCB signal integrity is therefore important from the controller through the transceiver to the connector, particularly in industrial, automotive, and communication systems operating at longer cable lengths or higher data rates.
Typical uses include CAN FD gateways, industrial automation equipment, automotive body and comfort electronics, building-control systems, robotics, diagnostic equipment, and embedded control platforms. The 5 Mbit/s capability is useful when a CAN FD controller uses the faster data phase, while compatibility with Classical CAN supports mixed-speed network segments and incremental migration from conventional CAN systems.
When assigning PCB resources, use the manufacturer pin and package information for the exact ordering code, and place local input and output capacitors close to their associated pins. Keep the CANH and CANL routing compact and symmetrical, provide the specified common-mode choke and bus protection where required, and install the bus termination at the physical ends of the network rather than beside the transceiver.
This product page combines manufacturer interface and package information, verified source links, drop-in candidate details, comparison parameters, and practical CAN-bus design guidance. It also distinguishes verified replacements from alternatives that require footprint, logic, or firmware validation before use.

Industrial Automation CAN FD Networks
The TJA1441BTK/0Z fits industrial automation nodes that need CAN FD communication rates up to 5 Mbit/s while retaining compatibility with Classical CAN systems. It sits between the CAN controller and the two-wire CANH/CANL bus, converting controller logic into differential bus signals and returning received bus data to the controller. Silent mode can support node designs that need controlled bus participation during particular operating states. For a robust industrial implementation, use the manufacturer application circuit, place bypass components close to the device, protect the external bus against industrial transients, and verify the exact supply and temperature limits against the production requirements.
מומלץ
Automotive Body and Comfort Electronics
The TJA1441BTK/0Z is suitable for CAN FD-based body, comfort, and control modules that exchange data over a two-wire CAN bus. Its 5 Mbit/s fast-phase capability can improve command and diagnostic throughput when the connected controller supports CAN FD, while Classical CAN compatibility supports mixed network populations. The 8-HVSON package supports compact board layouts, but automotive production use requires the exact ordering code to carry the required qualification. Follow the NXP pin and application guidance, route CANH and CANL symmetrically, use the recommended protection network, and confirm AEC-Q100 status, temperature range, and supply limits for the selected variant.
מומלץ
CAN FD Gateways and Protocol Bridges
A CAN FD gateway or protocol bridge can use the TJA1441BTK/0Z as the physical-layer interface between its CAN controller and external two-wire network. Supporting rates up to 5 Mbit/s allows the bridge to handle the CAN FD fast phase while preserving operation with slower Classical CAN nodes. Silent mode is useful when a gateway must control its contribution to the bus during controlled states. The transceiver should be placed close to the controller and bus connector, with a compact and balanced CANH/CANL route. Confirm the controller's logic levels, interrupt behavior, standby requirements, and bus timing against the TJA1441 data sheet before releasing the PCB.
מומלץ
Robotics and Motion-Control Systems
The TJA1441BTK/0Z can provide the CAN physical layer for robot controllers, motor-control modules, and distributed automation nodes. Its support for CAN FD up to 5 Mbit/s is advantageous when the system exchanges commands, diagnostics, or sensor information across multiple nodes and needs faster phase timing than Classical CAN offers. Silent-mode control can assist with orderly bus participation in battery-powered mobile platforms. Designers should preserve a short return path, minimize connector-to-transceiver distance, and apply protection appropriate to the installation environment. The controller, termination strategy, common-mode filtering, and transceiver supply must be validated together to prevent reflections or bus errors.
מומלץ
Building-Control and HVAC Equipment
The TJA1441BTK/0Z suits building-control equipment, HVAC controllers, and room-monitoring modules that use CAN for distributed sensors and actuators. CAN FD operation up to 5 Mbit/s can support higher diagnostic and control-data throughput, while two-wire bus connectivity simplifies wiring over long building runs. The transceiver's Silent mode provides an additional bus-state control for systems that manage power or isolate inactive nodes. For dependable field operation, apply transient protection at accessible bus connectors, use the bus termination arrangement required by the network topology, and verify EMC requirements for the installation. Supply voltage and temperature limits must be checked from the manufacturer data sheet for each enclosure environment.
מומלץ
Diagnostic and Test Equipment
The TJA1441BTK/0Z can be used in diagnostic tools, bus analyzers, and automated test fixtures that need to participate in CAN FD networks at rates up to 5 Mbit/s. The physical-layer interface allows a controller to exchange frames with existing equipment over a two-wire bus, making it suitable for benchtop and embedded test platforms. Silent mode is useful during controlled connection or isolation scenarios. Designers should account for connector reflections, cable length, termination, and the electrical state of unused nodes. Use the NXP application guidance to select protection and common-mode components, and confirm that the host controller supports the required CAN FD timing and error-handling behavior.

הערות תכנון
Route CANH and CANL as a closely coupled differential pair from the transceiver toward the bus connector. Minimize stub lengths, vias, unprotected copper exposure, and the distance between the transceiver and common-mode or protection components. Keep the return path continuous and use the manufacturer's recommended placement around the package. These practices reduce reflections and improve robustness in CAN FD systems operating up to 5 Mbit/s.
Do not assume that a CAN transceiver with the same family name has an interchangeable pinout. Verify the exact TJA1441 ordering code against the NXP package drawing and pin-description table, especially when changing between TJA1441 and TJA1442 variants or moving between 8-HVSON and other package options. Check Silent-mode polarity, supply voltage, timing, and transceiver behavior before treating a candidate as a board-level replacement.
Place local decoupling capacitors and the recommended bus-interface components close to their associated TJA1441BTK/0Z pins using the NXP application diagram as the reference. Keep the CAN bus connector and protection network outside the high-speed signal path, and provide bus termination only at the intended physical endpoints of the network. Review the assembled layout for accidental antenna-like copper and confirm that thermal and grounding arrangements follow the package documentation.
