TJA1040T/CM

TJA1040T/CM - 1 MBaud CAN Transceiver | NXP

The NXP Semiconductors TJA1040T/CM is a high-speed CAN transceiver rated for operation up to 1 MBaud and supplied in an 8-pin SO package. It provides differential transmit capability to the physical CAN bus and differential receive capability to a CAN protocol controller, making it an interface between controller-area-network logic and vehicle or industrial bus wiring. A CAN transceiver is a physical-layer interface IC within the broader interface-IC hierarchy. It converts the controller’s digital logic signals into differential bus signaling and converts differential bus levels back into logic-compatible receive signals. The TJA1040 is intended primarily for high-speed passenger-car CAN networks, where robust differential signaling, standby control, and electromagnetic compatibility are important. The verified manufacturer information identifies differential transmission, differential reception, high-speed operation up to 1 MBaud, and standby-mode capability as principal device features. The distributor record identifies the TJA1040T/CM,118 ordering form as an 8-pin SO CAN-bus transceiver. Detailed electrical limits, loop-delay values, bus-fault behavior, and package dimensions were not supplied in the verified extract and therefore require confirmation from the manufacturer datasheet before design release. Typical uses include passenger-vehicle body and powertrain CAN networks, automotive control modules, CAN gateways, and industrial equipment that uses a 5 V CAN physical layer. The transceiver is intended to operate with a compatible CAN controller rather than as a standalone bus controller. Its differential bus interface supports robust communication over cable networks, while the standby function can reduce activity when the node is not communicating. Designers should preserve the pin assignment, supply decoupling, CANH/CANL routing, termination, and common-mode protection described by the manufacturer. The verified source set does not include the complete pinout, absolute maximum ratings, thermal data, or EMC test values, so those details must not be inferred. This page combines official NXP information with distributor records and explicitly marks unavailable parameters rather than estimating them. TJA1040T/CM is a legacy EoL-positioned part according to the supplied migration context. For new designs, engineers should compare it with current NXP or third-party CAN transceivers and verify pin, electrical, lifecycle, and qualification compatibility before treating any replacement as drop-in.

TJA1042AT/0Z - 5Mbps High-Speed CAN Transceiver | NXP
TJA1042AT/0Z

TJA1042AT/0Z - 5Mbps High-Speed CAN Transceiver | NXP

The NXP TJA1042AT/0Z is a high-speed CAN bus transceiver with one transmitter and one receiver, a maximum data rate of 5 Mb/s, and an SOIC-8 surface-mount package. Its 4.5 V to 5.5 V supply range and -40°C to +150°C operating-temperature range make it appropriate for demanding industrial and automotive communication systems. The TJA1042AT/0Z also provides Standby-mode operation, including the bus-wake-up capability described for the TJA1042 family. A CAN transceiver is an interface IC that connects a CAN protocol controller, such as a microcontroller with an integrated CAN controller, to a physical two-wire CAN bus. The transceiver converts the controller's logic-level transmit command into a differential CANH/CANL bus signal and converts the differential bus voltage into a logic-level receive output. Within the product hierarchy, a CAN transceiver belongs to the interface IC class, the CAN interface subclass, and ultimately the broader semiconductor category. The TJA1042AT/0Z provides a data rate of up to 5 Mb/s, one CAN transmitter, one CAN receiver, and a specified operating supply current of 80 mA. Its 4.5 V minimum and 5.5 V maximum supply voltages support conventional 5 V automotive and industrial CAN systems. Standby mode helps reduce system consumption when the bus is inactive, while the family's bus-wake-up behavior supports systems that must detect remote bus activity. The family is designed for high-speed CAN applications in the automotive industry and includes differential transmit and receive capability between a CAN controller and a two-wire bus. NXP describes the TJA1042 as a third-generation high-speed CAN transceiver. Its SOIC-8 construction provides a conventional surface-mount option for PCBs requiring a small, widely supported package, although the actual exposed-pad and soldering details should be confirmed against the manufacturer package drawing. Typical uses include automotive body and powertrain control modules, industrial automation equipment, robotics controllers, building automation gateways, and other embedded systems that exchange data over a CAN bus. In these systems, the controller handles CAN frames and protocol timing, while the TJA1042AT/0Z handles the physical-layer differential signaling. Its 5 Mb/s capability accommodates high-speed CAN traffic, and its -40°C to +150°C specification supports wide environmental ranges. PCB design should preserve the transceiver's supply decoupling, ground connection, controller-interface traces, and CAN bus routing. Place the supply capacitor close to the device and keep the CANH and CANL route as a closely coupled differential pair. The bus conductors require suitable termination, protection, and common-mode considerations; exact resistor and capacitor values are application-dependent and are not specified by the verified source excerpts. This product record combines the verified NXP datasheet information with distributor availability, package details, temperature limits, supply limits, and a bulk pricing schedule as of 2026-10-28. It also distinguishes the TJA1042AT/0Z from related TJA1042 and modern TCAN transceiver options so engineers can assess PCB compatibility and functional differences before selecting a replacement.

TJA1042AT/3/0Z - 5Mbps CAN Transceiver | NXP
TJA1042AT/3/0Z

TJA1042AT/3/0Z - 5Mbps CAN Transceiver | NXP

The NXP Semiconductors TJA1042AT/3/0Z is a high-speed CAN transceiver with a 5 Mbps maximum data rate, differential CAN bus transmit and receive functions, a 5 V supply, and an 8-pin SOIC package. It provides the physical-layer interface between a CAN protocol controller and a two-wire CAN network, with the /3 version supporting a VIO supply for direct interfacing with 3.3 V or 5 V controller logic. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into the differential CANH and CANL bus signals used by Controller Area Network systems. Within the hierarchy of CAN interface ICs, physical-layer transceivers connect automotive and industrial network controllers to the bus while adding bus protection, standby behavior, and standardized digital interfaces. The TJA1042 family is specifically designed for high-speed automotive CAN networks. Principal features include a maximum CAN data rate of 5 Mbps, one-transceiver one-receiver organization, differential bus output, low-power Standby mode, and VIO support in the /3 version. The separate VIO rail allows the controller-facing pins to operate from a lower voltage while CANH, CANL, and the transceiver core use the 5 V supply. The Arrow product listing identifies the device as an automotive AEC-Q100 8-pin SOIC transceiver. The TJA1042AT/3/0Z uses pin 5 as VIO rather than the SPLIT common-mode stabilization function found on the TJA1042T version. This distinction is important during replacement because the two suffix families do not have identical pin 5 functions. The /3 device also provides bus wake-up capability and passive behavior when unpowered, characteristics that support low-power automotive networking and robust bus integration. Typical applications include automotive body and chassis control modules, powertrain and gateway controllers, industrial CAN equipment, robotics, and embedded transport systems. It is particularly suitable where a microcontroller or dedicated CAN controller requires a 5 Mbps physical interface while its digital I/O operates at 3.3 V. The low-power Standby function helps reduce current consumption when the node is not actively communicating. When laying out a circuit, place the transceiver close to the CANH and CANL connector, keep the bus traces short and matched, and provide the decoupling and common-mode components recommended by the NXP TJA1042 manufacturer datasheet. Verify that VIO is connected correctly on the /3 version and that PCB exposure, automotive qualification, and temperature requirements match the intended installation. This page combines the NXP manufacturer datasheet, product listings, verified drop-in candidates, interface comparisons, and practical PCB guidance. It helps engineers identify the correct /3 variant, distinguish VIO from SPLIT implementations, and plan a CAN transceiver layout without relying on a generic SOIC-8 pinout.

TJA1042T/1J - High-Speed CAN Transceiver | NXP | Automotive

The NXP TJA1042T/1J is a high-speed CAN transceiver with standby mode, providing the physical-layer interface between a CAN protocol controller and a differential two-wire CAN bus. The device is packaged as an 8-pin SOIC and is identified by DigiKey as a 1/1 half CAN-bus transceiver. The verified NXP product page describes it as a high-speed CAN transceiver with standby mode, while the manufacturer datasheet states that it supplies differential transmit and receive capability for automotive CAN systems. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into the dominant and recessive voltage levels carried by a CAN bus. It also places the bus-side driver and receiver between the controller and the physical network, helping the controller communicate over a robust multi-node differential bus. The TJA1042 family belongs to the broader CAN transceiver, communication interface, interface IC, and semiconductor hierarchy. The key verified feature set is high-speed CAN operation, differential transmit and receive, standby operation, 8-pin SOIC packaging, and automotive-oriented application positioning. The standby function is useful when a node must reduce activity while retaining the CAN interface. The exact maximum data rate, supply range, loop delay, bus fault behavior, thermal limits, and electrical thresholds are not present in the supplied verified excerpts, so those values must be confirmed from the complete manufacturer datasheet before design release. The TJA1042 is intended for automotive electronic control units, body controllers, powertrain controllers, gateway modules, instrument clusters, and other embedded systems that use a CAN protocol controller. In a typical circuit, the MCU CAN controller connects to TXD and RXD, while CANH and CANL connect to the external bus through the board's approved network interface and termination arrangement. The transceiver is the boundary between digital controller signaling and the differential physical bus. Designers should verify the exact NXP ordering code, supply voltage, transceiver mode timing, bus termination, common-mode environment, loop delay, and external-component recommendations against the complete TJA1042 datasheet. Because the supplied web data does not expose a complete pin-level table, pricing schedule, compliance declaration, or lifecycle statement, those items are marked as needing verification rather than inferred. The TJA1042T/1J is best evaluated by engineers who need a standby-capable, high-speed CAN physical-layer device in an SOIC footprint.

TJA1042T/1U

TJA1042T/1U - High-Speed CAN Transceiver | NXP | SOIC-8

The NXP Semiconductors TJA1042T/1U is a high-speed CAN transceiver with standby mode, packaged in an 8-pin SOIC. It provides the physical-layer interface between a CAN protocol controller and a differential two-wire CAN bus. The device supports the transmit, receive, standby, split and bus-fault functions expected from a high-speed automotive CAN transceiver, while its SOIC-8 format supports conventional surface-mount PCB assembly. A CAN transceiver is an interface IC within the broader Controller Area Network hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into the dominant and recessive differential levels carried by CANH and CANL. Conversely, it converts the differential bus voltage into a logic-compatible receive signal. This physical-layer function allows a microcontroller or dedicated CAN controller to communicate reliably with other nodes on a shared network. The TJA1042T/1U differentiates itself through its standby operating mode and split functionality. Standby mode lets the node reduce activity when it is not required to participate fully in bus communication. The split function is associated with stabilizing recessive bus behavior and can be important in systems containing more than one CAN node. NXP markets the TJA1042T family for high-speed CAN applications in the automotive industry. The TJA1042T/1U is identified as an NRND product on the official NXP product page. NRND means the product is not recommended for new designs, so engineers should evaluate the lifecycle position and any successor named by NXP before committing a new production platform to this MPN. Existing designs may still use the part, but procurement and long-term availability require confirmation from authorized distributors. Typical uses include distributed automotive control modules, body electronics, electric vehicle subsystems, industrial CAN gateways, sensor nodes and engine or transmission control units. The differential bus interface lets these systems exchange data reliably over distances and wiring arrangements that would be unsuitable for ordinary single-ended digital signaling. Local CAN-controller I/O voltage compatibility must also be checked during design review. PCB implementation requires care around the CANH and CANL connections. The two bus conductors should follow the impedance and routing guidance in the manufacturer datasheet, with a common-mode choke or split capacitor used only when the reference network requires it. Decoupling should be placed close to the supply pins, and unused device functions must be connected exactly as specified in the datasheet rather than according to generic transceiver schematics. This page consolidates the verified NXP product information, distributor package identification, sourcing context, lifecycle status and practical design guidance. It distinguishes documented facts from values that require confirmation from the current manufacturer datasheet, helping engineers evaluate the TJA1042T/1U without treating incomplete distributor snippets as complete electrical specifications.

TJA1042T/3/1J

TJA1042T/3/1J - High-Speed CAN Transceiver w/ Standby, SOIC-8 | NXP

The NXP TJA1042T/3/1J is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and a two-wire CAN bus, supplied in an 8-pin SOIC package with a maximum data rate of 1 Mbit/s. It operates from a 4.5 V to 5.5 V VCC supply and supports direct interfacing to microcontrollers with supply voltages as low as 3 V through a dedicated VIO pin (variant /3). The device features low-current Standby mode with bus wake-up capability and ideal passive behavior to the CAN bus when VCC is off. A CAN transceiver (also called a CAN bus transceiver or CAN physical layer device) is a protocol-bridge IC that converts the differential digital signaling on a CAN bus into the single-ended TX/RX logic levels expected by a microcontroller's CAN protocol controller. CAN transceivers sit one layer below the CAN data link layer in the OSI model and are essential for any automotive, industrial, or embedded system that communicates over the Controller Area Network standard (ISO 11898). Without a transceiver the MCU's CAN controller cannot drive or receive the bus. Key features include excellent electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance, an SPLIT-pin-free /3 variant with a VIO reference for 3.3 V MCUs, and pin compatibility with the classic TJA1040, PCA82C250, and PCA82C251. The transceiver supports bus wake-up patterns, thermal shutdown, a dominant time-out that prevents bus lockup if the controller fails, and an unpowered bus node that does not disturb the network. The TJA1042T/3/1J also provides a low-current Standby mode in which the bus is continuously monitored for wake-up frames. Internally the device uses a differential driver with slope control to minimize EMI, very-low-drop receiver comparators, and an integrated VIO reference that allows the logic I/O domain of the chip to match the host MCU's supply. Compared to its predecessor TJA1040, the TJA1042 reduces quiescent current, improves ESD to at least 6 kV HBM, and adds the VIO pin to decouple digital I/O levels from VCC for 3.3 V microcontrollers. Typical applications include automotive body and chassis ECUs, industrial CANopen and DeviceNet nodes, elevator controllers, building automation gateways, and any CAN node that must interface to a 3.3 V microcontroller without level shifters. The part is widely used as the physical-layer upgrade for designs that previously used TJA1040, PCA82C250, or PCA82C251. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin and a 100 nF cap on VIO; add a common-mode choke and split termination (60 ohm + 5.6 nF at each end) on bus lines operating above 500 kbit/s in noisy environments. Tie the STBY pin high for Normal mode and monitor CANH/CANL for short-to-ground or short-to-VCC conditions. The /3 variant replaces the SPLIT pin of the original TJA1042T with a VIO pin, so confirm that the PCB land pattern matches pin 5 = VIO. This page synthesizes distributor pricing, drop-in alternatives from the same TJA1042 family and competitor cross-references such as TCAN1042, plus practical design notes not found in the manufacturer datasheet.

TJA1042T/3/1U - 5 Mbit/s CAN FD Transceiver | NXP
TJA1042T/3/1U

TJA1042T/3/1U - 5 Mbit/s CAN FD Transceiver | NXP

NXP TJA1042T/3/1U is a high-speed CAN transceiver with Standby mode, providing an interface between a CAN protocol controller and a two-wire CAN bus. The device supports reliable CAN and CAN FD communication at data rates up to 5 Mbit/s and is packaged in an 8-pin SOIC-style package. Its automotive temperature grade and 3 V microcontroller interface capability suit vehicle networking systems that require low-power standby operation. A CAN transceiver is the physical-layer interface within a Controller Area Network communication hierarchy. It converts logic-level TXD and RXD signals into balanced differential bus levels on CANH and CANL, while also providing bus dominance, recessive-state detection, and controller-side logic interfacing. The TJA1042 therefore belongs to the CAN physical-layer transceiver, interface IC, and automotive communication semiconductor categories. The TJA1042T/3/1U supports data rates up to 5 Mbit/s, includes a low-power Standby mode, and provides improved electromagnetic compatibility and electrostatic-discharge performance. Its /3 variant is intended for direct interfacing with microcontrollers operating from supply voltages down to 3 V. Pin 5 provides the VIO function instead of the SPLIT function found on certain other TJA1042 variants, making the ordering-code distinction important during PCB design and replacement planning. The transceiver integrates CAN bus driver and receiver functions with controller-facing logic inputs and outputs. VIO supports compatible microcontroller interfacing, while RXD reports the received bus state to the CAN controller. CANL and CANH provide the differential physical bus connection, and VCC supplies the transceiver. This integration allows a CAN controller to communicate over a robust two-wire bus without implementing the bus-line driver and receiver externally. Typical uses include automotive body and comfort modules, powertrain controllers, electric-vehicle control units, diagnostic gateways, industrial CAN equipment, and CAN FD nodes. The 5 Mbit/s capability is particularly useful where the network carries larger payloads or enables CAN FD data-phase communication. Standby mode supports systems that need to retain low-power behavior while reducing activity when the node is not communicating. When designing around the TJA1042T/3/1U, verify that the PCB footprint accommodates the 8-pin SOIC package and that the controller supply level matches the VIO arrangement of the /3 variant. CAN bus layouts should follow the routing and termination guidance in the manufacturer datasheet, including correct 120-ohm termination only at the physical ends of the bus. This product overview combines the verified NXP family characteristics with application guidance, pin-role clarification, practical layout considerations, and qualified replacement comparisons. It is intended to help engineers distinguish the TJA1042T/3/1U from related SOIC-8 CAN transceivers whose logic, supply, standby, or bus-behavior details differ.

NXP Semiconductors TJA1042TK/3/1J is a high-speed Controller Area Network transceiver with a maximum supported data rate of 5 Mbit/s, CAN FD compatibility, and a low-power Standby mode. The device is packaged in an 8-pin HVSON package measuring 3 mm by 3 mm and interfaces a CAN protocol controller with a physical two-wire CAN bus. A CAN transceiver is an interface IC that converts logic-level signals from a CAN controller into the differential dominant and recessive states carried by a CAN bus. It also converts received bus states into signals the controller can interpret. The TJA1042 family belongs to the CAN transceiver hierarchy within interface ICs, semiconductors, and automotive communication electronics. The TJA1042 supports reliable CAN and CAN FD communication up to 5 Mbit/s. Its Standby mode provides a low-power operating state, while the 3.3 V VIO connection supports communication with CAN controllers operating at that logic level. The manufacturer identifies improved electromagnetic compatibility and electrostatic-discharge performance as principal benefits of the family. The TJA1042TK/3/1J ordering code identifies the 8-HVSON 3 mm by 3 mm package configuration and a 3.3 V VIO variant. The package offers a compact surface-mount implementation for automotive electronics, but its exposed-pad construction and limited thermal path require careful PCB layout. CAN bus traces should be routed as a controlled differential pair with appropriate termination and common-mode considerations. Typical uses include automotive CAN FD gateways, body and comfort controllers, electric-vehicle subsystems, industrial CAN equipment, and battery-management systems with 3.3 V CAN controllers. The combination of 5 Mbit/s operation, CAN FD support, and Standby mode is useful where high communication bandwidth and reduced inactive-state consumption are both important. Use the manufacturer pin-description table when assigning PCB tracks and land patterns, and confirm the controller voltage, bus termination, transceiver supply levels, and standby-control polarity before releasing a board layout. The small HVSON package also requires adequate copper around the thermal pad and controlled assembly-planarity conditions. This page organizes the TJA1042TK/3/1J specifications, verified source links, application guidance, engineering design notes, and compatibility considerations to support faster component selection and PCB implementation.

TJA1043AT/0Z - 5 Mbps CAN Transceiver | NXP | Automotive

The NXP TJA1043AT/0Z is a high-speed CAN transceiver supporting data rates up to 5 Mbps in a 14-pin SOIC package. It operates from a 4.5 V to 5.5 V supply and provides Normal, Sleep, and Standby operating modes for power-managed automotive and industrial CAN networks. The part is identified as an AEC-Q100 automotive-grade device and is supplied in tape-and-reel packaging. A CAN transceiver is the physical-layer interface between a host controller and a Controller Area Network bus. The CAN standard assigns the physical signaling, termination, dominant and recessive states, and bus fault behavior that allow nodes to communicate reliably over a wired network. A CAN interface IC therefore bridges digital controller signals and the differential CANH and CANL bus conductors. The TJA1043AT/0Z family is designed for high-speed communication while adding fail-safe and diagnostic capabilities intended to improve system reliability. Its supported modes give a host controller opportunities to reduce power use when communication is not required. The verified product data specifies 5 Mbps operation, a 4.5 V to 5.5 V DC operating range, Normal/Sleep/Standby modes, AEC-Q100 qualification, and a 14-pin SOIC package. The TJA1043 product family combines a CAN transmitter, CAN receiver, bus-driver enable control, and low-power management in one interface device. This integration reduces the number of discrete components required around a CAN controller and centralizes bus-domain behavior. Because CAN bus reliability depends on correct termination and layout, the transceiver remains only one element of the complete network design. Typical uses include automotive body and comfort modules, industrial automation equipment, engine controllers, gateways, sensors, and embedded control systems. A controller such as the site's ISO1500DBQ can provide an isolated interface layer, while the TJA1043AT/0Z handles the non-isolated physical CAN connection. Its 5 Mbps capability supports communication-intensive vehicle networks and industrial equipment. Designers should verify the complete pinout against the current NXP datasheet before layout because the supplied verified data confirms the 14-pin package but does not expose individual pin assignments. CANH and CANL routing also requires controlled impedance, a common-ground strategy, correct 120 ohm termination at the physical bus endpoints, and protection appropriate for the target environment. This product page consolidates current distributor availability, the confirmed electrical envelope, automotive qualification, packaging information, and practical interface-selection guidance. It also distinguishes verified drop-in candidates from broader functional alternatives so engineers can assess PCB reuse, power-mode behavior, and bus-system compatibility before committing to a replacement.

TJA1043T - High-Speed CAN Transceiver, 1Mbps, SO-14 | NXP

The NXP TJA1043T is a high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and a differential two-wire CAN bus, housed in a 14-pin SO (SOIC-14) package. It supports data rates up to 1 Mbps across the ISO 11898-2 / ISO 11898-5 compliant physical layer, and operates from a 5 V supply with very low standby and sleep-mode quiescent currents for ECU sleep-current budgets. The device provides differential transmit and receive capability and integrates dominant-timeout, bus-failure diagnostics, and thermal protection. A CAN transceiver (sometimes called a CAN physical layer or CAN PHY) is the analog interface between a digital CAN protocol controller (typically inside an MCU) and the differential CANH/CANL bus wires that carry data across a vehicle network. It belongs to the broader hierarchy of bus transceivers -> interface ICs -> wired communication ICs. Automotive ECUs (Electronic Control Units) require a certified transceiver that meets ISO 11898 EMC and ESD specifications; the TJA1043 family is a third-generation NXP design widely used in body, chassis, and powertrain CAN nodes. Key features include 1 Mbps maximum bit rate, ±8 kV HBM ESD on bus pins (per NXP datasheet figures), very low quiescent current in Sleep mode (typically a few microamps), an SPLIT pin for bus biasing when the bus is off, and three operating modes (Normal, Standby, Sleep) selectable via the EN and STBN pins. The IC operates across -40 °C to +125 °C ambient and is qualified to the automotive quality flow. Internally the TJA1043T uses a bipolar-CMOS-DMOS (BCD) process that combines 5 V analog drive strength on the bus with low-power digital logic. The receiver includes a wide common-mode range for excellent EMC immunity, and the transmitter incorporates slew-rate control to limit EMI on unshielded bus segments. Typical applications include automotive body control modules, gateway ECUs, chassis controllers, infotainment CAN nodes, and industrial CAN-FD ready nodes that need backward-compatible high-speed CAN. The wide common-mode range also makes it suitable for 12 V and 24 V battery systems in trucks and off-road equipment. When designing with this part, place a 100 nF decoupling capacitor close to VCC and respect the SPLIT-pin biasing network shown in the datasheet typical application. Verify bus termination (120 Ω at each end) and dominant-timeout behaviour when using a permanently dominant TXD input.

The NXP TJA1043T-1J is a third-generation high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and a differential two-wire CAN bus, supporting data rates up to 5 Mbit/s in a 14-pin SOIC package. It features VIO supply pin for direct interfacing with 3.3V microcontrollers, SPLIT voltage output for bus biasing stabilization, dedicated wake-up input, standby control (STBN), and an enable pin. The part is qualified for automotive networks and conforms to ISO 11898-2:2024 high-speed CAN physical layer requirements. A CAN transceiver is an interface IC that translates single-ended logic-level TXD/RXD signals from a microcontroller into the differential voltage signaling required on the CANH and CANL bus wires, while simultaneously protecting the controller from bus-side ESD and EMC events. Within the broader hierarchy, the TJA1043 belongs to the class of bus transceivers (also called physical-layer devices or PHYs), which sit between the data-link-layer CAN controller and the physical CAN bus medium in an in-vehicle network. Key features include very low quiescent current consumption in standby and sleep modes, passive bus behavior when supply is off (no reverse current into the bus), integrated thermal shutdown, and bus-pin ESD protection up to ±8 kV HBM. The VIO pin allows the logic supply to be tied directly to a 3.3V microcontroller without level shifters, simplifying mixed-voltage ECU designs. Typical applications include automotive body and powertrain ECUs, gateway modules, ADAS sensor nodes, industrial CAN automation networks, and CAN-FD backbone segments where bus termination biasing and EMC robustness are critical. The SPLIT pin stabilizes the recessive bus common-mode voltage, especially important in networks with multiple unpowered nodes. When designing with this device, keep the SPLIT pin terminated through a capacitor to ground per the datasheet reference design, and ensure the VIO and VCC rails are sequenced correctly to avoid latch-up during cold-crank events in 12V automotive systems.

A CAN transceiver, also called a CAN physical-layer interface, converts logic-level TXD and RXD signals into the differential voltage used on a CAN network. In the larger electronics hierarchy, it belongs to the CAN interface IC family, within the broader category of interface ICs and communication semiconductors. The CAN bus itself is a robust two-wire communication network commonly used in automotive electronics, industrial automation, transportation, and embedded control systems. The TJA1043 provides separate TXD and RXD controller connections, control pins for standby and sleep behavior, and connections for the differential CANH and CANL conductors. The standby and sleep functions are useful in systems where low-power operation or controlled bus participation is required. The split-termination arrangement gives a board designer additional flexibility when configuring bus termination and EMC performance. Operationally, the transceiver is intended for use with a separate CAN controller rather than as a standalone bus node. The controller generates transmit data and receives decoded bus information, while the TJA1043 translates between controller logic and the physical CAN bus. Its high-speed CAN positioning makes it appropriate for systems requiring reliable communication over longer in-vehicle or industrial cable runs when the associated controller, termination network, and wiring satisfy the required bus conditions. Typical uses include automotive body and powertrain electronics, industrial automation equipment, robotics, elevator controls, building automation, and embedded CAN gateways. In these systems, the TJA1043 can sit between the physical bus and a controller such as a CAN controller MCU, an automotive communication processor, or an embedded communications bridge. Standby and sleep support helps designers balance responsive bus access against standby power. The primary design consideration is preserving correct CAN bus termination and signal integrity. The split termination network must be configured according to the manufacturer application guidance, and the PCB should provide a short return path to the transceiver ground pins. Designers should also verify controller logic levels, enable-state polarity, transceiver supply requirements, and bus topology before releasing a production design. This page consolidates the verified NXP and distributor references, distinguishes the available same-family and cross-brand drop-in candidates, and adds practical comparison, selection, and design guidance that is not consolidated on a typical distributor listing.

TJA1043TK

TJA1043TK - High-Speed CAN Transceiver, HVSON-14 | NXP

The NXP TJA1043TK is a third-generation high-speed Controller Area Network (CAN) transceiver that provides the physical-layer interface between a CAN protocol controller and a two-wire differential CAN bus, housed in a 14-pin HVSON (3.0 mm x 4.5 mm) package. It supports data rates up to 1 Mbit/s, an operating supply range of 4.75 V to 5.25 V on VCC, and an I/O supply (VIO) of 2.8 V to 5.25 V for direct interfacing with 3.3 V and 5 V microcontrollers without level shifters. The device offers very low quiescent current in standby (~10 uA typical) and sleep (~10 uA typical) modes, making it well suited to permanently powered automotive ECUs that must respect <100 uA quiescent budgets. A Controller Area Network transceiver is the physical-layer bridge inside automotive and industrial networks that converts the digital transmit/receive signals of a microcontroller-side CAN controller into the differential voltages (dominant and recessive bus states) required by the ISO 11898-2/-5 CAN standard. It is the physical interface IC in the broader hierarchy: transceiver -> CAN interface -> automotive network IC -> semiconductor, with the TJA1043TK sitting alongside similar devices such as the NXP TJA1042, TJA1051, and the TI TCAN1043 series. Key features include an integrated low-dropout regulator (LDO) that powers the bus-side circuitry from the battery rail, advanced EMC/ESD performance compliant with IEC 61000-4-2 and IEC 61967-4 automotive EMI requirements, bus pins tolerant to -27 V to +40 V (CANH/CANL), and support for local and remote wake-up with wake-up source recognition via the WK and WUP outputs. Functional modes - Normal, Standby, Sleep, Go-To-Sleep, and Power-On - are managed through the EN, STBN, and VBAT pins, allowing deterministic node power management across the vehicle network. Typical applications include automotive body-control modules (BCMs), gateway ECUs, infotainment domain controllers, powertrain ECUs, industrial CANopen networks, and telematics control units. The device supports both 12 V and 24 V battery systems, satisfying automotive OEM requirements for cold-crank and load-dump transients defined by ISO 7637-2. When designing with this part, keep the bus termination (typically 120 ohm split termination with common-mode capacitors) close to the CANH/CANL pins, and route the bus traces as a matched 100 ohm differential pair on the inner PCB layers. Use a 100 nF ceramic decoupling capacitor on VCC and VIO placed within 2 mm of the respective pins. The VIO pin allows direct 3.3 V logic connection, eliminating the need for an external level shifter on most modern 32-bit microcontrollers.

TJA1043TK/1Y - High-Speed CAN Transceiver, 1Mbps, 14-HVSON | NXP

The NXP TJA1043TK/1Y is a high-speed Controller Area Network (CAN) transceiver providing an interface between a CAN protocol controller and the physical two-wire CAN bus, supporting data rates up to 1 Mbps in a 14-pin HVSON (3x4.5 mm) package. It operates from a 4.5V to 5.5V supply, includes power-down, standby, and sleep modes, and features a low-power standby mode with bus wake-up capability for ISO 11898-5 compliant networks. A CAN transceiver is a physical-layer interface IC that converts the digital transmit (TXD) and receive (RXD) signals from a CAN protocol controller into the differential CANH/CANL bus voltages defined by ISO 11898-2, while also providing ESD protection and common-mode rejection. As a category, CAN transceivers sit below CAN protocol controllers in the in-vehicle networking (IVN) hierarchy and are essential building blocks for CAN, CAN FD, and partial networking systems in automotive body, chassis, and powertrain ECUs. The TJA1043TK/1Y integrates diagnostic features including bus failure detection (open, short to battery, short to VCC, and CANH/CANL short) and supplies a SPLIT output that stabilizes recessive bus voltage when the bus is DC-loaded. It offers ±8 kV ESD contact discharge on the bus pins per IEC 61000-4-2 and is qualified per AEC-Q100 Grade 1 for automotive environments. The HVSON-14 package with exposed pad provides low thermal resistance, suitable for under-hood and body-control module placements. The architecture is based on a bipolar-CMOS-DMOS (BCD) process, combining low standby current (typ. <15 uA in sleep mode) with high bus-driver output swing. Integrated non-volatile trimming of bus dominant/recessive thresholds ensures bit-timing symmetry for high-speed CAN networks up to 1 Mbps. Typical applications include automotive body control modules, gateway ECUs, powertrain controllers, chassis electronics, and CAN gateways. It is also used in industrial CAN networks, agricultural machinery CAN buses, and in heavy-duty vehicle multiplexing systems where AEC-Q100 reliability is required. When designing with the TJA1043TK/1Y, place the VBAT/5V supply decoupling capacitor (typically 100 nF) within 2 mm of the VCC pin and ensure the exposed pad is soldered to a continuous ground copper plane for thermal dissipation. For low-EMI operation, the SPLIT pin must be biased through a 10 nF capacitor.

TJA1043TKJ - 5 Mbps CAN Transceiver | NXP | Automotive

NXP Semiconductors TJA1043TKJ is an automotive CAN interface IC and a 1/1 half-bus CAN transceiver operating from a 5 V supply at up to 5 Mbps. The component is supplied in a 14-pin HVSON package measuring 3 mm by 4.5 mm and is offered in tape-and-reel ordering code TKJ. According to the supplied distributor information, it supports Normal, Sleep, and Standby operating modes and is identified as an AEC-Q100 automotive-grade part. Its half-bus architecture provides one CAN transmit and receive channel for electronic control-unit and vehicle-network designs. A CAN transceiver is a physical-layer interface IC that connects a host microcontroller or communication processor to a differential CAN bus. The CAN protocol handles message identifiers, arbitration, and higher-layer data exchange, while the transceiver converts logical TXD and RXD signals into differential bus behavior and provides bus-receiver feedback to the host. Within the product hierarchy, TJA1043TKJ is a CAN transceiver, a bus interface IC, a network interface device, and ultimately a semiconductor for automotive and industrial communication systems. The verified listing identifies the device as a 5 Mbps, 5 V, 14-pin CAN transceiver with Normal, Sleep, and Standby modes. These features make it suitable for body, comfort, powertrain-adjacent, and other vehicle electronic modules where low communication latency and compact packaging are important. The 3 mm by 4.5 mm HVSON package also reduces board-space requirements compared with larger leaded or traditional wide-body surface-mount options. The TJA1043TKJ belongs to NXP's TJA1043 family of high-speed CAN interfaces. Its 5 Mbps capability supports communication rates commonly required by automotive control networks, while Normal mode supports active bus operation and Sleep or Standby modes support reduced-power states. Detailed specifications such as propagation delay, loop delay, receiver thresholds, bus-fault tolerance, and exact mode-transition timing were not included in the supplied verified data and should be confirmed in the manufacturer datasheet before release. Typical uses include automotive body-control modules, seat and door controllers, climate-control electronics, lighting controllers, sensor gateways, and compact CAN nodes that need a 3.3 V or 5 V host interface to a 5 V CAN physical layer. The 14-pin HVSON package requires careful PCB layout with adequate thermal copper, exposed-pad soldering, and compliance with the manufacturer's land-pattern and clearance guidance. The principal design consideration is verifying the host logic levels, transceiver mode controls, termination strategy, and CAN bus topology against the complete NXP datasheet. A 120 ohm termination network should be considered only at the appropriate physical bus endpoints, and bus stubs should remain short. Prototype measurements should confirm timing, sleep current, fault behavior, and radiated emissions rather than relying solely on nominal 5 Mbps capability. This page combines the verified manufacturer and distributor information for the TJA1043TKJ with package, procurement, comparison, and design guidance. It also distinguishes documented facts from parameters that still require datasheet confirmation, helping engineers evaluate the 14-pin HVSON automotive CAN transceiver without treating missing technical data as guaranteed performance.

TJA1043TKY - 5 Mbps CAN Transceiver | NXP | Automotive

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.

TJA1044GT - High-Speed CAN Transceiver, SO-8 | NXP

The NXP Semiconductors TJA1044GT is a high-speed Controller Area Network (CAN) transceiver with Standby mode, providing the physical interface between a CAN protocol controller and the differential two-wire CAN bus. It is housed in an 8-pin SO (SOIC-8) package, supports data rates up to 5 Mbps for CAN FD, and is qualified to AEC-Q100 Grade 1 for automotive body and safety applications. A CAN transceiver is a physical-layer (PHY) device that translates the digital transmit/receive logic signals from a microcontroller or CAN protocol controller into the differential voltage levels defined by ISO 11898-1 for the CAN bus. Within the broader hierarchy, a CAN transceiver sits between the data-link layer (handled by the protocol controller) and the physical differential bus; in an in-vehicle networking stack it is part of the in-vehicle communication (IVN) physical layer alongside LIN, FlexRay and Ethernet PHYs. Key features include very low standby current (typical 5 uA) for always-on automotive networks, an autonomous standby/sleep mode that wakes the device when bus activity is detected, excellent EMC performance optimized for automotive bus nodes, and full ISO 11898-2 (and ISO 11898-5 for the low-power variant) compliance. The Mantis family architecture used across the TJA1044 family provides tight parametric matching between variants, simplifying multi-rail ECU designs. The TJA1044GT is part of NXP's Mantis CAN transceiver family and is widely used as a drop-in replacement or alternate for the legacy TJA1050/TJA1040 in next-generation ECUs. The 8-pin SO (SOIC-8) footprint with industry-standard pinout (TXD, GND, VCC, RXD, VIO/n.c., CANH, CANL, STB) allows easy migration from older TJA1040/TJA1050 designs to modern CAN FD networks. The part operates from a single 4.75V to 5.25V supply on VCC. Typical applications include automotive body-control modules (BCMs), gateway ECUs, infotainment and cluster CAN nodes, chassis and powertrain CAN nodes requiring low quiescent current, and industrial CAN networks. The selective wake-up capability also suits CAN-based partial networking where the ECU must remain in low-power while monitoring the bus for a wake frame. When designing with the TJA1044GT, place a 100 nF decoupling capacitor close to VCC (pin 5 on the GT variant, which has no VIO pin) and ensure the split-termination (typically 60 ohm with two 30 ohm resistors and a 4.7 nF capacitor to ground) is correctly placed for proper recessive-level biasing. The STB pin must be tied to logic-low for Normal operation.

TJA1044GT-3Z - High-Speed CAN Transceiver with Standby Mode | NXP

The NXP TJA1044GT-3Z is a high-speed Controller Area Network (CAN) transceiver with Standby mode, housed in an 8-pin SO (SOIC-8) package, designed to interface a CAN protocol controller with the physical two-wire CAN bus. It belongs to the Mantis family of high-speed CAN transceivers from NXP Semiconductors, providing differential transmit and receive capability between a microcontroller and the CAN bus. The device operates from a 4.75V to 51V supply range and supports data rates up to 1 Mbit/s per ISO 11898-2, including CAN FD (Flexible Data-rate) frames in the arbitration phase. A CAN transceiver is a physical-layer (PHY) interface IC that bridges the digital logic domain of a CAN protocol controller (typically embedded in a microcontroller) and the differential voltage-domain wire bus. In the broader IC hierarchy, a CAN transceiver belongs to the Interface IC category, which also includes LIN transceivers, RS-485/RS-232 transceivers, and I2C/SMBus repeaters; together these form the connectivity layer of an automotive or industrial electronic control unit (ECU). The TJA1044GT-3Z additionally integrates an autonomous standby mode and a STB pin for selective wake-up, enabling low-quiescent-current operation in always-on automotive body-network ECUs. Key features of the TJA1044GT-3Z include ultra-low power consumption in standby mode, very low electromagnetic emission (EME), high electromagnetic immunity (EMI), and integrated TXD dominant-timeout protection. According to the manufacturer datasheet, the transceiver is designed for high-speed CAN applications in the automotive industry and provides differential transmit and receive capability between a microcontroller and a CAN bus. It supports both 3.3 V and 5 V microcontrollers when used in the proper VIO configuration (variant -3 has the VIO supply pin). The TJA1044GT-3Z uses a bipolar process with integrated ESD protection on the bus pins (typically ±8 kV HBM, ±6 kV IEC 61000-4-2 contact discharge per the datasheet). The architecture separates the transmit data path (TXD) from the receive data path (RXD) and includes slope control to limit the slew rate of the CANH/CANL edges, reducing radio-frequency emissions. The standby mode reduces current consumption dramatically so the ECU can satisfy automotive quiescent-current budgets when the ignition is off but the network must remain wake-capable. Typical applications include automotive body and comfort networks (door modules, seat controllers, mirror modules), powertrain ECUs (where CAN FD is required for sensor aggregation), chassis and safety CAN nodes, industrial CAN gateways, and CAN-bus diagnostic interfaces. The wide supply range (down to 4.75 V and tolerant to load-dump events up to 51 V) makes the TJA1044 directly compatible with 12 V automotive battery rails without external protection components. When designing with the TJA1044GT-3Z, place a 100 nF decoupling capacitor on VCC as close as possible to the pin, and follow the datasheet's recommendations on CAN bus termination (typically 120 ohm at each end of the bus). Do not leave the STB pin floating; tie it to GND for normal operation or to the microcontroller for wake/sleep control. Always respect the maximum bus voltage rating, especially in 24 V truck systems where the load-dump transient can exceed 51 V if the suppression is inadequate.

TJA1044GT/1Z - High-Speed CAN Transceiver | NXP Semiconductors

The NXP Semiconductors TJA1044GT/1Z is a high-speed Controller Area Network transceiver with standby mode, selective wake-up capability, and autonomous standby operation. It is packaged as an 8-pin SO device and is designed to interface a CAN protocol controller with a physical two-wire CAN bus. The device is positioned for automotive body and safety applications requiring differential CAN transmit and receive functions. Its core role is to convert digital TXD and RXD signaling between a host controller and the differential CANH and CANL bus conductors while supporting low-power network management. A CAN transceiver is an interface IC within the broader physical-layer network-device hierarchy. A CAN controller processes messages and protocols, while the transceiver connects that controller to the physical bus through differential transmit and receive paths. NXP describes the TJA1044 as part of the Mantis family of high-speed CAN transceivers, designed for 12 V automotive applications and optimized around electromagnetic compatibility performance. The supplied manufacturer information identifies several functional attributes. Selective wake-up allows the device to react to recognized CAN activity instead of requiring continuous full-power operation. Standby mode provides a controlled low-power state, while autonomous standby operation allows the transceiver to manage its own power-related behavior. The 8-SO package supports compact surface-mount implementation. The manufacturer also identifies differential transmit and receive capability, enabling communication with a CAN controller over the automotive two-wire network. Operationally, the TJA1044 belongs to a high-speed CAN physical-layer product family rather than a protocol controller or bus arbitration device. It does not independently generate CAN frames; instead, it provides the electrical interface between logic-level controller signals and the differential bus. This separation allows the same host microcontroller or dedicated CAN controller to handle frame construction, arbitration, error management, and higher-level diagnostics while the transceiver manages bus-level electrical signaling. Typical uses include automotive body controllers, body-domain modules, comfort systems, safety-related electronic modules, gateway interfaces, and distributed vehicle networks. It is also relevant to industrial CAN equipment that needs a compact high-speed bus interface and a transceiver designed specifically for 12 V automotive electrical environments. In a complete design, the TJA1044 is paired with a host processor or CAN controller, bus termination, transceiver supply decoupling, and a CANH/CANL physical network. A key design consideration is the distinction between a same-footprint alternative and a truly validated replacement. Ordering-code variants and devices from other manufacturers can share an SOIC-8 footprint while differing in VIO support, supply range, standby behavior, temperature grade, EMC performance, or wake-up logic. Engineers should compare the complete NXP datasheet, PCB footprint, exposed-pad requirements, transceiver mode inputs, bus fault behavior, and firmware assumptions before substituting a component. This page consolidates manufacturer positioning, distributor records, verified source links, strict drop-in candidate information, and application-oriented design guidance. It also identifies where electrical ratings, pricing, lifecycle status, and package details require confirmation rather than presenting unsupported assumptions as product facts.

The NXP Semiconductors TJA1044GTJ is a high-speed CAN transceiver with standby mode, providing one transmitter and one receiver for a two-wire Controller Area Network bus. It supports a data rate of 5 Mbps and a 4.75 V to 5.25 V supply range in an 8-pin SOIC surface-mount package. The transceiver includes a 300 mV receiver hysteresis and is intended to connect a CAN protocol controller to the physical CAN network. A CAN transceiver is the physical-layer interface within a Controller Area Network system. The protocol controller creates and interprets CAN frames, while the transceiver converts those digital signals into differential bus levels and converts received bus levels back into controller-compatible logic. CAN transceivers therefore belong to the hierarchy of interface IC, communications transceiver, CAN interface, and semiconductor. Verified device data identifies the TJA1044GTJ as a one-driver, one-receiver, half-duplex 5 Mbps CAN interface with standby mode. Its 8-SOIC package supports automated surface-mount assembly, while the 300 mV receiver hysteresis provides noise margin around the receiver switching threshold. The 4.75 V to 5.25 V supply range permits use with conventional regulated 5 V digital systems. The TJA1044 belongs to NXP's Mantis high-speed CAN transceiver family and targets automotive networking. Its CANH and CANL bus-side interface must operate with the protection, termination, routing, and common-mode strategy required by the target vehicle network. Standby mode provides a means to reduce participation when the node does not require normal bus operation, but the system designer must confirm all wake-up behavior from the complete manufacturer documentation. Typical uses include body-control modules, automotive comfort systems, powertrain-adjacent controllers, gateway nodes, and industrial CAN equipment connected to 5 V logic. A CAN controller, crystal or clock source, decoupling network, bus termination, and connector are normally placed around the transceiver according to the reference design and system requirements. Design care should focus on bus-layout symmetry, short ground returns, correct split termination, compliant common-mode protection, and validation of standby-state timing. The CAN wires should not be routed as ordinary unprotected low-speed signals because fast edges and faults can exceed expectations outside the transceiver operating envelope. This page consolidates verified manufacturer and distributor information, separates known TJA1044GTJ characteristics from missing data, and evaluates candidate replacements conservatively. It is intended to add sourcing context and design guidance without presenting unsupported electrical limits or unverified cross-brand pin compatibility as fact.

TJA1044GTKZ - High-Speed CAN Transceiver, 5Mbps, HVSON-8 | NXP

The NXP TJA1044GTKZ is a high-speed Controller Area Network (CAN) transceiver from the Mantis family, providing the physical interface between a CAN protocol controller and the two-wire CAN bus, packaged in an 8-pin HVSON (3mm x 3mm) with an exposed thermal pad. It supports data rates up to 5 Mbps in CAN FD (Flexible Data-rate) networks and features a low-power Standby mode for quiescent current reduction when the bus is idle. A CAN transceiver is a physical-layer device that converts the digital transmit/receive signals of a CAN controller into the differential voltage levels required by the CAN bus standard (ISO 11898-2:2016). As a member of the high-speed CAN transceiver category, the TJA1044 sits at the bottom of the in-vehicle networking hierarchy: microcontroller -> CAN controller (typically integrated in the MCU) -> CAN transceiver (TJA1044) -> differential CAN bus. It is foundational to automotive and industrial communication networks where reliable, deterministic messaging is critical. Key features include a very low-current Standby mode with remote wake-up via a wake-up pattern (WUP) recognition per ISO 11898-2:2016, bus-fault detection and protection against -27 V to +40 V automotive transients, thermal shutdown, and an undervoltage detector on VCC and VIO. The transceiver operates from a single 5 V supply (VCC), with a separate VIO pin for direct interfacing to 3.3 V or 5 V microcontrollers without level shifters. The TJA1044 uses a fully ISO 11898-2:2016 compliant driver and receiver with dominant-timeout protection to prevent a faulty controller from permanently clamping the bus. The integrated slope-control function (via the STB/NRM pin) and low Electromagnetic Emission (EME) design simplify EMC compliance in dense automotive modules. The exposed thermal pad (EP) of the HVSON-8 package is essential for dissipating heat during sustained dominant transmission, ensuring reliable operation across the -40 C to +150 C automotive Grade-1 temperature range. Typical applications include body control modules, gateway ECUs, powertrain ECUs, battery management systems (BMS), ADAS sensor ECUs, industrial CAN nodes, and telematics control units. Its 5 Mbps capability makes it suitable for CAN FD networks carrying larger payload data, while Standby mode enables CAN partial networking for ECUs that must wake only on recognized WUP messages. When designing with the TJA1044, terminate the bus with a 120 ohm split-terminator network (RT = 60 ohm + 60 ohm + 4.7 nF common-mode cap) rather than a single 120 ohm resistor, which improves EMI/ESD immunity and DC stability. Place a 100 nF decoupling capacitor close to VCC and ensure the exposed pad is soldered to a sufficient copper pour for thermal dissipation.

TJA1044T - 1 Mbit/s CAN Transceiver with Standby | NXP | SO-8

The NXP Semiconductors TJA1044T is a high-speed CAN transceiver with standby mode, specified for data rates up to 1 Mbit/s, that interfaces a CAN protocol controller to a physical two-wire CAN bus. The device belongs to the NXP Mantis family of high-speed CAN transceivers and is packaged in a compact 8-pin SO (SOIC-8) surface-mount package with low sleep-mode current consumption for energy-conscious automotive and industrial designs. A CAN transceiver, also called a CAN physical-layer interface or CAN PHY, sits between a host microcontroller's CAN controller and the differential CANH/CANL bus wiring. It converts the controller's logic-level TXD signal into a differential dominant/recessive bus waveform and converts the received differential bus state back into a logic-level RXD output. Within the device hierarchy, a CAN transceiver is a bus interface IC, which is a subcategory of interface ICs and, more broadly, of integrated circuits. The TJA1044 family differentiates itself from earlier generations through an integrated standby (sleep) mode that lets the node hold a defined bus state while drawing minimal supply current, and through transmitter characteristics tuned for automotive EMC robustness. The TJA1044T is specified for 1 Mbit/s operation, which matches classic high-speed CAN traffic used by body controllers, powertrain gateways, comfort systems, and industrial CANopen-style field buses. Variants of the family are additionally specified with loop-delay symmetry parameters, supporting CAN FD fast-phase operation up to 5 Mbit/s on those derivatives. In the TJA1044T the digital interface runs from a single 5 V supply with a separate VIO pin in packages that provide one, allowing the logic side to be referenced to 3.3 V or 5 V system levels. The standby input pin places the device into a low-power state where the bus driver is de-asserted so the node does not disturb the bus while asleep, which is critical for modules that must wake periodically or remain quiescent during vehicle key-off. Typical deployments include automotive body and comfort control modules, engine and transmission control units, electric vehicle powertrain controllers, industrial automation gateways, elevator and building automation controllers, and aftermarket CAN diagnostic adapters. Because the transceiver is the physical-layer element closest to the harshest environment in the design, correct bus termination, common-mode margin, and PCB layout matter as much as the controller firmware. When integrating the TJA1044T, provide the standard 60 ohm termination only at the two physical ends of the bus, keep CANH and CANL routing as a tight, length-matched differential pair away from switching nodes, and confirm that the standby control signal defaults to the correct state at reset so the node never blocks the bus during startup.

TJA1044T/1Z - High-Speed CAN Transceiver, 1Mb/s, 8-SO | NXP

The NXP TJA1044T/1Z is a high-speed Controller Area Network (CAN) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus in an 8-pin SO (SOIC-8) package. It supports CAN data rates up to 1 Mbit/s and reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s, and it implements the CAN physical layer defined in ISO 11898-2:2024 third edition and SAE J2284-1 to SAE J2284-5. A CAN transceiver is the physical-layer device that sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wires. It translates the controller's digital transmit (TXD) and receive (RXD) signals into the dominant/recessive differential voltage levels required by the ISO 11898 standard, while providing ESD protection, bus fault tolerance, and common-mode rejection. The TJA1044 belongs to the higher-level hierarchy: CAN transceiver → automotive network interface IC → in-vehicle networking → automotive power management, and is widely used wherever an MCU must communicate over a robust, differential bus. Key features include very low standby current with wake-up capability, an internal slope-control mechanism that reduces electromagnetic emissions, and excellent EMC performance that allows removal of common-mode chokes. The device provides high ESD robustness on the bus pins (typically ≥8 kV HBM) and is specified over the -40 °C to +150 °C automotive temperature range. A dedicated standby mode reduces quiescent current while still monitoring the bus for wake-up activity, making the TJA1044T/1Z well suited for always-on automotive networks. The implementation uses NXP's proven BiCMOS process and an advanced differential transmitter with tightly controlled edge symmetry to minimise radiated emissions. Combined with an integrated split-pin concept (the SPLIT output stabilises the recessive common-mode voltage of the bus) and a wide common-mode range for CANH/CANL, the design delivers high ElectroMagnetic Compatibility (EMC) margins even on long cable backbones. Typical applications include high-speed CAN body and chassis networks, powertrain ECUs (where the part operates at -40 °C to +150 °C), CAN nodes for body-control modules (BCMs), gateway nodes between CAN and CAN FD buses, and industrial CAN-FD field-bus nodes in vehicles, trucks, agricultural equipment, and forklifts. When designing with the TJA1044T/1Z, place a 100 nF decoupling capacitor as close as possible to the VCC pin and follow the bus-layout recommendations in the manufacturer datasheet. A split termination (typically 60 Ω between CANH and CANL plus two 30 Ω resistors to ground through a 4.7 nF capacitor, or referenced to the SPLIT pin) significantly improves EMC behaviour and should not be omitted on long stubs. This page combines manufacturer-anchored specifications, same-family drop-in alternatives, comparison data and PCB-level design notes that go beyond a single distributor product listing.
