TJA1043TKY 概要

NXP Semiconductors TJA1043TKY is a high-speed CAN transceiver for automotive networking, providing one CANbus transceiver with differential transmit and receive capability for a protocol controller. The verified distributor data identifies a maximum data rate of 5 Mbps, a 5 V supply, normal, sleep, and standby operating modes, AEC-Q100 qualification, and a 14-pin HVSON package measuring 3 x 4.5 mm. It interfaces a Controller Area Network protocol controller with the physical two-wire CAN bus.

A Controller Area Network transceiver is a physical-layer interface within the CAN network hierarchy. A CAN protocol controller generates and interprets framed messages, while the transceiver converts those digital controller signals into differential bus levels and converts received bus levels back into controller-compatible signals. This division keeps protocol handling and physical-layer signaling separate, allowing a microcontroller-based CAN controller to communicate over a differential, fault-tolerant vehicle network.

The TJA1043TKY supports high-speed CAN communication up to 5 Mbps and includes standby and sleep modes for reduced power use when communication is not continuously required. Normal mode supports active bus communication, while the low-power modes help manage operating current in parked or partially active vehicle systems. The part is identified by distributor listings as automotive-grade and AEC-Q100 qualified. Its small HVSON package supports compact electronic control-unit layouts, although exposed-pad layout and thermal management must follow the NXP datasheet.

The transceiver provides the required interface between a CAN protocol controller and the physical two-wire CAN bus. Differential signaling improves common-mode rejection on vehicle networks, while the transceiver handles the electrical relationship between controller-side TXD and RXD signals and bus-side CANH and CANL conductors. Because these signals interact with wiring, termination, protection, and electromagnetic compatibility requirements, PCB layout and cable routing remain as important as controller firmware.

Typical uses include automotive body-control modules, powertrain controllers, gateway units, comfort systems, engine controllers, and industrial CAN equipment connected to vehicle-grade electronics. The verified data specifically associates the device with 5 Mbps CAN, 5 V operation, low-power sleep and standby states, and automotive qualification. It is suitable when an existing design uses the 14-HVSON footprint and its exact pin functions and exposed-pad requirements.

A critical design step is to reproduce the manufacturer-recommended package land pattern, pin assignments, CAN bus routing, termination, and decoupling exactly from the datasheet. Do not infer exposed-pad connections or bus-component values from the distributor summaries. Before release, validate timing, bus loading, fault behavior, sleep current, EMC performance, and wake behavior across temperature and supply tolerances using the complete manufacturer documentation.

This page combines verified distributor specifications, official NXP documentation, application guidance, and drop-in-replacement constraints. It also identifies where detailed pin-level, electrical-limit, lifecycle, price, and certification information requires direct verification from the manufacturer datasheet or current distributor quotation.

主な用途

TJA1043TKY の用途: 6 件s: Automotive Body Control Module, Automotive Gateway Controller, Powertrain Electronic Controller, Vehicle Comfort and Infotainment Network, Industrial CAN Equipment, CAN Test and Measurement.

🚗

Automotive Body Control Module

The TJA1043TKY fits a body-control CAN node because it connects a microcontroller or dedicated CAN controller to the physical two-wire network at rates up to 5 Mbps. Differential CANH and CANL signaling supports communication among doors, lighting, climate controls, and other distributed vehicle functions. The verified 5 V operation, sleep and standby states, AEC-Q100 identification, and compact 14-HVSON package are useful for space-constrained modules that must remain compatible with low-power vehicle networks. Layout must follow NXP's exact land pattern and route the differential pair as a controlled network.

🌐

Automotive Gateway Controller

The TJA1043TKY can provide the physical-layer interface for an in-vehicle gateway node when another microcontroller or CAN controller handles frame routing. A rate of up to 5 Mbps accommodates high-bandwidth communication, while differential receive and transmit support the bus-side CANH/CANL connection. Sleep and standby operation can support reduced-power states in parked or network-inactive conditions. Because the transceiver has one CAN channel, designs requiring multiple CAN domains should add additional transceivers and validate isolation, termination, routing, and fault behavior separately.

🚗

Powertrain Electronic Controller

The TJA1043TKY is a candidate for a CAN connection in an engine, transmission, or hybrid powertrain controller because the verified data identifies automotive qualification and operation up to 5 Mbps. It handles the physical CAN interface rather than control algorithms, diagnostics, or actuator drive. Designers should verify the exact temperature grade and electrical limits against the production ECU requirements, then implement the manufacturer's recommended protection, termination, decoupling, and exposed-pad layout. Diagnostic behavior and bus fault recovery must also be validated with the associated CAN controller.

📺

Vehicle Comfort and Infotainment Network

The TJA1043TKY can connect comfort-domain modules such as climate, seat, lighting, and infotainment controllers to a shared two-wire CAN network. Differential bus signaling helps reject common-mode noise present around vehicle wiring, while the verified 5 Mbps capability supports a broad range of control and status traffic. The standby and sleep modes are useful when an ECU should reduce activity without leaving the network immediately. Software should coordinate wake and sleep transitions so a partial-power node does not disturb communication among other modules.

🏭

Industrial CAN Equipment

The TJA1043TKY can be evaluated for industrial machinery, robotics, or test equipment that uses a compatible 5 V, high-speed CAN physical layer. Its single transceiver and maximum 5 Mbps rate suit distributed control and monitoring nodes with moderate bandwidth requirements. The automotive qualification may provide confidence for harsh installations, but industrial users must still confirm electrical limits, temperature range, EMC performance, and long-term availability. Sleep and standby states can reduce system consumption when motion stops or a machine enters a controlled idle state.

🖥️

CAN Test and Measurement

The TJA1043TKY can form the physical interface in a CAN analyzer, interface module, or automated test fixture. A maximum data rate of 5 Mbps supports monitoring and injection in systems that comply with the device's timing and bus requirements, while normal, sleep, and standby states provide useful control for bench equipment. The designer must provide compatible termination, test hooks, protection, and a controller capable of generating the required CAN frames. Measurement accuracy and fault coverage depend on instrumentation, calibration, isolation, and firmware rather than the transceiver alone.

What is the TJA1043TKY and what does it do?
The TJA1043TKY is a 5 Mbps, high-speed CAN transceiver that interfaces a CAN protocol controller with a physical two-wire CAN bus. According to the NXP TJA1043 datasheet, it provides differential transmit and receive capability in a 14-HVSON package. The CAN controller creates and interprets messages, while the transceiver connects its TXD and RXD interface to the bus-side CANH and CANL conductors.
What are the key specifications of TJA1043TKY that engineers should know?
The TJA1043TKY is a single 5 V high-speed CAN transceiver rated for data rates up to 5 Mbps. NXP and authorized distributor listings identify normal, sleep, and standby modes, differential bus communication, automotive application, AEC-Q100 qualification, and a 14-HVSON package measuring 3 x 4.5 mm. These facts define its core suitability, while detailed voltage tolerances, current limits, timing, and thermal limits must be checked in the manufacturer datasheet.
Where can I download the TJA1043TKY datasheet PDF?
The official TJA1043 datasheet is available from NXP at https://www.nxp.com/docs/en/data-sheet/TJA1043.pdf. It is the controlling source for the complete HVSON pinout, electrical limits, timing, power modes, application circuit, and recommended PCB layout. Search-result listings also expose datasheet mirrors, but engineers should prefer the NXP PDF because it is the authoritative manufacturer document.
Where can I find the TJA1043TKY pinout?
The TJA1043TKY pinout must be taken from the pin table in the official NXP TJA1043 datasheet, particularly the 14-HVSON package diagram and connection table. Distributor summaries confirm a 14-HVSON package but do not reproduce every terminal name. Treat the exposed thermal pad separately and verify whether it is tied to a specific supply or ground pin exactly as directed by NXP.
How many CAN transceivers are integrated into TJA1043TKY?
The TJA1043TKY contains one high-speed CAN transceiver, represented by DigiKey as a one-transceiver, one-channel device. It supports one physical two-wire CAN interface for a compatible protocol controller. It is not an eight-channel CAN controller and does not independently terminate or bias the bus; those network functions must be designed separately according to the application requirements.
What is the maximum CAN data rate supported by TJA1043TKY?
The TJA1043TKY supports CAN operation up to 5 Mbps, according to the verified Arrow listing and NXP product description. This is the maximum physical-layer data rate supported by the transceiver family. Practical communication timing also depends on oscillator accuracy, CAN-controller configuration, cable length, topology, termination, propagation delay, electromagnetic conditions, and the complete system design.
What supply voltage and operating modes does TJA1043TKY use?
The verified distributor data specifies a 5 V supply and normal, sleep, and standby operating modes. Normal mode performs active CAN communication, while sleep and standby support reduced-power system states. Exact voltage tolerances and mode-transition current values are not present in the supplied snippets, so they must be verified from the official NXP datasheet before setting power rails or designing a wake controller.
Is TJA1043TKY qualified for automotive applications?
The TJA1043TKY is identified as an AEC-Q100-qualified automotive 5 Mbps CAN transceiver by Arrow's verified product listing. That qualification makes it a candidate for demanding automotive electronic systems, but qualification alone does not establish suitability for a specific vehicle program. Designers must still verify temperature grade, quality flow, supplier sourcing, software requirements, EMC testing, and all production-program requirements.
Where can I buy TJA1043TKY online?
TJA1043TKY listings are available from Mouser, DigiKey, Arrow, and other authorized distributors in the verified web results. The reference pricing shown on this page is in USD as of 2026-10-22 and should be treated as a current-page reference rather than a guaranteed quotation. Confirm exact stock, authorized-channel status, lot traceability, packaging, and delivered price before placing a production order.
What is the price of TJA1043TKY?
The reference price for one TJA1043TKY is USD 2.87 as of 2026-10-22, with volume tiers shown for quantities of 10, 100, 500, and 1,000. The supplied search results confirm distributor availability and pricing pages but do not provide a consistent price table, so buyers should request a live quote. Tax, freight, date code, lot status, warranty, and quantity availability may change the final cost.
What is the lead time for TJA1043TKY?
A definitive TJA1043TKY lead time is [DATA_NEEDED: current manufacturer or distributor lead time]. DigiKey's listing says ships today, but that is a point-in-time distributor statement rather than a guaranteed production lead time. Contact the selected authorized distributor with your required quantity and date code to confirm allocation, factory schedule, and any automotive supply constraints before committing the design.
Is TJA1043TKY in stock?
TJA1043TKY appears available through multiple distributor listings in the verified results, but current inventory changes continuously. DigiKey states that the part ships today, while Mouser, Octopart, and Arrow expose stock or quotation tools for current checks. Treat availability as BackOrder in structured commerce data unless a distributor confirms stock for the exact package, quantity, and lot date.
TJA1043TKY vs TJA1042T - which CAN transceiver fits the design?
The TJA1043TKY supports 5 Mbps operation in normal, sleep, and standby modes, whereas the verified TJA1043 data does not establish the TJA1042T data rate, modes, package, or pin compatibility. Choose TJA1043TKY when its documented 5 Mbps rate and low-power modes satisfy the system requirements. Do not treat the TJA1042T as a drop-in replacement without a verified manufacturer package drawing and pin-by-pin cross-reference.
When should I choose TJA1043TKY instead of a basic CAN transceiver?
Choose the TJA1043TKY when the design specifically benefits from its verified 5 Mbps capability, normal/sleep/standby modes, automotive qualification, and 14-HVSON implementation. A basic transceiver may be preferable only when those features are unnecessary and a verified compatible device offers lower cost. Final selection depends on voltage range, bus timing, fault behavior, package, thermal requirements, and channel count.
Is TJA1043TKY suitable for an automotive gateway controller?
The TJA1043TKY is suitable as a candidate for an automotive gateway CAN interface because the verified data identifies a 5 Mbps rate, low-power sleep and standby modes, and AEC-Q100 qualification. It sits between the MCU or CAN controller and physical CANH/CANL wiring. Suitability remains dependent on exact electrical limits, operating temperature, wake requirements, EMC validation, and qualification details in the full NXP datasheet.
What can replace TJA1043TKY as a true drop-in part?
No verified same-package, pin-to-pin drop-in replacement was established from the supplied cross-reference results. The generic tools and product pages do not prove package identity, pin mapping, electrical equivalence, standby behavior, sleep behavior, or firmware compatibility. Treat any proposed substitute as unverified until its manufacturer documents a matching 14-HVSON footprint and complete terminal functions; otherwise, a PCB redesign may be required.
What is the best NXP equivalent for TJA1043TKY?
The best direct match is the base NXP family designation TJA1043, because the manufacturer identifies TJA1043 as the same high-speed transceiver family and distinguishes the ordering code TJA1043TK by packaging. However, TJA1043TK alone is not automatically a drop-in for TJA1043TKY unless its package suffix confirms the identical tape-and-reel 14-HVSON format and the approved manufacturer documentation confirms the same electrical and pin configuration.

エンジニアリング参考データ: TJA1043TKY — 比較、設計ガイダンス、コンプライアンス情報。

選定ガイド

Choose TJA1043TKY when the design needs a single 5 V CAN physical-layer interface capable of 5 Mbps communication, particularly in an automotive electronic module with sleep and standby power management. Its AEC-Q100 identification and compact 14-HVSON package support that use case, but designers must still verify temperature grade, lifecycle commitments, and vehicle-program requirements. TJA1043TK is the closest NXP family candidate, yet the exact suffix, pinout, and ordering equivalence require confirmation before treating it as a drop-in. If another manufacturer offers a lower-cost device, approve it only after checking package, terminal mapping, mode-control behavior, electrical limits, CAN timing, and low-power current. Do not select a different CAN package merely by matching protocol or nominal speed.

設計ノート

Use the official NXP HVSON land pattern and pin table exactly. Confirm whether the exposed pad connects to a specified power or ground terminal, follow the required via arrangement, and keep CANH/CANL routing away from switching nodes and high-current paths. The supplied distributor results confirm the 3 x 4.5 mm package but do not provide the terminal map, so no pin or pad connection should be inferred from the package name alone.

Route CANH and CANL as a closely coupled differential pair with continuous return-path reference, matched clearances where practical, and minimal stubs. Place termination, protection, and transceiver circuitry according to the manufacturer application guidance. Keep the bus away from antennas, clocks, and switching-power loops because common-mode noise and impedance discontinuities can cause communication errors even when the controller is operating within its nominal settings.

Design the 5 V rail with the decoupling and tolerances required by the full NXP datasheet, and verify low-power behavior for both normal and sleep transitions. Do not assume that standby and sleep state currents are interchangeable. Use firmware and external wake circuitry to ensure partial-power nodes do not hold the bus in an unintended dominant state or prevent other ECUs from communicating during low-power intervals.

Avoid choosing a substitute solely because both devices are CAN transceivers. Pin mapping, logic levels, mode controls, package exposed pad, bus timing, electrical limits, and sleep behavior must all match. The supplied cross-reference results did not verify five distinct same-package replacements, so TJA1043TK is the only family-related candidate and should not be treated as a final drop-in approval without manufacturer documentation and board-level validation.
