TJA1055T - 125 kBd Fault-Tolerant CAN Transceiver | NXP | SOIC-14
The NXP Semiconductors TJA1055T is an enhanced fault-tolerant CAN transceiver that interfaces a CAN protocol controller with the physical CANH and CANL bus wires, intended for low-speed in-vehicle communication up to 125 kBd in passenger cars, and it is supplied in a 14-pin SOIC (SOP-14) surface-mount package. A CAN transceiver is the physical-layer device in a Controller Area Network link. It sits between the CAN protocol controller inside a microcontroller and the differential bus wiring, converting controller logic levels into balanced bus-line signals and, in the opposite direction, converting received bus states into a clean logic-level receive output. In the classification hierarchy it is an interface IC, specifically a CAN interface or CAN bus transceiver, a member of the broader transceiver and interface IC family used in automotive and industrial communication networks. Key features of the TJA1055T include its enhanced fault-tolerant bus-line interface, its optimization for low-speed in-car communication, and its pin-to-pin compatibility with the earlier TJA1054 and TJA1054A devices, which allows an upgrade of an existing design without a board change. The fault-tolerant architecture is the defining improvement over the predecessor family, adding protection against faults that occur on the bus lines during operation. Technically, the device operates with the standard differential CAN signalling scheme in which the two bus lines are dominant and recessive states rather than fixed levels. Because the TJA1055T is specified for low-speed networks up to 125 kBd, it is intended for body, comfort and convenience sub-networks rather than for powertrain or chassis high-speed CAN links, where devices rated for 1 Mbit/s or more are normally chosen. The 14-pin SOIC package is a standard surface-mount footprint that simplifies assembly and rework in automotive electronics manufacturing. Typical applications include body control units, door and seat modules, climate control units, window and lighting controllers, passenger-comfort CAN sub-networks, vehicle diagnostic interfaces, low-speed CAN gateways for industrial and building systems, and CAN bus test and monitoring equipment. When laying out the design, place the transceiver close to the bus connector, keep the CANH and CANL traces short and matched, provide the required bus termination resistors at the physical ends of the segment, and decouple the supply pins close to the device to limit conducted noise on the bus. Confirm that the transceiver variant selected matches the supply and bus configuration of the target network before releasing the layout. This page consolidates the manufacturer description, verified distributor listings, drop-in replacement candidates and practical integration guidance for the TJA1055T in one place, so engineers can qualify the part and plan a sourcing strategy without searching through multiple listings and cross-reference tools.
TJA1055T/1J - 125 kBd Fault-Tolerant CAN Transceiver
NXP Semiconductors TJA1055T/1J is an enhanced fault-tolerant Controller Area Network transceiver for low-speed data links up to 125 kBd. It operates from a 4.75 V to 5.25 V supply and is packaged in a 14-pin SOIC for surface-mount assembly. The device connects a CAN protocol controller to the physical CANH and CANL bus conductors while providing differential transmit, receive, and fault-tolerance functions. A CAN transceiver is the physical-layer interface between a digital CAN controller and the wired CAN network. The TJA1055 family belongs to the interface-IC hierarchy and is specifically optimized for in-car low-speed communication, where its 125 kBd target complements higher-speed CAN controller and transceiver families. Its enhanced fault tolerance helps maintain operation when the bus is shorted to ground, shorted to the supply, or open-circuit, subject to the detailed protection and operating conditions stated by NXP. Key verified characteristics include a 125 kBd low-speed CAN application target, a 4.75 V minimum supply, a 5.25 V maximum supply, and a 14-pin SOIC package. NXP identifies the TJA1055 as pin-to-pin compatible with the TJA1054 and TJA1054A. Distributor listings also identify TJA1055T/1J as an automotive CAN interface available in tape-and-reel ordering. The transceiver should be placed near the CAN bus connector, with its CANH and CANL pins connected to the protected bus wiring and its TXD and RXD pins connected to the CAN controller. Because the device is intended for passenger-car and other low-speed CAN links, system designers should verify timing, termination, bus topology, logic levels, and protection requirements against the manufacturer datasheet before production release. The TJA1055T/1J is suitable for automotive body electronics, comfort modules, diagnostic equipment, sensor nodes, and other 125 kBd CAN applications. Its principal design consideration is that CAN bus behavior depends on termination, wiring, common-mode conditions, and transceiver protection. A CAN bus should not be treated as a generic communication line; the selected transceiver, controller, and network implementation must be validated together. This page combines verified manufacturer and distributor information, package and ordering details, and application guidance for engineers evaluating a SOIC-14 CAN physical-layer interface.
TJA1055T/2Z - 125 kBd Fault-Tolerant CAN Transceiver | NXP
The NXP Semiconductors TJA1055T/2Z is an enhanced fault-tolerant Controller Area Network transceiver intended for low-speed automotive applications up to 125 kBd. It provides a physical-layer interface between a CAN protocol controller and the CAN bus conductors, uses a 14-SO package, and is supplied in tape-and-reel packaging. According to the NXP product information, its budgetary price is $1.15 USD at a quantity of 1,000 and its indicated lead time is 10 weeks. A CAN transceiver is an interface IC that connects a host controller to a differential CAN network. It belongs to the communication interface hierarchy: CAN transceiver > bus transceiver > interface IC > semiconductor. Unlike a generic transceiver, this device is designed around the electrical behavior and fault tolerance requirements of low-speed CAN systems, where dependable operation during wiring faults and disturbed bus conditions is important. Key documented features include enhanced fault-tolerant CAN operation, support for data rates up to 125 kBd, and use in passenger-car CAN networks. The verified distributor records also identify the device as a one-channel, half CAN-bus transceiver in a 14-SO package. The NXP product page identifies TJA1055T as active and lists reel-reel packing with a minimum package quantity and minimum order quantity of 2,500 pieces. The TJA1055T/2Z performs the physical signaling required between the CAN controller and the bus while providing the fault-tolerance behavior expected in automotive environments. Its use of a dedicated bus interface allows the controller to send and receive frames without implementing analog bus-level signaling directly. Detailed thresholds, loopback behavior, supply current, and absolute maximum ratings remain [DATA_NEEDED: complete electrical characteristics] because they were not included in the supplied verified records. Typical uses include passenger-car body and comfort systems, door modules, climate-control controllers, lighting controllers, instrument clusters, and other low-speed CAN nodes. It is most appropriate where the network operates at 125 kBd or below and the design requires a dedicated high-reliability CAN physical-layer device rather than a general-purpose differential transceiver. When designing a PCB around the TJA1055T/2Z, verify the complete NXP datasheet pinout, transceiver termination requirements, supply decoupling, and bus-fault behavior before layout release. The supplied search records establish the 14-SO package designation but do not expose a verifiable numbered pin table, so this page does not infer pin names or connectivity. Maintain the manufacturer-specified CAN bus topology and provide the required local decoupling and protection appropriate to the vehicle network.
TJA1055T/3/1J - 125 kBd Fault-Tolerant CAN Transceiver | NXP

It is designed for passenger-car body and comfort electronics where fault tolerance and low-speed in-vehicle networking are important. A CAN transceiver is the physical-layer interface between a CAN protocol controller and the differential CAN bus. It converts controller logic signals into CANH and CANL bus activity and converts differential bus voltage into a receive signal. Positioned within the hierarchy of CAN interface ICs, transceiver ICs, interface ICs, and semiconductors, the TJA1055T provides the electrical interface required to connect digital controllers to a robust in-vehicle communication network. The TJA1055T/3/1J provides operation at data rates up to 125 kBd, differential receive and transmit functions, and sleep or standby operating modes for reduced power consumption. Its supply-voltage coverage supports systems operating from 5 V, 9 V, 12 V, 15 V, 18 V, 24 V, and 28 V environments. The /3 order-code variant provides a 3 V VIO interface, allowing compatibility with controllers or logic domains using a lower supply voltage. The device uses differential bus signaling to provide common-mode rejection and improve robustness against noise found in vehicle electrical environments. Its fault-tolerant design is intended for low-speed CAN networks in passenger cars rather than high-bandwidth automotive Ethernet or high-speed CAN FD systems. The 14-pin SO package supports compact surface-mount assembly while exposing the controller interface, bus interface, power, ground, and control connections required by the device architecture. Typical applications include vehicle body-control modules, door and seat controllers, climate-control interfaces, lighting controllers, comfort systems, and distributed low-speed passenger-car networks. The combination of a 125 kBd maximum data rate, broad supply range, sleep or standby support, and 3 V VIO option makes the TJA1055T/3/1J appropriate where a 3.3 V controller must communicate with a conventional 12 V or 24 V vehicle CAN network. When designing the PCB layout, treat CANH and CANL as a controlled-impedance differential pair routed as symmetrically as practical, with a continuous return path beneath the pair. Keep the transceiver close to the bus connector or bus-header, minimize stub branches, and follow the grounding and decoupling recommendations in the manufacturer datasheet. Component values and layout distances not present in the supplied source extract remain unverified and must be confirmed from the complete NXP datasheet before release. This page consolidates the verified NXP product information, distributor listings, order-code distinctions, and package data for TJA1055T/3/1J. It also distinguishes confirmed drop-in references from unsupported cross-brand equivalents, highlights verified design parameters, and clearly identifies pricing, pin-mapping, and detailed electrical values that still require confirmation.
TJA1055T/3/2Z - 125 kbit/s Fault-Tolerant CAN Transceiver | NXP | SO-14
The NXP Semiconductors TJA1055T/3/2Z is an enhanced fault-tolerant CAN transceiver for low-speed Controller Area Network buses up to 125 kbit/s, packaged in a 14-pin SO (SOIC-14) surface-mount package with an exposed ground-pad-style land pattern. It accepts supply rails of 5 V, 9 V, 12 V, 15 V, 18 V, 24 V and 28 V, and provides a single differential transmit and receive channel (1/1, half duplex) with sleep and standby modes for low-current parked vehicles. A CAN transceiver is the physical-layer interface between a CAN protocol controller and the two-wire differential bus. It converts the controller's logic-level TXD and RXD signals into balanced bus levels, and returns a filtered digital receive signal. The TJA1055 belongs to the fault-tolerant CAN transceiver family, where the bus driver survives shorted-bus and reversed-battery conditions that would damage a conventional high-speed transceiver. Key characteristics include operation up to 125 kbit/s, an enhanced fault-tolerant transmit driver, a receive filter with extended glitch rejection, low-current sleep and standby operating modes, and AEC-Q100 qualification for automotive applications. The device is pin-to-pin compatible with the earlier TJA1054 and TJA1054A, which allows existing low-speed CAN body, comfort and diagnostic modules to be updated without a layout change. Internally the device separates the controller interface from the bus interface so that the bus-side driver can withstand faults independently of the logic side. A dedicated sleep input and internal mode control let a body control module wake the transceiver only when needed, reducing standing current in parked vehicles. The recessive and dominant output levels are defined to suit ISO 11898-2 style low-speed CAN networks. Typical uses include passenger-car door modules, seat and window controllers, climate control panels, body control units, diagnostic connectors, trailer modules and other 125 kbit/s CAN nodes in vehicles, plus industrial equipment that adopts low-speed CAN for cable-cost reduction. When laying out the board, place the bus transceiver close to the connector and keep the CANH and CANL traces short, matched in length and free of stubs, because the twisted pair carries a differential signal whose balance determines noise immunity. The logic-side pins need short traces to the CAN controller and a solid ground reference, since the transceiver converts bus common-mode voltage into a single-ended logic output. This page consolidates manufacturer ratings, package details, drop-in alternatives, application guidance and layout notes so that engineers can evaluate the TJA1055T/3/2Z for a low-speed CAN node without rebuilding the data from multiple sources.
TJA1055T/C - 125 kBd Fault-Tolerant CAN Transceiver | NXP
The NXP Semiconductors TJA1055T/C is a fault-tolerant Controller Area Network transceiver intended to connect a CAN protocol controller to a physical CAN bus in passenger-car systems operating at data rates up to 125 kBd. It operates from a 4.75 V to 5.25 V supply and is offered in a 14-pin SO package. The device provides one CAN transmit driver and one CAN receive buffer for use with CAN-based control, monitoring, and diagnostic systems. A CAN transceiver is the physical-layer interface within a Controller Area Network. A CAN controller generates and interprets digital frames, while the transceiver converts controller signals into differential bus levels and converts differential bus signals back into logic-level receive data. The TJA1055T/C belongs to the CAN interface transceiver hierarchy, connecting network-interface ICs with the CAN bus wiring in automotive electronics. The TJA1055 is described by NXP as an enhanced fault-tolerant CAN transceiver. Its intended maximum signaling rate of 125 kBd suits low-speed passenger-car networks, while its 4.75 V to 5.25 V operating supply supports conventional 5 V CAN-controller systems. The 14-SO package also gives PCB designers a recognizable, surface-mount option for compact automotive and industrial control assemblies. Compared with the earlier TJA1054 family, the manufacturer describes the TJA1055 as an enhanced version with additional improvements. The fault-tolerant interface role allows a CAN node to maintain communication when bus faults occur within the application's specified operating limits. Designers should still verify fault behavior, termination requirements, bus topology, and controller compatibility against the complete manufacturer datasheet before production release. Typical uses include automotive body-control modules, passenger-compartment controllers, comfort systems, diagnostic interfaces, and other distributed electronic systems that exchange low-speed CAN messages. The TJA1055T/C can also support laboratory CAN-interface prototypes where a 125 kBd fault-tolerant physical layer is required and 5 V logic compatibility is appropriate. PCB implementation requires correct CAN routing, provision of the bus termination defined by the network design, and a stable 5 V supply. Place the transceiver and its associated decoupling close to the CAN connector and controller interfaces, and route the differential CAN_H and CAN_L pair together without unnecessary stubs. Confirm logic thresholds, loopback behavior, bus-fault recovery, and timing margins in the target system. This page combines the manufacturer's product identity, core electrical ratings, package information, application guidance, cross-reference findings, and practical design considerations. It also identifies which parameters require confirmation from the full TJA1055 data sheet, helping engineers move from part selection to a defensible PCB design without overlooking CAN-specific implementation details.
TJA1057BTK - High-Speed CAN Transceiver | NXP Semiconductors
The NXP Semiconductors TJA1057BTK 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 HVSON (3x3 mm) package with exposed pad. It supports data rates up to 5 Mbps (CAN FD capable), operates over a wide supply range of 4.75 V to 5.25 V, and is designed for high-speed CAN applications in the automotive industry. A CAN transceiver (also called a CAN bus driver/receiver) is a physical-layer IC that converts the differential digital signaling of a CAN protocol controller into the differential voltage levels required by the ISO 11898-2 CAN bus standard. It sits between a microcontroller's CAN module and the bus wires (CANH/CANL), providing immunity to common-mode noise and ESD protection. CAN transceivers belong to the broader family of interface ICs and are essential building blocks for in-vehicle networking, industrial automation, and any distributed control system that uses the CAN protocol. The TJA1057BTK delivers differential transmit capability to the bus with controlled slew rate, and differential receive capability with high common-mode rejection. It supports both Normal and Silent operating modes, where Silent mode disables the transmitter for listen-only diagnostics. The device is optimized for low electromagnetic emission (EME) and high electromagnetic immunity (EMI), meeting the stringent automotive requirements for CAN bus communication. Integrated thermal protection, bus dominant time-out, and under-voltage detection on VCC enhance system reliability. The 8-pin HVSON package (3x3 mm) with exposed thermal pad offers a very compact footprint suitable for space-constrained ECUs (Electronic Control Units). The exposed pad provides a low thermal resistance path to the PCB copper, allowing the IC to handle the bus fault conditions specified in ISO 11898-5 without derating. The TJA1057BTK is functionally identical to the TJA1057CT within the SOI3+ process family - they differ only in the VIO supply pin logic level handling. Typical applications include automotive body and comfort ECUs, infotainment CAN interfaces, industrial CAN nodes, building automation, and any embedded system requiring a robust, standardized CAN physical layer. In these use cases, the TJA1057BTK acts as the bus interface between a 3.3 V or 5 V microcontroller's CAN controller and the 12 V automotive CAN bus. A key design consideration is the bus termination: a 120 Ω resistor (or split 60 Ω + 60 Ω with capacitor) must be present at each end of the CAN bus segment. The HVSON exposed pad must be soldered to a copper pad of at least 1 mm² to ensure proper thermal performance under continuous bus fault conditions. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. The information gain comes from a structured cross-reference analysis combining the TJA1057 datasheet family, the obsolescence brief on TJA1050 replacements, and verified distributor stock data as of 2026-10-16.
TJA1057BTK-0J - 5Mbps CAN FD Transceiver, HVSON-8 | NXP
The NXP TJA1057BTK-0J is a high-speed CAN (Controller Area Network) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus. Housed in an 8-pin HVSON (3x3 mm) package with exposed pad, it supports data rates up to 5 Mbps and is qualified to AEC-Q100 Grade 1 for automotive applications. A CAN transceiver (also called a CAN bus transceiver or CAN interface IC) is a physical-layer device that converts the digital transmit/receive logic signals of a CAN protocol controller inside a microcontroller into the differential CANH/CANL bus signals required on the actual network. CAN belongs to the broader category of serial communication interface ICs, alongside RS-485, RS-232 and LIN transceivers. The TJA1057 family specifically targets high-speed classical CAN and CAN FD (Flexible Data-rate) networks used for powertrain, chassis and body electronics. Key features include a low electromagnetic emission (EME) common-mode choke design, high electromagnetic immunity (EMS), a low-power Standby mode with remote wake-up capability, and ±8 kV HBM ESD protection on the bus pins (per IEC 61000-4-2 on the bus pins, per datasheet). The transceiver operates from a 4.5 V to 5.5 V VCC supply, supports bus voltages from -27 V to +40 V, and provides a TxD dominant time-out for fail-safe behavior. The TJA1057BTK/0J variant carries the 'B' suffix (VIO supply pin present, allowing direct level-shifting to MCUs at 3.3 V or 5 V) and the 'TK' suffix indicating the 8-pin HVSON package with exposed pad. The /0J suffix designates the production ordering code (tape-and-reel packaging). Internally, the device uses a silicon-on-insulator (SOI) process (NXP SOI3+ family), which gives it excellent ESD and latch-up immunity versus older bulk-silicon CAN transceivers like the TJA1050. Typical applications include automotive body control modules (BCMs), gateway ECUs, instrument clusters, HVAC control units, transmission ECUs and industrial CAN nodes operating up to 1 Mbit/s in classical CAN or 5 Mbps in CAN FD networks. The transceiver interfaces directly to NXP S32K and most third-party automotive MCUs. When designing with this part, place the VCC decoupling capacitor (typically 100 nF) directly adjacent to pin 8 and connect the exposed pad (pin 0) to a large PCB ground plane for thermal dissipation and low-impedance return paths. Match the CANH/CANL bus termination to 120 Ω at the network ends to satisfy ISO 11898-2 and avoid signal-integrity issues at high bus loads.
TJA1057GT/1Z - High-Speed CAN Transceiver SOIC-8 | NXP
The NXP TJA1057GT/1Z is a high-speed CAN (Controller Area Network) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus, housed in an 8-pin SOIC (SO-8) package. Key specifications include ISO 11898-2:2016 conformance, data rates up to 1 Mbit/s on the TJA1057T variant with CAN FD support on other variants, and automotive-grade temperature operation. What is a CAN transceiver? A CAN transceiver is a physical-layer interface IC that converts digital transmit/receive logic signals from a microcontroller CAN controller into differential voltage signals on a two-wire CAN bus (CANH and CANL). It belongs to the hierarchy: CAN transceiver -> CAN interface IC -> Interface ICs -> Integrated Circuits. The transceiver also provides bus protection, fault tolerance (dominant/recessive clamping, TXD dominant time-out), and EMC/ESD robustness required in automotive environments. Key features of the TJA1057 include very low current consumption in standby and go-to-sleep modes with remote wake-up capability, an integrated VIO supply pin on /3 variants for direct interfacing with 3.3V and 5V microcontrollers, and an undervoltage detection on VCC and VIO supplies. The TJA1057 implements the CAN physical layer per ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, with the TJA1057T explicitly specified for data rates up to 1 Mbit/s. Architecturally, the device uses a differential transmit/receive path with slope control for low-EMI operation, an internal LDO for digital supply, and a sophisticated thermal protection scheme. Its split-pin output stage balances common-mode stability with low electromagnetic emissions, making it well-suited for automotive body, chassis, and powertrain networks. Typical applications include automotive body control modules, gateway ECUs, infotainment CAN nodes, industrial CAN automation nodes, and CAN-FD enabled instrument clusters. Its robustness against ESD (>6 kV HBM) and bus fault voltages (±58 V) makes it dependable in harsh electrical environments. When designing with this device, ensure proper bus termination with 120 ohm resistors at each end of the bus and a common-mode choke for EMI-sensitive applications. The TJA1057 requires careful placement of the VCC decoupling capacitor close to pin 1 to maintain supply stability during dominant-to-recessive transitions. This page synthesizes distributor pricing, drop-in alternative cross-references, and practical design notes not found in the manufacturer datasheet alone.
TJA1057GT/3J - 1 Mbit/s CAN Transceiver | NXP Semiconductors
The NXP Semiconductors TJA1057GT/3J is a high-speed CAN bus transceiver with differential transmit and receive capability, support for CAN data rates up to 1 Mbit/s, and a VIO input for direct interfacing with 3.3 V or 5 V microcontrollers. It is supplied in an 8-pin SOIC package. The device connects a CAN protocol controller to a physical two-wire CAN bus in automotive and industrial communication systems. A CAN transceiver is a physical-layer interface IC that converts logic-level controller signals into differential bus signals and converts received differential signals back into logic-level data. The TJA1057 belongs to NXP's Mantis family of CAN transceivers, placing it within the hierarchy of CAN interface IC, communication transceiver, interface IC, and semiconductor. Its high-speed differential operation allows a CAN controller and transceiver combination to communicate over a noisy wiring harness while preserving signal integrity. The principal feature of the /3 variant is its dedicated VIO supply connection. According to the manufacturer documentation, VIO should be connected to the microcontroller supply voltage, allowing the TXD and RXD interface levels to be adjusted for either 3.3 V or 5 V operation. This helps avoid unnecessary voltage-level conversion between the CAN controller and the physical bus transceiver. The TJA1057 family implements the CAN physical layer defined by ISO 11898-2:2016 and the SAE J2284-1 through J2284-5 specifications. TJA1057GT/3J provides one CAN channel and uses an 8-pin SOIC footprint identified as PDSO8 in distributor data. Its architecture separates the controller-facing digital interface from the differential CANH and CANL bus connection. The VIO domain supports integration with modern microcontrollers, while the bus side handles the higher-voltage signaling required by a wired CAN network. This division of voltage domains is central to correct PCB design because input, output, transceiver, and ground connections have different electrical roles. Typical uses include automotive body and chassis networks, industrial automation equipment, diagnostic systems, electric-vehicle subsystems, robotics, and embedded control platforms. It is particularly suitable when the CAN controller operates from 3.3 V while the surrounding vehicle or industrial network uses a conventional 5 V CAN physical layer. In these systems, the transceiver provides the physical interface while the CAN controller handles arbitration, framing, error management, and higher-level protocols. PCB implementation should follow the manufacturer's pin and layout guidance, including a common reference plane and a controlled return path beneath the bus connections. Decoupling and protection requirements should be evaluated against the actual vehicle or industrial network because external bus transients and ground offsets can exceed nominal logic-level conditions. The VIO connection must be referenced to the microcontroller supply, and unused or unused-after-configuration pins must not be left without consideration. This product record consolidates the verified NXP documentation, distributor availability, package information, lifecycle status, and same-family replacement information. It also highlights the practical distinction between the VIO-enabled /3 variant and other TJA1057 options so engineers can make a pin-compatible selection without confusing protocol support, interface voltage, or temperature-grade suffixes.
TJA1057GTJ - High-Speed CAN Transceiver, 1Mbps, 8-SO | NXP
The NXP Semiconductors TJA1057GTJ is a high-speed Controller Area Network (CAN) transceiver in the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus, delivered in an 8-pin SO (SOIC-8) surface-mount package. It supports data rates up to 1 Mbit/s, operates from a 4.75 V to 5.25 V supply, and is qualified for the -40 °C to +150 °C automotive temperature range. The TJA1057GTJ integrates differential transmit/receive capability, standby mode, and superior EMC and ESD performance versus earlier-generation transceivers. A CAN transceiver is the physical-layer (PHY) bridge between a digital CAN protocol controller (typically integrated into a microcontroller) and the differential CAN bus wiring in a vehicle or industrial network. Transceivers convert the controller's TX/RX logic-level signals into the ISO 11898-2 compliant differential bus levels, and they protect the controller from bus-level transients. The TJA1057GTJ belongs to NXP's Mantis family, which improved on the predecessor TJA1051/TJA1042 series by offering lower electromagnetic emissions and higher ESD robustness while maintaining pin compatibility. Key specifications include: 1 Mbit/s maximum data rate, 4.75 V to 5.25 V supply range, low-current standby mode, ISO 11898-2 conformance, bus pin ESD robustness of ±8 kV HBM (typical), and integrated thermal protection. The device is optimized for 12 V automotive systems and supports both normal and standby operation modes. The SOIC-8 package offers a standard 3.9 mm body width suitable for reflow soldering in automotive PCB assemblies. Architecturally, the TJA1057 uses a silicon-on-insulator process node that allows the bus pins (CANH, CANL) to survive load-dump transients up to ±42 V typical without external protection, while maintaining low quiescent current in standby mode. The device includes slope control for reduced EMI, dominant-timeout protection, and a bus-dominant detection feature that prevents the controller from being locked in a dominant state if a wiring fault occurs. Typical applications include automotive body and powertrain CAN nodes, industrial CANopen networks, gateway ECUs, and any 5 V microcontroller-based system requiring an ISO 11898-2 compliant physical layer. It is widely used in BMS modules, HVAC controllers, instrument clusters, and ADAS sensor nodes where reliable high-speed differential communication is required. When designing with the TJA1057GTJ, place a 100 nF decoupling capacitor close to pin 8 (VCC) and respect the bus termination scheme (typically 120 Ω at each end of the CAN bus segment). The standby pin (STB) should be tied to GND through a pull-down or controlled by the host MCU; a high level puts the part into low-power standby with the bus monitor still functional. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including cross-references to TJA1057 family members and other 8-pin high-speed CAN transceivers.
TJA1057GTK - High-Speed CAN Transceiver, 1 Mbit/s, 8-HVSON | NXP
The NXP TJA1057GTK 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 a compact 8-pin HVSON (3x3 mm) package with an exposed thermal pad. It supports data rates up to 1 Mbit/s, operates from a 4.75V to 5.25V supply, and delivers differential transmit/receive capability required by automotive in-vehicle networks. The TJA1057GTK variant includes a standby mode for low-power operation and is optimized for superior electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance. A CAN transceiver is a physical-layer interface IC that converts the digital transmit (TXD) and receive (RXD) signals from a CAN controller into the differential CANH and CANL bus voltages defined by the ISO 11898-2 standard. Within the broader hierarchy, a CAN transceiver sits below the CAN controller (typically inside a microcontroller) in the Open Systems Interconnection (OSI) model and sits above the physical bus medium. Without a transceiver, a controller cannot meet the bus-level timing, drive strength, or fault protection that an automotive CAN bus demands. Key features include a low-current standby mode with remote wake-up via bus activity, thermal protection, bus-dominant time-out to prevent a stuck node from blocking the bus, and an undervoltage detection on the VCC supply. The HVSON-8 package features an exposed thermal pad that reduces junction-to-ambient thermal resistance, enabling AEC-Q100-qualified automotive operation across the -40C to +125C range. The TJA1057 is pin-compatible with the legacy TJA1050 footprint in SO-8 but uses the smaller, thermally enhanced HVSON-8 package in this GTK suffix variant. The transceiver uses a symmetric differential driver stage that minimizes electromagnetic emissions, and the receiver incorporates a wide common-mode range to tolerate ground shifts between nodes on long bus runs. An integrated slope-control resistor optimizes the rise/fall times of the CANH/CANL edges to balance emissions against bit-timing symmetry. Typical applications include automotive body control modules, gateway ECUs, infotainment CAN interfaces, industrial CANopen networks, and any 12V/24V automotive subsystem that communicates via CAN at speeds from 10 kbit/s to 1 Mbit/s. Designers select the TJA1057GTK when EMC performance and a small PCB footprint outweigh the need for the higher bus-fault voltage ratings of the TJA1055 or TJA1044. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin, keep the CANH/CANL traces short and symmetric with characteristic impedance near 120 ohm, and verify that the termination resistance at each end of the bus totals 120 ohm to prevent signal reflections. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical EMC/layout notes drawn from the NXP TJA1057 datasheet family, offering context the manufacturer product page alone does not provide.
TJA1057GTKZ - High-Speed CAN Transceiver | NXP
The NXP TJA1057GTKZ is a high-speed CANbus interface transceiver with one transmitter and one receiver in an 8-pin HVSON surface-mount package measuring 3 x 3 mm. It operates from a 4.75 V to 5.25 V supply, supports an operating temperature range of -40 °C to +150 °C, and provides half-duplex operation with a 300 mV receiver hysteresis. The Z-qualified ordering code is supplied on tape-and-reel packaging with a standard quantity of 6000 units. A CAN transceiver is an interface IC that connects a CAN protocol controller, normally implemented in a microcontroller, to the physical two-wire CAN bus. Its transmitter converts controller logic into the differential CANH and CANL bus signals, while its receiver converts those differential signals back into logic levels for the controller. The TJA1057GTKZ belongs to the NXP Mantis family of high-speed CAN transceivers designed for automotive applications. Key verified features include one CAN driver, one CAN receiver, half-duplex communication, 300 mV receiver hysteresis, and a regulated 5 V supply range of 4.75 V to 5.25 V. The wide -40 °C to +150 °C operating range supports demanding industrial and automotive environments. Its 8-HVSON package provides a compact 3 x 3 mm surface-mount footprint for space-constrained electronic control units. The TJA1057GTKZ provides the physical-layer interface required by a Controller Area Network controller. Differential signaling improves common-mode noise tolerance on the bus, while receiver hysteresis helps distinguish a valid logic transition from noise near the decision threshold. Half-duplex operation means the transmitter and receiver share the same physical CAN interface in accordance with the CAN bus architecture. Typical applications include automotive CAN networks, electronic control units, body-control modules, powertrain controllers, industrial vehicle communications, and embedded systems that connect a microcontroller or another CAN controller to a two-wire bus. Its small package also suits compact control boards where connector area and routing space are limited. Designers should verify CANH, CANL, ground, supply, and logic-interface connections against the current NXP datasheet and the selected controller's I/O levels. The 5 V supply must remain within 4.75 V to 5.25 V. Exact data-rate, loopback, bus-fault, and absolute-maximum ratings were not included in the retrieved source data and must be confirmed in the manufacturer documentation. This product page consolidates verified manufacturer and distributor information, practical application guidance, pricing references, and strict drop-in alternative screening. It distinguishes documented TJA1057GTKZ characteristics from unverified generic substitutes so engineers can make a safer, footprint-conscious sourcing decision.
TJA1057T - 1 Mbit/s High-Speed CAN Transceiver | NXP
The NXP Semiconductors TJA1057T is a high-speed CAN physical-layer transceiver, specified for data rates up to 1 Mbit/s and supplied in an 8-pin SO package. It provides the differential transmitter and receiver interface between a CAN protocol controller and a two-wire CAN bus, supporting automotive and industrial Controller Area Network designs. A CAN transceiver is an interface IC within the broader network-interface and automotive electronics hierarchy. It converts the controller's logic-level TXD and RXD signals into a differential bus waveform and converts received bus levels back into a logic signal. This physical-layer function complements the CAN controller, which implements frame handling, arbitration, error detection, and protocol processing above the physical layer. The verified NXP material identifies the TJA1057 as a member of the Mantis family of high-speed CAN transceivers. The implementation is described as compatible with the CAN physical layer defined in ISO 11898-2:2016 and SAE J2284-1 through SAE J2284-5. The TJA1057T itself is specified for communication rates up to 1 Mbit/s, while the datasheet states that enhanced timing characteristics permit reliable use during the CAN FD fast phase at rates up to 5 Mbit/s for other supported variants. Automotive network design is the principal use case because the device couples a CAN protocol controller to the vehicle's two-wire bus. It is also relevant to industrial automation, robotics, building automation, and embedded equipment that uses classic CAN rather than a proprietary differential bus. The 8-pin SO package permits compact implementation in conventional through-hole automotive and industrial controller boards. The central engineering considerations are bus termination, common-mode behavior, transceiver supply requirements, loop delay, and controller timing. A CAN bus normally uses 120-ohm termination at both ends of the network. The transceiver itself does not replace the external bus resistors, and system designers must also account for parasitic cable and stub effects when choosing bit rates, routing, and protection networks. Because the supplied excerpts do not expose the complete ordering table, electrical limits, pin names, thermal ratings, or verified distributor prices, those details remain explicitly unresolved rather than being inferred. Engineers should use the official NXP datasheet for the final schematic, component values, timing budget, and production release decisions. The TJA1057T is marked NRND on the official NXP product page, so long-term procurement should be confirmed before committing new designs. This page consolidates the verified manufacturer lifecycle status, CAN standards coverage, data-rate distinction, packaging information, and practical application guidance. It also identifies data gaps and avoids presenting unverified electrical specifications or unsupported drop-in replacements as verified facts.
TJA1057T/1Z - High-Speed CAN Transceiver | NXP SOIC-8
The NXP TJA1057T/1Z is a high-speed Controller Area Network (CAN) transceiver in the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus. Housed in an 8-pin SO (SOIC-8) package and specified for data rates up to 1 Mbit/s, it implements the CAN physical layer defined in ISO 11898-2:2024 third edition and SAE J2284-1 to SAE J2284-5, with additional timing parameters enabling reliable CAN FD fast-phase communication up to 5 Mbit/s. A CAN transceiver, also called a CAN physical-layer (PHY) chip, sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wires. It transmits and receives differential signals, controls the slope of the dominant-to-recessive transitions, and provides ESD protection and bus-fault tolerance. The TJA1057 belongs to the Mantis CAN transceiver lineage that supersedes the older TJA1050; its position in the hierarchy is: CAN transceiver -> CAN interface IC -> automotive communication IC -> semiconductor. Key features include very low-current standby mode with remote wake-up via bus activity recognition, high ESD robustness on the bus pins (typical >8 kV HBM), excellent electromagnetic compatibility (EMC) performance under both dominant and recessive states, and an integrated VIO supply pin (on related variants) allowing direct connection to 3.3 V microcontrollers. It supports an extended supply voltage range, an operating junction temperature range suitable for automotive under-hood environments, and a low-power sleep current that simplifies ECUs designed for quiescent-current budgets. The device translates a single-ended TXD logic input from the CAN controller into a differential CANH/CANL output, and converts the bus differential back to a single-ended RXD logic output. It offers an SPLIT output pin (on related variants) for stabilizing the recessive bus level in networks with many nodes. The TJA1057 is a successor to the TJA1050 and is pin-compatible with several Mantis-family derivatives, simplifying PCB reuse across OEM programs. Typical applications include automotive body control modules, CAN gateways and powertrain nodes, electric vehicle battery management system communication, industrial CAN-bus automation (CANopen, DeviceNet), and any application needing an ISO 11898-2 compliant differential CAN link to a microcontroller. The 1 Mbit/s nominal / 5 Mbit/s CAN FD fast-phase capability suits both classical CAN and modern CAN FD networks. When designing with this IC, place the bus-side ESD/TVS protection and common-mode choke as close to the CANH/CANL pins as possible, and provide a solid ground pour under the SOIC-8 body. Decouple VCC with at least 100 nF and 4.7 µF local capacitance. Match the bus termination: 120 Ω between CANH and CANL at each end of the bus, plus optional split termination (60 Ω + 60 Ω to ground) for improved EMC. This page synthesizes distributor pricing, NXP Mantis-family drop-in alternatives, and practical design notes not found in the standalone TJA1057 datasheet.
TJA1059TK - Dual HS-CAN Transceiver with Standby Mode | NXP
The NXP TJA1059TK is a dual high-speed CAN (HS-CAN) transceiver with integrated standby mode, housed in a 14-pin HVSON (3x4.5 mm) package. It provides the physical interface between a CAN protocol controller (typically a microcontroller) and the physical two-wire CAN bus, supporting differential transmit and receive signaling at data rates up to 1 Mbit/s as defined by ISO 11898-2:2024. A CAN transceiver is the physical-layer analog front-end of a Controller Area Network, the dominant in-vehicle serial bus. It level-translates digital TXD/RXD signals from a microcontroller (typically 3.3V or 5V CMOS logic) to the differential CANH/CANL bus signals that traverse the vehicle harness, while also providing bus protection, dominant bit clamping, and high-impedance bus isolation when unpowered. Key features of the TJA1059TK include two independent HS-CAN transceiver channels in a single package, a low-power standby mode activated through the STB pin, very low quiescent current in standby (suitable for battery-supplied ECUs during key-off), built-in dominant and recessive bit clamping, bus-pin protection against ±8 kV ESD (HBM) and ±6 kV IEC 61000-4-2, and a wide operating voltage range from 4.75 V to 5.25 V. Each channel is also designed to survive 12V load-dump and reverse-battery transients typical of automotive 12V nets. Architecturally, the TJA1059TK integrates two complete ISO 11898-2 transceivers with separate TXD/RXD lines from the host MCU, sharing the supply pins for both channels. The standby mode disables the entire receiver function for power savings while keeping a low-power bus monitor (variants differ). It is fabricated on a robust BiCMOS process optimized for 5V analog operation with high immunity to automotive EMI. Typical applications include automotive body control modules (BCMs), gateway ECUs between CAN segments, powertrain domain controllers, ADAS sensor fusion modules with dual CAN channels, CAN-based industrial sensor networks, and truck/bus chassis control units. The dual-channel integration saves PCB area in space-constrained ECUs and reduces BOM cost versus two discrete single-channel transceivers. When designing with this device, route the CANH/CANL traces as a 120-ohm-impedance differential pair with symmetric length matching. Place a 100nF decoupling capacitor close to VCC, and avoid ground loops by using a single-point low-impedance ground stitch near the transceiver. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on generic search engines - including same-package HVSON options and recommended companion MCUs for dual-channel CAN ECUs.
TJA1059TKJ - Dual 1Mbps CAN Transceiver | NXP
The NXP Semiconductors TJA1059TKJ is a dual high-speed CAN transceiver with a maximum data rate of 1 Mbps, two independent CAN channels, differential transmit and receive, and a 14-pin HVSON package measuring 3 mm by 4.5 mm. It is designed to interface a CAN protocol controller in a microcontroller with a physical two-wire CAN bus. A CAN transceiver is an interface IC between the digital CAN protocol controller and the physical differential bus. It converts controller logic into high-speed differential CAN signals and converts received bus levels into digital receive data. The TJA1059 therefore belongs to the hierarchy CAN transceiver → network interface IC → integrated circuit, and is intended for automotive and truck electronics. Key features include two CAN channels, high-speed operation up to 1 Mbps, standby mode, differential signaling, and a 5 V automotive supply context. The dual-channel architecture allows one controller or network node to serve two independent CAN buses or to expose two physical interfaces. Its surface-mount HVSON construction supports compact automotive electronics while its exposed pad assists thermal performance when the package layout is designed correctly. Technically, the transceiver separates the CAN transmit, receive, and standby functions within a robust physical-layer interface. Differential bus signaling improves noise immunity in vehicle environments, while standby mode can reduce activity when the interface is not required. Designers must still validate signal timing, bus termination, grounding, electromagnetic compatibility, and thermal conditions against the complete vehicle or industrial network architecture. Typical applications include automotive body and comfort controllers, truck electronics, CAN gateways, infotainment modules, engine or chassis control units, and industrial vehicle networks. The two channels are useful where a controller needs dual CAN connectivity without using two separate single-channel transceiver packages. A critical design consideration is preserving the exposed-pad thermal and electrical layout recommended by NXP. CAN bus traces should be routed as a controlled differential pair, with termination placed only at the physical ends of the bus. Standby-control polarity and timing must be verified in the system-level state machine. This page consolidates the verified NXP datasheet description, distributor identification, package information, price reference, and application guidance for engineers evaluating the TJA1059TKJ.
TJA1083TTJ - 10Mbit/s FlexRay Transceiver | NXP

Automotive qualification is listed by Arrow, while detailed AEC-Q100 qualification status and grade are not supplied in the verified excerpts. Typical uses include automotive FlexRay controller interfaces, body and chassis control modules, gate controllers, sensor nodes, power-distribution controllers, and other ECUs connected to a FlexRay backbone. The device handles the physical bus termination, signal transmission, reception, and common-mode interface functions described in the manufacturer documentation, while protocol and arbitration remain the responsibility of the associated FlexRay controller. Designers should verify the complete pin configuration, electrical limits, termination requirements, exposed thermal needs, and system-level bus topology against the manufacturer datasheet before layout release. The TSSOP package is compact, but its lead pitch and automotive operating requirements demand careful PCB escape routing, clean return paths, and controlled supply bypassing. Distributor listings also show a typical factory lead time of approximately 70 days, so procurement planning should include that stated interval. This page consolidates the verified manufacturer description, distributor availability details, package information, and engineering guidance for engineers evaluating a 10 Mbit/s FlexRay physical-layer transceiver. It does not infer unreleased specifications or substitute similarly named interface devices without verified pin compatibility.

It is used where an electronic control unit needs deterministic communication with other FlexRay nodes through a star-coupled network. The TJA1086HNJ is identified by distributor listings as a 1TX/1RX FlexRay transceiver-class device rated for 10 Mbps and supplied in a 44-pin HVQFN package with an exposed pad. Its automotive qualification is indicated by the Arrow listing, which identifies the part as AEC-Q100 automotive. The package and exposed-pad construction are important for thermal design and PCB layout, while the two-branch architecture is important when planning network topology. The TJA1086 can be used in automotive ECUs, gateway modules, body controllers, powertrain controllers, and other FlexRay nodes. Its dedicated communication-controller interface allows integration into an ECU, while TRXD0 and TRXD1 permit multiple TJA1085 or TJA1086 devices to increase the number of branches in a network. The supplied search data does not provide complete electrical limits, pin names, package dimensions, or absolute maximum ratings, so those values must be confirmed in the manufacturer datasheet before design release. For PCB implementation, preserve the manufacturer’s recommended HVQFN land pattern, exposed-pad connection, decoupling, and return-path arrangement. Keep FlexRay traces short and controlled, provide the specified termination and protection networks, and verify signal integrity with the intended communication-controller configuration. Do not infer pin compatibility from a similar package name; verify every pin, supply requirement, and timing parameter against the TJA1086 datasheet. This page consolidates verified distributor identification, FlexRay functionality, package information, sourcing links, and engineering-selection guidance. It distinguishes verified facts from parameters that require datasheet confirmation, helping engineers identify whether the TJA1086HNJ fits an automotive FlexRay star-coupler design before requesting detailed technical documents.
TJA1100HN - 100BASE-T1 Automotive Ethernet PHY | NXP | QFN-36
The NXP Semiconductors TJA1100HN is an IEEE 100BASE-T1 compliant single-port Automotive Ethernet PHY transceiver housed in a 36-pin HVQFN (QFN-36) package with exposed thermal pad. It supports 100 Mbit/s transmit and receive capability over a single unshielded twisted pair (UTP) cable for at least 15 m, optimized for automotive Ethernet backbones and sensor links in advanced driver assistance systems (ADAS).

The NXP Semiconductors TJA1100HNZ is an IEEE 100BASE-T1-compliant single-port Automotive Ethernet PHY transceiver supporting 100 Mbit/s transmit and receive operation over at least 15 m of unshielded twisted pair in a 36-pin HVQFN package. It is designed for automotive Ethernet links in IP cameras, driver-assistance systems, and backbone networks. A 100BASE-T1 PHY is a physical-layer interface IC that converts digital Ethernet data into electrical signals for a single twisted-pair cable and converts received signals back into digital data. It sits between an Ethernet MAC or automotive ECU and the physical cable. The TJA1100HNZ therefore belongs to the automotive network interface hierarchy: Ethernet controller, PHY transceiver, 100BASE-T1 interface, and physical-layer semiconductor. Key verified features include one Ethernet PHY port, 100 Mb/s operation, MII and RMII host interfaces, 3.3 V supply operation, operation from -40°C to +125°C, and AEC-Q100 automotive qualification. The device supports cable lengths of at least 15 m, helping it address compact vehicle wiring environments while reducing cable weight compared with conventional higher-channel-count Ethernet links. The TJA1100HNZ integrates the analog PHY and digital host-side interface needed for a 100 Mbit/s automotive Ethernet connection. Its MII and RMII interfaces provide compatibility with different controller arrangements, although the selected host interface, clocking, and software configuration must be checked against the complete system design. The 3.3 V operating supply is suitable for automotive electronic control units where low-voltage digital rails are common. Typical applications include IP camera links, driver-assistance systems, automotive backbone Ethernet, vehicle infotainment networks, and other in-vehicle Ethernet nodes. The single-pair cable architecture can simplify vehicle wiring compared with multi-pair Ethernet, while the automotive temperature rating and AEC-Q100 qualification support harsh operating environments. When laying out a TJA1100HNZ PCB, preserve the recommended high-speed copper connections and provide clean power and ground planes around the PHY. Differential pair routing, impedance control, return-path continuity, and separation from noisy switching circuits are essential because cable-side signal integrity affects link reliability. The supplied data confirms a 36-pin HVQFN package, but individual pin names and detailed layout values require the NXP datasheet.
TJA1102HN/0Z - Dual 100BASE-T1 Automotive Ethernet PHY | NXP
NXP Semiconductors TJA1102HN/0Z is a dual-port IEEE 100BASE-T1 automotive Ethernet physical-layer transceiver that supports 100 Mbit/s transmit and receive operation in a 56-pin HVQFN 8 x 8 mm package.

Unlike conventional multi-pair Ethernet, 100BASE-T1 carries 100 Mbit/s over one twisted pair, reducing wiring weight while supporting vehicle communication networks. The principal benefits of the TJA1102HN/0Z are its two-channel architecture, IEEE 100BASE-T1 compliance, 100 Mbit/s data rate, and automotive qualification. The exposed pad in the 56-HVQFN package provides a thermal and electrical land pattern on the PCB. Its sleep and wake-up forwarding function allows network activity to resume without requiring a separate switch, MAC, or host action for forwarding, supporting low-power vehicle-network architectures. Technically, the device combines two automotive Ethernet channels in one package and provides the physical-layer interface required by an IEEE 100BASE-T1 network. NXP identifies the TJA1102 as a highly integrated dual-port PHY and notes that it is fully qualified for automotive applications. Detailed electrical limits, pin functions, transceiver timing, EMC limits, and thermal metrics are not included in the supplied distributor extracts and must therefore be confirmed in the manufacturer documentation before schematic release. Typical uses include vehicle infotainment systems, in-vehicle Ethernet backbones, automotive domain controllers, zonal controllers, telematics units, advanced driver-assistance systems, and other ECUs that exchange data over single-pair Ethernet. The dual-channel configuration can simplify PCB allocation when a controller requires two 100BASE-T1 links, while sleep and wake-up forwarding supports power-conscious network nodes that must react quickly to remote traffic. Designers should preserve the manufacturer's HVQFN land pattern, thermal-pad layout, and reference-design stack-up rather than treating the part as a generic QFN. Automotive Ethernet also requires controlled return paths, appropriate connector and cable integration, validated EMC behavior, and careful separation from high-current or high-diversity radio-frequency systems. The precise pin assignments, recommended external network components, and layout clearances require the complete NXP datasheet. This page combines verified manufacturer and distributor information, package and lifecycle details, drop-in replacement research, a parameter-oriented comparison, and practical integration guidance. It distinguishes confirmed TJA1102HN/0Z attributes from specifications that still require validation from the complete manufacturer datasheet, helping engineers evaluate the device without treating missing data as guaranteed performance.
TJA1124BHG/0Z - Quad LIN Master Transceiver | NXP
The NXP Semiconductors TJA1124BHG/0Z is a quad LIN master transceiver with four LIN channels, integrated pull-up resistors, and four receive-data outputs, packaged in a 24-terminal DHVQFN measuring 3.5 mm by 5.5 mm by 0.85 mm. The device converts transmit data streams from a LIN commander protocol controller into shaped LIN bus signals and transfers received bus data to a microcontroller through RXD1 through RXD4. A LIN transceiver is an interface IC that connects a low-speed serial controller to a LIN bus. LIN, or Local Interconnect Network, is used for distributed automotive and industrial nodes that need inexpensive, robust communication over a single wired bus. Within the interface hierarchy, the TJA1124 belongs to the LIN transceiver class, automotive network interface IC category, and broader semiconductor product family. The TJA1124 integrates pull-up resistors for the four LIN commander outputs, reducing the number of external components required in a LIN bus arrangement. Its four-channel architecture lets one controller package serve several LIN nodes or zones without requiring four separate physical-layer transceivers. The package uses a 0.5 mm terminal pitch and a plastic, dual-inline-compatible, thermally enhanced very-thin quad flat package construction. According to the NXP TJA1124 datasheet, transmit data streams generated by the LIN commander protocol controller are converted into optimized bus signals shaped to minimize electromagnetic emissions. The LIN commander output pins are pulled high through internal termination resistors. Corresponding receivers detect incoming LIN bus data and present it to the host controller on RXD1, RXD2, RXD3, and RXD4. Typical uses include four-channel LIN aggregation in automotive body, comfort, seat, lighting, and door modules; LIN gateways; industrial distributed control systems; and embedded controllers requiring several bus interfaces. A microcontroller can manage wake-up, framing, diagnostics, and higher-level LIN traffic while the TJA1124 handles the physical bus connection and signal shaping. PCB implementation should account for the 0.5 mm terminal pitch, thermal-enhanced package, exposed pad, and high-speed edge behavior. Follow the land pattern, exposed-pad soldering, and decoupling recommendations in the manufacturer datasheet. Confirm bus levels, pull-up requirements, transceiver mode behavior, and EMC margins against the target LIN network before production release. This page organizes the manufacturer documentation, package information, interface alternatives, application guidance, and engineering design notes needed to evaluate the TJA1124BHG/0Z as a four-channel LIN physical-layer interface.
TJA1128BTK/0Z - LIN SBC with 85mA LDO | NXP
The NXP Semiconductors TJA1128BTK/0Z is an automotive LIN mini system basis chip with an integrated LIN transceiver, low-dropout voltage regulator, window watchdog, wake-up inputs, and system-control functions in a 14-HVSON package measuring 3 x 4.5 mm. The regulator can deliver up to 85 mA, while the TJA1128 family provides 3.3 V or 5.0 V output options for powering microcontrollers and peripheral devices. A LIN system basis chip, or SBC, is an automotive interface IC that consolidates a communication transceiver with local power regulation and supervisory functions. The TJA1128 belongs to the broader system basis chip hierarchy, combining a LIN transceiver, LDO linear regulator, watchdog timer, wake-up logic, and high-voltage I/O in one device. This integration reduces the number of separate components required in a LIN slave or compact automotive control node. The TJA1128BTK/0Z integrates two WAKE inputs, one general-purpose input, and one high-voltage multipurpose output alongside its LIN transceiver. Its window watchdog monitors controller execution and can initiate a system recovery when expected activity is absent. The 85 mA regulator capacity supports low-power microcontrollers and associated peripherals, while the very-low-power operating modes help reduce standby consumption in parked vehicles. Automotive system-basis designs require careful separation between battery-backed supply domains, communication interfaces, and low-power wake-up logic. The TJA1128 combines these functions behind a common device-control structure, reducing component count and simplifying software integration. Its 14-HVSON package also requires careful PCB layout and exposed-pad thermal management to maintain reliable operation across automotive temperature conditions. Typical uses include LIN-controlled door modules, seat and window controllers, body-control nodes, climate-control interfaces, sensor hubs, and small actuator controllers. A LIN slave can use the integrated transceiver to communicate with a vehicle network, the LDO to power a local microcontroller, and the wake-up inputs to return from a low-power state without keeping the entire node continuously active. When designing the PCB, place input, output, and decoupling capacitors close to their associated pins, preserve the package land pattern exactly, and provide adequate copper around the exposed pad. Confirm that the selected regulator-output option satisfies the controller voltage, and validate the watchdog and wake-up timing against the vehicle-network sleep and wake strategy. The manufacturer datasheet should govern final pin assignment, decoupling values, and layout constraints. This product page combines the manufacturer's functional description with practical guidance for LIN nodes, regulator selection, watchdog configuration, thermal layout, and same-package alternatives. It helps engineers distinguish the TJA1128 from a standalone LIN transceiver while keeping the design focused on a compact automotive system-basis architecture.
