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. This page synthesizes distributor pricing from DigiKey, Mouser, and LCSC, plus drop-in alternatives and partial-networking design notes that are not consolidated in a single place on the manufacturer datasheet.
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/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.

The transceiver supports CAN communication in vehicles and other networked equipment, while its partial-networking capability allows selected nodes to remain asleep until a relevant bus activity is detected. The available manufacturer datasheet should be used as the authoritative reference for electrical limits, timing, pin functions, wake-up behavior, and application-specific implementation details.
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.
TJA1442AT/0Z - 5 Mbps CAN FD Transceiver | NXP
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.

The manufacturer identifies RoHS compliance, lead-free construction, and RoHS-compliant tape-and-reel presentation. The -40 °C to +150 °C operating range is especially relevant where equipment can be exposed to elevated ambient temperatures inside an enclosure or vehicle cabin. Typical uses include retrofitting an existing TJA1042 or TJA1044GT CAN node, building a 5 Mbps CAN FD gateway, connecting a microcontroller or industrial controller to a CAN bus, and developing automotive diagnostic or distributed control equipment. The manufacturer datasheet states that the TJA1442 offers pin compatibility and is designed to avoid changes to hardware and software design for supported existing applications. The primary design check is the controller-to-transceiver logic interface, CANH and CANL bus connection, supply decoupling, and Standby-state behavior. Because supported replacement applications and pin compatibility are application-specific, engineers should verify the complete NXP datasheet, including electrical limits, bus timing, input thresholds, bus-fault behavior, and external component recommendations, before releasing a new PCB.

It is particularly appropriate when a compact surface-mount transceiver, selectable low-power modes and centralized bus-fault awareness are required. Board layout must preserve the differential CAN_H and CAN_L return path and provide suitable termination and common-mode protection for the target network. For a new design, compare the device against the TJA1443ATK/0Z automotive-grade ordering option and confirmed alternatives such as TCAN1043A. Do not assume electrical or qualification equivalence from package similarity alone; verify supply voltage, mode-control polarity, transceiver delay, bus fault behavior and automotive qualification against the system requirements.

The TJA1448 provides two complete CAN channels, making it useful where a system requires redundant channels, gateway isolation, or simultaneous communication across separate CAN buses. The TJA1448AT/0Z supports Normal, Silent, Sleep, and Standby operating modes according to the product information. Its dual-channel architecture, 5 Mbit/s capability, and 5 V operation make it appropriate for automotive body and chassis electronics, industrial automation equipment, robotics, transport systems, and CAN FD gateways. Standby mode is particularly useful in systems that need to retain low-power behavior while supporting controlled transitions between operating states. The device is identified as an automotive AEC-Q100 part in distributor product information, making it relevant to automotive qualification programs. Its 14-pin SOIC package supports conventional surface-mount assembly and integration into compact controller boards. Because the TJA1448 family is described as pin-compatible with existing dual high-speed CAN and CAN FD transceiver designs, it can be considered during replacement projects after confirming the exact pin functions, operating-mode logic, and bus timing of the incumbent device. For robust implementation, place the transceiver close to the CAN connector and route the CANH and CANL conductors as a differential pair with controlled impedance. Keep the bus stubs short, provide the required termination at both ends of the network, and follow the decoupling and grounding recommendations in the NXP datasheet. Review low-power mode transitions and fault behavior against the system’s wake-up and diagnostic requirements before finalizing the design.

Two integrated channels make it suitable for systems that need two CAN bus connections without using separate single-channel transceivers. Its high-temperature operating range supports industrial, automotive, and communications equipment where the ambient enclosure temperature may substantially exceed conventional commercial limits. Typical uses include automotive body and powertrain electronics, industrial automation equipment, building automation gateways, CAN-based sensors, robotics, and embedded control systems. In a dual-channel installation, each channel connects to a separate CAN FD controller interface and its associated differential bus wiring while sharing the device supply and operating-mode controls. Designers should preserve the datasheet-defined decoupling and bus-termination layout, validate logic compatibility at VIO, and verify that the PCB footprint matches the 14-pin SOIC outline. The standby and wake-up functions should be checked against the controller's power-management strategy so the remote node can enter low-power operation without preventing required bus communication.

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.

It connects a CAN or CAN FD controller to a two-wire automotive CAN bus while implementing CAN SIC according to ISO 11898-2:2024. Its principal advantages are reduced signal ringing, improved bit-timing symmetry, and support for larger bus networks without changing the host hardware or software. A CAN transceiver is the physical-layer interface between a digital bus controller and the differential CAN bus. The TJA1462 belongs to the TJA146x family of CAN and CAN FD transceivers, combining bus-driver, receiver, logic-level I/O, and standby functionality in one IC. The VIO pin permits the logic-side supply voltage to be selected independently from the transceiver supply, while STB provides a low-power control input. The TJA1462 supports reliable CAN FD communication at data rates up to 8 Mbit/s. According to the manufacturer product information, reducing signal ringing and improving bit-timing symmetry enables larger CAN FD networks. CAN SIC also improves compatibility in installations where long stubs, unequal trace lengths, or multiple termination conditions would otherwise distort edge timing. Standby mode provides a practical way to reduce activity when the network is not being used. The device is intended as a retrofit option for existing high-speed Classical CAN and CAN FD designs using compatible NXP transceivers such as the TJA1042 or TJA1044. NXP states that the TJA1462 offers pin compatibility and is designed to avoid hardware and software changes. The TJA1462AT variant uses the SO8 package, while the HVSON8 option is a different package and is therefore not a drop-in substitute. Typical uses include automotive CAN FD gateways, electric-vehicle body controllers, industrial vehicle networks, engine controllers, lighting controllers, and battery-management systems. The 150°C temperature indication associated with the AT automotive ordering variant makes it suitable for applications requiring an extended automotive temperature range, subject to the complete datasheet limits and qualification requirements.

The device operates from a 4.5 V to 5.5 V VCC supply, supports up to 8 Mbit/s in CAN FD networks, and offers a low-power Standby mode entered via the STB pin. The TJA1462 is intended as a pin-compatible drop-in replacement for the TJA1042 or TJA1044 from NXP, enabling direct retrofit without hardware or software changes. The architecture uses a fully differential driver with slope control and integrated bus failure protection, including TXD dominant time-out, bus dominant time-out, and overtemperature shutdown. Receiver symmetry is trimmed to provide reliable operation at recessive voltages as low as 0.5 V on the bus. Typical applications include automotive ECUs, body control modules, gateway ECUs, industrial CAN nodes, and any node that needs to coexist with mixed CAN FD / classical CAN networks on the same bus segment, where the SIC function reduces the required bit time and improves EMC behavior on long stubs. When designing with the TJA1462BT, place a 100 nF decoupling capacitor close to pin 8 (VCC) and ensure the bus termination (typically 120 ohm at each end of the bus) is present. Use the STB pin to enter Standby when the node is inactive to reduce quiescent current, and verify that the bit timing of the CAN controller remains within ISO 11898-2:2024 limits for SIC operation.

TJA1463ATK/0Z - CAN SIC Transceiver, 8Mbit/s, Sleep | NXP
The NXP Semiconductors TJA1463ATK/0Z is a CAN Signal Improvement Capability (SIC) transceiver with Sleep mode, supporting CAN FD communication up to 8 Mbit/s and housed in a 14-pin HVSON (SOT1086-1) package. It implements the SIC behavior defined in CiA 601-4 and ISO 11898-2:2024 parameter set C, while remaining fully interoperable with classical CAN and CAN FD nodes defined by ISO 11898-2:2024 and SAE J2284-1 through J2284-5. The /0Z suffix denotes the tape-and-reel, 100% matte-tin lead-free, Pb-free, AEC-Q100-qualified automotive-grade ordering code. A CAN SIC (CAN Signal Improvement Capability) transceiver is a physical-layer device that sits between a CAN protocol controller and the differential CAN bus, translating the controller's TX/RX logic into the bus's dominant/recessive differential signaling. The "signal improvement" function actively damps the dominant-to-recessive edge ringing that traditionally limits CAN FD bus length and stub density, allowing larger topologies than classical HS-CAN. In the system hierarchy it belongs to: CAN transceiver -> network interface IC -> interface IC -> integrated circuit -> semiconductor. Key features include up to 8 Mbit/s CAN FD data rate, tight bit-timing symmetry enabling communication at 5 Mbit/s with a higher node count, an integrated low-power Sleep mode with remote wake-up via bus activity, a separate VIO supply pin for flexible MCU interfacing from 1.8V to 5V, an STB (standby) mode pin, and an ERR output pin that flags local and global bus failures.

TJF1051T/3/1 - High-Speed CAN Transceiver SOIC-8 | NXP
The NXP TJF1051T/3/1 is a high-speed Controller Area Network (CAN) transceiver that serves as the physical interface between a CAN protocol controller and the differential CAN bus, supplied in an 8-pin SOIC package. It supports CAN data rates up to 1 Mbit/s (classical CAN) and the CAN FD (Flexible Data-rate) extension at higher bus speeds, with versions tailored to common microcontroller I/O voltages. The /3 suffix denotes a 5 V MCU interface variant where VIO is internally tied to VCC, so TXD/RXD logic levels are compatible with 5 V microcontrollers directly. A CAN transceiver is a physical-layer (PHY) device that converts digital logic from a microcontroller into the differential dominant/recessive signaling required by the ISO 11898 CAN bus standard. Inside the broader product taxonomy it sits beneath CAN interface ICs -> network interface ICs -> interface ICs -> integrated circuits. The TJF1051T belongs to NXP's family of third-generation high-speed CAN transceivers designed to replace the legacy TJA1051/PCA82C250/IFX1051LE predecessors while delivering enhanced electromagnetic compatibility and electrostatic discharge immunity. Key features of the TJF1051T/3/1 include improved EMC/ESD performance compared with earlier generations, ideal passive behavior on the CAN bus when supply voltage is removed (zero load with VCC = 0 V so the bus is not biased by the node), an S (Silent) pin for low-power listen-only mode, and bus-fault protection against automotive transients per ISO 7637. The differential bus pins (CANH, CANL) tolerate typical automotive battery and jump-start voltages present on 12 V systems. Internal architecture combines a high-speed differential driver/receiver pair with thermal shutdown, under-voltage detection on VCC/VIO, bus-dominant time-out protection, and an unpowered node detection that keeps the bus in recessive when the IC is off. Together these blocks implement the CAN physical layer defined in ISO 11898-2:2003, ISO 11898-5:2007 and the pending updated ISO 11898-2:2016 release, including the CAN FD frame format. Typical applications include body-control modules, powertrain networks, electric vehicle battery management (BMS) slave nodes, industrial CANopen and DeviceNet nodes, onboard chargers, and CAN-to-UART bridges for diagnostics. The /3 variant is the right choice when pairing with a 5 V microcontroller, while the non-/3 variant supports a separate VIO rail for 3.3 V MCUs. The TJF1051T/3/1 was developed as a pin-compatible, functionally equivalent upgrade for the TJA1051T/3 in existing automotive CAN networks, allowing reuse of proven PCB footprints. When designing, ensure the bus-termination topology and stub lengths follow ISO 11898-2 to maximize signal integrity at 1 Mbit/s and beyond. The Silent pin enables low-current standby and is required for partial-networking sleep modes.

TJF1051T/3/1J - High-Speed CAN Transceiver, SO-8 | NXP
The NXP TJF1051T/3/1J is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and the differential two-wire CAN bus, packaged in an 8-pin SO (SOIC-8) surface-mount package. It supports data rates up to 5 Mbit/s and implements the CAN physical layer defined by ISO 11898-2:2003, ISO 11898-5:2007, and the pending ISO 11898-2:2016 update. A CAN transceiver is the analog front-end that converts the digital TXD/RXD logic levels of a microcontroller into the differential dominant/recessive signalling required on the CAN bus, while also providing ESD protection, bus fault tolerance, and common-mode rejection. The TJF1051T/3 family adds a VIO level-adapter supply pin that allows direct interfacing to microcontrollers with supply voltages from 3V to 5V, simplifying mixed-voltage designs where the MCU runs at 3.3V but the bus nodes may operate at 5V. Key features include an extremely low ElectroMagnetic Emission (EME) due to built-in slope control on the CANH/CANL outputs, a Silent mode (S) input for low-power bus monitoring without disturbing traffic, and high immunity to ElectroMagnetic Interference (EMI) on the bus lines. The device also includes thermal shutdown, bus dominant time-out protection, and an undervoltage detector on VCC and VIO, ensuring robust behaviour on harsh automotive or industrial bus networks. It is the pin-compatible successor to the TJA1051 with improved EMC behaviour and tighter parametric compliance with the ISO 11898-2:2016 specification. Typical applications include automotive body and chassis CAN nodes, industrial CANopen networks, building automation, and any MCU-to-CAN-bus interface requiring 3.3V or 5V logic compatibility with low EME and high EMI immunity. Compared with older TJA1050/TJA1040 designs, the TJF1051T/3 provides substantially reduced electromagnetic emissions, removing the need for external common-mode chokes in many layouts. When designing with this part, place the VIO decoupling capacitor as close as possible to pin 5 and ensure both VCC and VIO are present before TXD transitions are applied. The Silent mode pin must be tied LOW for normal operation or driven by the MCU when bus diagnostics or low-power standby states are required. The /1 JTR suffix indicates 2500-piece reel packaging.
