TJA1057T/1Z - High-Speed CAN Transceiver | NXP SOIC-8
TJA1057T/1Z

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.

TJA1059TK - Dual HS-CAN Transceiver with Standby Mode | NXP
TJA1059TK

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.

TJA1059TKJ - Dual 1Mbps CAN Transceiver | NXP
TJA1059TKJ

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.

The verified feature set includes one transmit driver and one receive driver, operation from 2.5 Mbit/s to 10 Mbit/s, a 4.45 V minimum and 5.25 V maximum supply, and a 14-TSSOP surface-mount package. Distributor information identifies the TTJ ordering code as reel packaged. 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.

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.

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

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. It is designed and qualified for automotive Ethernet applications, includes an exposed-pad thermal land pattern, and is supplied in tape-and-reel packaging. The device also supports sleep and wake-up forwarding according to the OPEN Alliance sleep/wake-up specification. A 100BASE-T1 Ethernet PHY is a physical-layer transceiver that converts digital MAC data into signals suitable for single-pair twisted-pair automotive networks. The TJA1102 belongs to the broader hierarchy of Ethernet PHY transceiver, network interface controller, communications semiconductor, and integrated-circuit product categories. 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.

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.

TJA1145AT/0Z - 5 Mbit/s CAN FD Transceiver | NXP

NXP Semiconductors TJA1145AT/0Z is an automotive high-speed CAN transceiver for partial networking, providing the interface between a CAN protocol controller and a two-wire CAN bus. It supports CAN and CAN FD communication at data rates up to 5 Mbit/s and combines differential transmit and receive capabilities with selective wake-up functionality. The device is intended for in-vehicle networks where low standby consumption, bus fault tolerance, and partial-networking capability can reduce the energy required by modules that do not communicate continuously. A CAN transceiver is an interface IC within the broader network-communications semiconductor hierarchy. It converts logic-level signals from a CAN controller into differential bus levels and converts differential bus activity back into controller-compatible receive signals. The TJA1145A family adds partial networking, allowing a node to wake selectively when recognized traffic appears on the bus rather than remaining fully active for every unrelated frame. The key features of the TJA1145AT/0Z include support for CAN FD communication up to 5 Mbit/s, differential CAN bus transmission and reception, selective wake-up, and very low power consumption in Standby and Sleep modes. NXP identifies the device as suitable for automotive applications. The device is supplied under the automotive-oriented TJA1145A family designation and is available in a compact surface-mount package, although the exact package dimensions and pin assignments must be confirmed in the manufacturer datasheet before PCB release. The transceiver provides a physical-layer interface for systems that already contain a CAN protocol controller. It does not replace the controller, arbitration logic, or application software. Designers should therefore verify that the selected CAN controller supports the required classical CAN or CAN FD data rates and that its logic levels, supply voltage, and transceiver-control signals match the TJA1145AT/0Z interface. Typical uses include body-control modules, gateway controllers, telematics units, battery-management systems, and other ECUs connected to partially dormant vehicle networks. Partial networking is especially useful where many nodes share a CAN backbone but only a subset must communicate at a given time, allowing unneeded modules to remain in a low-power state. PCB implementation requires correct termination, common-mode behavior, and decoupling. The CANH and CANL bus connections should follow the layout guidance in the manufacturer datasheet, while the device supply pins require local high-frequency bypass capacitors. Bus stubs should be minimized, and the 120-ohm termination network belongs at the physical ends of the bus rather than at every node. This page organizes the TJA1145AT/0Z technical profile, verified manufacturer and distributor resources, supported applications, and design guidance. It also distinguishes the exact ordered part number from related TJA1145A variants so engineers can assess protocol behavior, package, and qualification requirements before substituting an alternative.

TJA1145AT/FD/0Z - High-Speed CAN FD Transceiver | NXP | 14-SO

TJA1145AT-FD-0Z is an NXP high-speed CAN/CAN FD transceiver designed for automotive applications, supporting data rates up to 5 Mbit/s in the CAN FD fast phase and packaged in a 14-pin SO (SOIC-14) outline. It provides a 1/1 half-duplex CANbus interface between a microcontroller with a CAN protocol controller and the physical bus, while also incorporating FD-passive partial-networking capability that allows the node to ignore CAN FD frames while waiting for a valid wake-up frame in Sleep or Standby mode. A CAN/CAN FD transceiver is a bus interface IC belonging to the broader category of automotive network transceivers, which itself falls under interface ICs and then integrated circuits in the component taxonomy. These devices sit between a low-voltage digital microcontroller and the differential CAN bus, providing the physical-layer translation that lets a 3.5-bit logic signal coexist with multi-node bus topology. Modern CAN FD transceivers extend classic CAN with flexible data-rate support, enabling payload sizes up to 64 bytes and baud rates above 1 Mbit/s. Key features of the TJA1145AT/FD/0Z include a 4.5 V to 5.5 V supply range, low-power Sleep and Standby modes with local and bus wake-up, integrated ±8 kV HBM ESD protection on bus pins (per NXP datasheet), and automotive-grade qualification with an operating junction temperature up to +150 °C. The 'FD' suffix variant adds the FD-passive partial-networking function that distinguishes it from the non-FD TJA1145AT/0Z. Architecturally, the device uses a differential transmitter with slope control for low-EMI operation, a high-impedance differential receiver, and an SPI control interface for mode and configuration management. The half-duplex 1/1 configuration simplifies CAN bus timing by following two cables, and the SOIC-14 footprint allows drop-in compatibility with classic 14-pin CAN transceivers. Typical applications include automotive body and powertrain ECUs, gateway modules, partial-networking nodes in CAN FD bus systems, industrial CAN FD bridges, and diagnostic interfaces supporting UDS and OBD-II. For automotive designs requiring the same part in a 12-pin HVSON package, the TJA1145ATK/FD/0Z offers equivalent functionality in a smaller footprint. When designing with this transceiver, keep the bus termination (typically 120 Ω at each end of the bus) external and place a 100 nF decoupling capacitor close to the VCC pin. Pay attention to the VIO supply if the host MCU runs at 3.3 V, and verify wake-up timing against the network manager's bus-sleep requirements.

TJA1145T/FDJ - 2 Mbit/s CAN FD Transceiver | NXP

The NXP TJA1145T/FDJ is a high-speed CAN transceiver for partial networking, with data rates guaranteed up to 2 Mbit/s in a 14-lead SO14 small-outline plastic package measuring 8.65 mm by 3.9 mm by 1.75 mm. It supports autonomous bus biasing according to ISO 11898-6:2013 and provides dedicated FD-passive behavior in the TJA1145/FD variants. A CAN transceiver is a physical-layer interface IC that connects a host controller or microcontroller to a Controller Area Network bus. The TJA1145 combines the CAN physical-layer transceiver with partial-networking functionality, allowing a node to remain selectively awake while other portions of a vehicle network are inactive. In this product hierarchy, it is a CAN interface IC, bus transceiver, network interface, and power-management-aware communication component. The device is fully compliant with ISO 11898-2:2003, ISO 11898-5:2007, and ISO 11898-6:2013. Its timing is guaranteed for CAN communication rates up to 2 Mbit/s. The FD-passive implementation is designed to ignore CAN FD frames while the device waits for a valid wake-up frame in Sleep or Standby mode, reducing unnecessary wake-up activity while preserving selective network communication. The TJA1145 family is optimized for in-vehicle high-speed networking. Partial networking reduces the electrical burden associated with waking every node on a CAN bus, which is particularly valuable in distributed automotive systems containing multiple control modules, body-comfort systems, and diagnostic equipment. Its autonomous bus-biasing feature supports bus management according to ISO 11898-6:2013. Typical uses include vehicle CAN gateways, body-control modules, infotainment interfaces, electronic control units, comfort systems, and gateway nodes that must wake selectively from a partially sleeping network. The TJA1145T/FDJ is especially relevant where a design needs CAN FD-aware wake behavior, high-speed operation, and the established SO14 footprint associated with the TJA1145T family. Designers should verify the exact pin configuration, operating voltage, transceiver-mode behavior, external component requirements, and PCB land pattern against the NXP TJA1145 datasheet before release. The verified lifecycle information indicates that TJA1145T is at End of Life, so procurement planning and migration assessment are important for long-running automotive programs. This page combines verified manufacturer specifications, distributor availability, lifecycle information, same-footprint migration evidence, and practical engineering guidance. It distinguishes documented electrical facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers evaluate the TJA1145T/FDJ without relying on assumptions.

TJA1145T

TJA1145T/FDJ - High-Speed CAN FD Transceiver w/ Partial Networking

The NXP TJA1145T/FDJ is a high-speed CAN (Controller Area Network) transceiver with CAN FD (Flexible Data rate) support and dedicated partial networking capability, housed in a 14-pin SO package. The device operates from a 4.5V to 5.5V supply on VCC and is fully compliant with ISO 11898-2:2003, ISO 11898-5:2007, and ISO 11898-6:2013 standards. Per the NXP product page, the TJA1145T variant supports data rates up to 2 Mbit/s. A CAN transceiver is a physical-layer interface that connects a CAN protocol controller to the differential CAN bus, providing differential transmit/receive signaling, bus fault protection, and electromagnetic immunity. The TJA1145T belongs to the NXP TJA1145 family, which integrates ISO 11898-6 selective wake-up logic ('partial networking') so an ECU can ignore CAN traffic while monitoring the bus for a designated wake-up frame, dramatically reducing quiescent current in always-connected body-electronics ECUs. Key features include autonomous bus biasing per ISO 11898-6:2013, an FD-passive mode that ignores CAN FD frames during Sleep/Standby to avoid false wake-ups, low-power Sleep and Standby modes, and an INH (inhibit) output for controlling an external voltage regulator. The 14-SO package provides a small footprint suitable for body-control, gateway, and cluster modules. The TJA1145T/FDJ uses an ISO 11898-6 selective-wake architecture that combines a low-power wake receiver with the high-speed CAN data path. When the host microcontroller commands Sleep mode, the data path shuts down while the wake receiver remains active; only a matching CAN-ID frame wakes the ECU, allowing significant quiescent-current savings versus traditional always-on transceivers. Typical applications include automotive body-control modules (BCM), gateway ECUs, instrument clusters, and ADAS sensor nodes where selective wake-up minimizes parasitic battery drain. The 'T' suffix identifies this specific variant within the TJA1145 family (distinct from TJA1145 and TJA1145A), and the '/FD' suffix denotes CAN FD passive support. When designing with this part, ensure the bus termination (typically 120 ohm at each end of the CAN bus segment) is correctly applied and that the INH pin is used to control an external LDO if low quiescent current is required. Note that TJA1145T is approaching end-of-life; verify current lifecycle status with NXP before committing to new designs. This page synthesizes NXP datasheet excerpts, distributor pricing and stock, drop-in variants from the same TJA1145 family, and practical design notes not consolidated in the manufacturer datasheet alone.

TJA1441AT/0Z

TJA1441AT/0Z - 5 Mbit/s CAN FD Transceiver, SOIC-8 | NXP

The NXP Semiconductors TJA1441AT/0Z is a 5 Mbit/s high-speed CAN transceiver with integrated Silent mode, supplied in an 8-pin SOIC (SO-8) surface-mount package. It provides one CAN TXD and one RXD logic interface, a VIO pin for 3.3 V and 5 V microcontroller compatibility, and a standard ISO 11898-2 compliant CAN bus driver and receiver stage. A CAN transceiver is the physical-layer interface between a host controller and the CAN bus wiring. It converts logic-level TXD into differential CANH and CANL bus signals, and converts received differential bus levels back into a logic-level RXD signal. In the equipment hierarchy the TJA1441AT/0Z sits between the CAN controller (microcontroller or dedicated CAN controller) and the transceiver, part of the CAN controller > CAN transceiver > physical-layer interface > interface IC chain. Key features include a data rate of up to 5 Mbit/s, a Silent mode that puts the transmitter into a recessive, high-impedance state while the receiver stays active, a VIO supply pin that allows the logic side to run from 1.8 V up to 5.5 V, and low quiescent current for reduced system power. The device also features bus fault and short-circuit protection on the CANL and CANH pins, plus thermal shutdown and an extended operating temperature range suitable for industrial equipment. Internally the transceiver combines a CMOS-compatible logic input stage, a differential line driver with a wide common-mode range, and a complementary differential receiver with hysteresis for noise immunity. Because the Silent mode holds the driver in recessive state, a node can stay connected to an active bus without contributing error frames, which is useful in partially powered or listen-only nodes and in test and diagnostic setups. The VIO pin independently powers the digital interface, so the TXD and RXD pins remain compatible with 3.3 V and 5 V microcontrollers while the transceiver core runs from the standard 5 V rail. Typical applications include automotive and industrial body control modules, gateway and aggregator units, electric vehicle powertrain controllers, instrumentation clusters, sensor hub nodes, and factory automation equipment where a CAN bus backbone links remote nodes over long cable runs. When designing with the TJA1441AT/0Z, terminate the bus with 120 ohm resistors at both ends only, keep the CANH and CANL traces as a tightly coupled differential pair, and follow the layout guidance in the NXP TJA1441 data sheet. The VIO decoupling capacitor should be placed directly on the VIO pin for clean logic levels. This page brings together the manufacturer data sheet information, pin-level detail, cross-reference drop-in alternatives, and practical layout and application guidance so engineers can qualify the TJA1441AT/0Z quickly and design a compliant CAN node around it.

TJA1441BT/0Z - 5 Mbps CAN FD Transceiver | NXP | SOIC-8

The NXP Semiconductors TJA1441BT/0Z is a high-speed CAN FD transceiver with Silent mode, designed to interface a CAN or CAN FD protocol controller with a two-wire CAN bus. It supports CAN FD communication at data rates up to 5 Mbit/s and is supplied in an 8-pin SOIC package. The device is intended as a simple replacement for high-speed Classical CAN and CAN FD transceivers such as the NXP TJA1051 and TJA1057, helping existing designs retain their hardware and software structure. A CAN transceiver is an interface IC that converts logic-level transmit and receive signals into a differential CAN bus and presents the bus state to a controller. The TJA1441 family belongs to the broader CAN interface, transceiver, and industrial communication hierarchy. Its 5 V operation, 5 Mbit/s data-rate capability, 3 mA quiescent current, and normal or Silent operating modes make it appropriate for distributed embedded systems that need reliable communication over a two-wire differential bus. The TJA1441BT/0Z includes ESD protection, undervoltage protection, thermal shutdown protection, and a TXD dominant timeout function. These protections support robust operation in automotive, industrial, and embedded CAN networks where cable transients and supply disturbances are common. The 150°C maximum operating temperature shown in the product listing supports use across demanding temperature ranges, while AEC-Q100 qualification is identified in the product description for automotive-oriented designs. Typical uses include automotive body electronics, industrial automation equipment, robotics controllers, building automation gateways, and CAN-connected sensors. The 8-pin SOIC-8 package is straightforward to assemble on conventional PCB technology and can replace compatible existing CAN transceivers without changing the controller or bus software. For a new design, confirm the exact pin description, recommended external components, bus termination, and transceiver mode timing in the NXP TJA1441 datasheet. The most important design trade-off is that this is a CAN physical-layer transceiver, not a standalone CAN controller. The host MCU or other protocol controller must generate TXD and receive RXD, while the PCB must provide correct CANH and CANL routing, termination at appropriate bus locations, adequate grounding, and protection for the application environment. The component should not be selected solely by its listed data rate; verify supply voltage, I/O voltage compatibility, mode-control logic, and bus fault requirements against the complete device specification.

TJA1441BTK/0Z - 5 Mbit/s CAN FD Transceiver | NXP

NXP Semiconductors TJA1441BTK/0Z is a high-speed CAN transceiver with Silent mode for CAN and CAN FD networks, supporting data rates up to 5 Mbit/s in an 8-HVSON surface-mount package. It provides the physical-layer interface between a CAN or CAN FD protocol controller and a two-wire CAN bus, combining a transmitter, receiver, bus-driver protection, and Silent-mode control. A CAN transceiver is an interface integrated circuit that converts logic-level signals from a CAN controller into differential bus signals and converts received differential bus levels back into controller-compatible logic. In the broader hierarchy, a CAN transceiver is a bus interface IC, a communications interface device, and a semiconductor. It supports the physical layer of Controller Area Network communication while the CAN controller handles frame construction, arbitration, error management, and higher-level protocols. The TJA1441 family combines support for Classical CAN and CAN FD operation with a maximum CAN FD fast-phase data rate of 5 Mbit/s. Its Silent mode provides a way to place the transceiver into a state suitable for designs that require a disabled or low-impact CAN interface. The manufacturer also describes the TJA1441 as a potential simple replacement for established high-speed Classical CAN and CAN FD transceivers, helping simplify upgrades without changing the surrounding hardware or software architecture. Technical design work centers on correct implementation of the CAN bus, termination, decoupling, and protection. Because the device interfaces to a two-wire differential network, both transmitters connected to the same bus must be able to dominate recessive bus states without destructive contention. PCB signal integrity is therefore important from the controller through the transceiver to the connector, particularly in industrial, automotive, and communication systems operating at longer cable lengths or higher data rates. Typical uses include CAN FD gateways, industrial automation equipment, automotive body and comfort electronics, building-control systems, robotics, diagnostic equipment, and embedded control platforms. The 5 Mbit/s capability is useful when a CAN FD controller uses the faster data phase, while compatibility with Classical CAN supports mixed-speed network segments and incremental migration from conventional CAN systems. When assigning PCB resources, use the manufacturer pin and package information for the exact ordering code, and place local input and output capacitors close to their associated pins. Keep the CANH and CANL routing compact and symmetrical, provide the specified common-mode choke and bus protection where required, and install the bus termination at the physical ends of the network rather than beside the transceiver. This product page combines manufacturer interface and package information, verified source links, drop-in candidate details, comparison parameters, and practical CAN-bus design guidance. It also distinguishes verified replacements from alternatives that require footprint, logic, or firmware validation before use.

The NXP Semiconductors TJA1442AT/0Z is a high-speed CAN and CAN FD interface transceiver with one transmitter and one receiver, a maximum documented data rate of 5 Mbps, and a 4.5 V to 5.5 V supply range. The device is supplied in an 8-pin SOIC package for surface-mount PCB assembly and includes a standby mode for controlled low-power operation. Its operating-temperature specification extends from -40°C to +150°C junction temperature. A CAN transceiver is an interface IC that connects a CAN controller or host processor to a physical two-wire CAN bus. It converts logic-level TXD and RXD signals into bus-compatible CAN signals and presents the received bus state to the controller. As a CAN FD-capable physical-layer device, the TJA1442AT/0Z supports communication networks whose controllers use the CAN FD protocol while remaining associated with the broader Controller Area Network ecosystem. The TJA1442AT/0Z provides a 5 Mbps maximum data rate, a half-duplex 1-transmitter, 1-receiver configuration, and 50 mV receiver hysteresis. The specified 4.5 V to 5.5 V supply range permits operation from regulated 5 V rails. Receiver hysteresis helps distinguish signaling states around the bus decision threshold, while standby mode provides a mechanism for reducing activity when the node does not need normal bus communication. The 8-SOIC package supports conventional surface-mount assembly and provides separate pins for the CAN bus, ground, supply, mode control, and controller-interface signals. The listed package dimensions correspond to an 8-pin SOIC with a 3.90 mm body width. The manufacturer describes the TJA144x family as compatible with existing high-speed classical CAN and CAN FD transceiver hardware, allowing retrofit without changing the established PCB footprint or associated software approach. Typical uses include distributed industrial control, automotive electronic modules, building automation, robotics, and other embedded networks in which a host controller communicates over a two-wire CAN bus. The 5 Mbps capability is relevant to CAN FD nodes with greater payload throughput than classical CAN, while the half-duplex interface supports a shared bus architecture. Designers should still verify timing, termination, bus topology, and controller compatibility in the final system. For PCB design, place the transceiver close to the CAN connector and bus routing, maintain a continuous ground path, and follow the manufacturer's application guidance for connector stubs and protection. The 4.5 V minimum supply requirement excludes direct operation below that voltage, so the device should be supplied from a regulated 5 V rail. Standby and mode-control behavior must also be checked against the host firmware power states. This product record combines NXP manufacturer information, distributor package and lifecycle data, the official datasheet, and verified cross-reference results. It also separates documented electrical facts from unknown commercial details, making the page useful for initial design selection while clearly identifying where engineering verification or supplier confirmation is still required.

TJA144x - Dual CAN FD Transceiver Family | NXP Semiconductors

The NXP TJA144x is a family of dual high-speed CAN/CAN FD transceiver ICs that provide an interface between a Controller Area Network (CAN) or CAN FD protocol controller and the physical two-wire CAN bus, supporting data rates up to 5 Mbit/s and compliant with ISO 11898-2, SAE J2284 and AEC-Q100 Grade 0. The family is offered in HVSON-14 (3.6x2.0 mm) and HVSON-8 packages, with variants including Basic, Standby, Dual Standby, and Sleep power modes for different power-management strategies in automotive networks. The TJA144x operates from a 4.5V to 40V supply (load-dump tolerant), tolerates -5V to +45V on the bus pins, and integrates dominant-timeout, thermal shutdown, and bus-pin short-circuit protection. A CAN FD transceiver (also called CAN Flexible Data-rate transceiver) is a physical-layer device that converts digital transmit/receive data from a CAN protocol controller into differential voltage levels on the CANH/CANL bus wires. As the boundary between the protocol controller and the bus medium, it provides dominant/recessive arbitration, common-mode rejection, and EMC robustness required in automotive environments. Within the in-vehicle network hierarchy, the CAN transceiver sits below the microcontroller (MCU) and above the wiring harness, forming the physical layer of the OSI seven-layer reference model for CAN. Key features of the TJA144x family include an ultra-low-current Standby mode with remote CAN wake-up detection, very low electromagnetic emission (EME) and high electromagnetic immunity (EMI), excellent ESD protection (±8 kV HBM on bus pins), and pin compatibility with the prior TJA1042/1051 generations for easy retrofit. The HVSON-14 package exposes an exposed thermal pad for low thermal resistance, and the HVSON-8 variant offers a compact footprint for ECU miniaturization. Devices are AEC-Q100 Grade 0 qualified for automotive temperatures from -40 °C to +150 °C. Typical applications include body control modules (BCM), gateway ECUs, ADAS sensor nodes, instrument cluster CAN backbones, electric-vehicle battery-management communication, and any in-vehicle network that requires migration from classical CAN to CAN FD without redesigning the PCB or firmware. The 5 Mbit/s CAN FD capability is essential for high-bandwidth automotive Ethernet-cascade gateways and radar/LiDAR sensor clusters. When designing with the TJA144x, ensure the VCC supply is decoupled with a 100 nF ceramic capacitor close to pin VCC, and that the bus terminations (typically 120 Ω) are present at each end of the CAN bus segment. The VIO pin on HVSON-14 variants allows level-shifting between the 3.3V or 5V MCU and the 5V transceiver logic domain. This page synthesizes distributor pricing, drop-in alternatives within the TJA144x family and from competitor manufacturers, and practical design notes not consolidated on the manufacturer datasheet, giving design engineers a single decision-ready reference for CAN FD physical-layer selection.
