TJA1441DT/0Z - 5 Mbit/s CAN FD Transceiver | NXP
料号： TJA1441DT/0Z ✓ 量产中TJA1441DT/0Z 概述
The TJA1441 belongs to the NXP TJA144x family of CAN transceivers. This family provides the physical-layer interface between a CAN controller and the differential CAN bus, allowing a host processor or dedicated CAN controller to exchange frames with other nodes. The family includes single-channel devices such as the TJA1441, TJA1442 and TJA1443, as well as the dual-channel TJA1448. Supporting CAN FD enables the transceiver to participate in networks carrying larger payloads and higher data rates than Classical CAN.
The TJA1441DT/0Z includes selectable operating behavior described in the manufacturer documentation as Silent mode and selectable Off mode. These functions are useful in automotive and industrial CAN networks where a node may need to reduce bus activity, enter a low-power state, or control when its transmitter is connected to the bus. The transceiver also supports fault-tolerant CAN bus operation, an important characteristic for systems exposed to wiring faults, shorts, or excessive bus loading.
Typical applications include electronic control units, body and chassis controllers, gateway modules, instrumentation, industrial automation equipment, diagnostic tools and CAN FD gateways. In these systems, the transceiver translates the controller's TXD logic signal into the differential CANH and CANL bus levels and converts received bus activity into an RXD signal for the controller.
For PCB layout, place the transceiver close to the CAN connector or bus-header interface and keep the CANH and CANL routing symmetrical. Provide a solid ground-plane connection and follow the decoupling recommendations in the manufacturer datasheet. The bus network must also satisfy the termination, cable-length and topology requirements for the selected CAN communication standard.
This product page combines the NXP family description, verified distributor identifiers, package information, replacement guidance and application-specific design considerations. It also provides drop-in alternatives identified from the available cross-reference information, allowing engineers to compare same-package candidates before changing an existing design.

典型应用
TJA1441DT/0Z 适用于 6 应用s: Automotive Electronic Control Units, CAN FD Automotive Gateways, Industrial CAN Automation Controllers, Vehicle Diagnostics and Test Equipment, Body and Chassis Control Modules, CAN FD Communication Hubs.
Automotive Electronic Control Units
The TJA1441DT/0Z fits automotive electronic control units that exchange controller-area-network data with body, chassis and powertrain modules. Its AEC-Q100 qualification, 4.5 V to 5.5 V supply range and CAN FD operation up to 5 Mbit/s support modern vehicle networks carrying larger payloads than Classical CAN. The transceiver provides normal, Silent and selectable Off operating modes, allowing a controller to manage bus participation and low-power states. Place it beside the CAN bus connector, route CANH and CANL as a balanced pair, and follow NXP's recommended grounding and termination arrangement.
推荐
CAN FD Automotive Gateways
The TJA1441DT/0Z is appropriate for gateway modules that translate between CAN FD and other vehicle network interfaces. Supporting rates up to 5 Mbit/s allows the gateway to sustain CAN FD traffic while its host processor handles routing and protocol conversion. Silent mode can support controlled bus participation, and selectable Off mode provides another network-state option. The 8-pin SO package supports compact controller layouts, but the designer must preserve the manufacturer's recommended pin assignments and provide stable 5 V regulation with effective local decoupling.
推荐
Industrial CAN Automation Controllers
The TJA1441DT/0Z can interface industrial automation controllers, remote I/O stations and machine-control modules with CAN FD-capable equipment. Its 5 Mbit/s maximum rate improves update throughput compared with Classical CAN, while Silent mode helps manage communication behavior during selected operating states. The device's 4.5 V to 5.5 V operating range is suitable for regulated industrial 5 V rails. Implement the bus network according to CAN topology and termination requirements, and route the differential bus pair away from switching nodes and high-current paths to preserve signal quality.
推荐
Vehicle Diagnostics and Test Equipment
The TJA1441DT/0Z is suitable for diagnostic interfaces and bench-test equipment that must connect an embedded controller to a CAN FD network. The transceiver's controller-side TXD and RXD signals fit a conventional CAN-controller arrangement, while Silent mode permits diagnostic activity without immediately driving the bus. CAN FD support up to 5 Mbit/s allows the equipment to validate modern network behavior as well as Classical CAN traffic. Designers should check controller timing, bus termination and the exact device configuration before releasing the test fixture.
推荐
Body and Chassis Control Modules
The TJA1441DT/0Z fits body and chassis control modules requiring a robust physical interface between a microcontroller and a two-wire CAN bus. CAN FD can reduce the number of frames needed for multi-sensor status information, improving network utilization without changing the transceiver's operating-voltage class. The selectable operating modes help software manage participation and shutdown behavior. Use a short, symmetrical CANH/CANL route, provide a continuous ground reference and observe the manufacturer's bus-fault and decoupling recommendations for production reliability.
推荐
CAN FD Communication Hubs
The TJA1441DT/0Z can be used in communication hubs and protocol adapters that need a standard CAN physical-layer interface. A 5 Mbit/s CAN FD capable channel supports efficient transfer of control and diagnostic data between nodes, while normal and Silent modes allow operating strategies appropriate to network management. The 8-pin SO format can simplify board-level integration where space is constrained. Confirm the hub architecture's bus-segment requirements, termination strategy and transceiver mode controls against the NXP datasheet before using the device in a multi-segment network.

关键差异点
- Adds CAN FD capability to a high-speed CAN transceiver class （对比 TJA1057GTKZ)
- Provides multiple network-state options （对比 TJA1442AT/0Z)
- Uses the established 8-pin SO family footprint （对比 TJA1057GTKZ)
设计说明
Place the TJA1441DT/0Z close to the CAN connector or bus-header entry point, and route CANH and CANL as a closely coupled differential pair. Keep the pair away from switching regulators, relays, motor traces and other high-current paths. Provide a low-impedance ground-plane connection and use the decoupling arrangement specified in the NXP TJA1441 datasheet.
Do not substitute a CAN FD-capable device without reviewing protocol behavior, mode-control logic and pin compatibility. NXP describes the TJA1441 as a replacement for TJA1051 and TJA1057-class transceivers, but CAN FD support changes system timing and software expectations. For an existing board, verify every package connection and confirm that the attached controller supports the selected communication mode.
Bus termination belongs at the physical ends of the CAN network rather than at every node. Keep the transceiver's bus-side connection compact, and avoid long stubs between the transceiver and connector. Use the manufacturer reference application and layout guidance when defining the CANH/CANL geometry, grounding strategy and supply-decoupling network.
