TJA1049T - 3V to 5V High-Speed CAN Transceiver | NXP
The NXP Semiconductors TJA1049T is a high-speed CAN transceiver with 3 V to 5 V microcontroller interfacing, implemented in an 8-pin SOIC package. It provides the physical-layer interface between a CAN protocol controller and a two-wire CAN bus while supporting the ISO 11898 standards identified in the manufacturer documentation. The device is intended for automotive and industrial networking systems that require reliable bidirectional CAN communication. A CAN transceiver is an interface IC within the broader CAN controller, CAN physical layer, network interface, and semiconductor hierarchy. It converts logic-level TXD and RXD signals into the dominant and recessive states carried by CANH and CANL. Conversely, it converts bus activity back into a logic-level receive signal, allowing a microcontroller or dedicated CAN controller to exchange protocol data with other nodes. Key verified features include direct interfacing with microcontrollers operating from 3 V to 5 V, support for the ISO 11898-2:2003 and ISO 11898-5:2007 standards, and compatibility with existing TJA1040, PCA82C250, and PCA82C251 applications when operated with a 5 V microcontroller. The NXP TJA1049T/3 and TJA1049TK/3 variants also support low-voltage microcontroller interfaces. The TJA1049 uses a physical-layer architecture designed for high-speed Controller Area Network communication. Its eight-pin SOIC arrangement provides separate transmit, receive, standby-control, supply, and bus connections, allowing a straightforward interface to a CAN controller. Because the supplied evidence does not include complete timing, current, loop-delay, or temperature limits, those values remain unspecified rather than being inferred. Typical uses include in-vehicle Controller Area Network nodes, industrial automation equipment, robotics controllers, building-automation gateways, and embedded industrial communication modules. The 3 V interface capability is especially useful when the associated microcontroller operates below the traditional 5 V CAN-transceiver supply level. The standby function supports systems where local bus participation must be disabled to reduce activity or control system state. Designers should use the exact datasheet pin configuration and verify the MCU, transceiver, bus, termination, and decoupling connections before layout release. The CAN bus requires suitable 120-ohm termination only where dictated by the network topology, while common-mode and ESD protection requirements depend on the vehicle or industrial environment. Wake-up behavior must also be checked when the original design depends on a particular dominant-to-recessive bus sequence. This page combines the verified manufacturer statements, distributor availability information, pricing evidence, packaging details, and the identified TI cross-reference discussion. It explicitly separates documented facts from unavailable parameters and provides an engineering-focused selection guide for designers evaluating the TJA1049T and its verified drop-in alternative.
TJA1049T/1Z - High-Speed CAN Transceiver with Standby | NXP
The NXP TJA1049T/1Z is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and the two-wire CAN bus, housed in an 8-pin SOIC package. The TJA1049T variant is specified for 5V microcontroller supply rails, supports data rates up to 1 Mbit/s, and includes a low-current Standby mode with remote bus wake-up capability. The device implements the ISO 11898-2:2003 and ISO 11898-5:2007 physical layer standards and is qualified for the pending updated ISO 11898-2:2016 release. A CAN transceiver is a physical-layer interface IC that translates the digital transmit/receive signals of a CAN protocol controller into the differential voltage levels (CANH/CANL) defined by ISO 11898-2 on the bus, while also providing bus-side ESD protection and dominant/recessive arbitration. As an interface IC the TJA1049T/1Z sits between application-layer MCU/processor and the physical CAN bus, making it a foundational building block for in-vehicle networking, industrial automation and any system requiring robust differential serial communication. Key features include a very low quiescent current in Standby mode for battery-powered nodes, a SPLIT output for stabilizing the recessive common-mode voltage in networks with multiple unpowered nodes, and transmit data (TXD) dominant time-out protection that prevents the bus from being permanently clamped if the controller fails. The integrated bus wake-up filter rejects transients on CANH/CANL to ensure false wake-ups do not discharge the battery in automotive quiescent scenarios. Typical applications include automotive body and chassis ECUs, CAN-based powertrain nodes, industrial CANopen and DeviceNet modules, and any 5V microcontroller host that requires a compact, low-power standby-enabled physical-layer interface. Designers often pair the TJA1049T/1Z with 5V MCUs such as the NXP S12K or ST STM32 families, plus a 5V LDO and common-mode choke for EMI hardening. When designing with this part, observe the bus termination: 120 ohm resistors at each network end with optional split termination for better EMC performance. Decouple VCC with 100 nF ceramic close to the pin and provide a robust PCB ground return for the bus ESD clamps to operate as specified.
TJA1049T/3J - 3-5V High-Speed CAN Transceiver | NXP
The NXP TJA1049T/3J is a high-speed CAN transceiver with integrated standby mode for connecting a CAN protocol controller to a physical two-wire CAN bus. It supports direct interfacing with microcontrollers operating from 3 V to 5 V and implements CAN physical-layer requirements identified by NXP with ISO 11898-2:2003, ISO 11898-5:2007, and the pending updated ISO 11898-2:2016 version. The device is supplied in an 8-pin SOIC package. A CAN transceiver is an interface IC that bridges a host controller and a differential communication bus. The CAN controller generates and interprets CAN frames, while the transceiver converts those digital signals into robust differential bus levels and converts received bus levels back into logic-compatible signals. In the hierarchy of electronic components, the TJA1049T/3J belongs to the CAN interface and physical-layer transceiver class, within interface ICs and networking semiconductors. The principal verified features include a 3 V to 5 V microcontroller-interface range, high-speed CAN operation, differential transmit and receive capability, standby support, and compatibility with the CAN physical layer standards listed by NXP. Its standby function is intended for systems that need low-current operation while retaining bus wake-up capability. The physical two-wire interface supports integration into automotive and industrial CAN networks while leaving arbitration, framing, error management, and message scheduling to the CAN controller. Technical use requires a CAN controller with TXD and RXD signal connections, a suitable transceiver supply, CAN bus termination, common-mode support, and correctly configured logic levels. The standby pin and mode timing should be reviewed against the system power-management strategy because entering or leaving standby can affect node availability. Because the verified excerpt does not provide a complete timing table, absolute transceiver delay, loop-delay, propagation-delay, receiver threshold, bus-fault, and current-limit values are left as data-needed fields rather than inferred. Typical applications include automotive body and powertrain electronics, industrial automation equipment, transport systems, embedded gateways, motor controllers, sensor networks, and CAN-based diagnostic equipment. The 8-pin SOIC package is useful when a through-hole-compatible surface-mount assembly process and a compact two-wire bus interface are required. For robust PCB implementation, place the transceiver close to the connector and CAN bus routing, provide solid ground-plane continuity, route CANH and CANL as a tight differential pair, and place termination only at the physical ends of the bus. Verify that the selected CAN controller, supply voltage, transceiver mode pins, and termination strategy match the complete manufacturer datasheet before production release. This page consolidates verified NXP product information, distributor references, package details, interface standards, application context, and design guidance. Missing electrical timing, current, environmental, and absolute maximum values are explicitly marked where the supplied verified data does not support a trustworthy value.
TJA1049TKJ - 5 Mbps CAN Transceiver, 8-HVSON | NXP
The NXP Semiconductors TJA1049TKJ is a 5 Mbps high-speed CAN transceiver with a 4.75 V to 5.25 V supply range, one transmitter, and one receiver in an 8-pin HVSON surface-mount package measuring 3 mm by 3 mm. It interfaces a Controller Area Network protocol controller with a physical two-wire CAN bus and includes standby support for low-power operation. According to the NXP datasheet, the device is designed for automotive high-speed CAN applications. A CAN transceiver is an interface IC that converts logic-level controller signals into differential bus voltages and converts received differential bus levels into logic-compatible receive signals. In the system hierarchy, the TJA1049TKJ belongs to the CAN physical-layer transceiver class, connecting a CAN controller or microcontroller to the CANbus network while providing differential transmit and receive capability. The verified specifications identify a 1/1 driver and receiver arrangement, half duplex operation, 5 Mbps maximum data rate, and 300 mV receiver hysteresis. Its 4.75 V to 5.25 V operating supply range supports regulated 5 V automotive and embedded CAN systems. The standby function can reduce activity when the node is not required to communicate, while the small 8-HVSON package supports compact automotive electronics designs. The TJA1049TKJ is positioned for in-vehicle networks, diagnostic interfaces, body electronics, gateway modules, and industrial or embedded systems using high-speed CAN. It is suitable where a controller requires a physical-layer transceiver rather than a complete CAN controller. System designers must still provide appropriate bus termination, common-mode protection, decoupling, and PCB routing for the installed network topology. The package and pin configuration require careful attention to exposed-pad soldering and thermal behavior. Because the verified source data does not provide a detailed pin-by-pin public pinout, the pinout field is marked unavailable rather than reconstructed from memory. Application selection should also confirm the exact NXP ordering variant, package, and exposed-pad land pattern before PCB release. This page combines the verified manufacturer and distributor references with package-level engineering guidance, comparison fields, and application context for engineers evaluating the TJA1049TKJ. It distinguishes verified specifications from parameters that require confirmation from the complete manufacturer datasheet before layout or qualification decisions.
TJA1050 - High-Speed CAN Transceiver, 5V | NXP Semiconductors
The NXP TJA1050 is a high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and the physical CAN bus, supporting data rates up to 1 Mbit/s in a standard 8-pin SO (SOIC-8) package. Designed for 5V supply operation, the TJA1050 delivers excellent electromagnetic compatibility (EMC) performance and very low power consumption, making it well-suited for both industrial and automotive applications. A CAN transceiver is an interface IC that sits between a microcontroller's CAN protocol controller and the differential CANH/CANL bus wires. Its hierarchical role is: CAN transceiver → bus interface IC → interface integrated circuit → semiconductor. The TJA1050 family forms part of NXP's third-generation high-speed CAN transceivers, succeeding earlier devices like the PCA82C250 with improved slope control, lower electromagnetic emissions, and integrated protection features against bus shorts and transient voltages. Key features include an operating supply voltage range of 4.75V to 5.25V, low quiescent current consumption, integrated thermal protection, and a recessive bus output voltage that approximates the supply voltage (VCC) for improved logic-level compatibility. The device supports both normal and silent (standby-like) modes selected via the S pin and provides differential transmit/receive capability across an extended common-mode range on the bus. Differential receiver thresholds are tightly controlled to support CAN-FD-ready bit timing in many classic CAN networks. The architecture uses a current-driven recessive output and a dominant-driving topology with slope control to minimize ringing and RF emissions. An internal watchdog and thermal shutdown safeguard the die against bus shorts to battery or ground, while an undervoltage detection circuit disables the transmitter when VCC drops below the operational threshold to prevent erroneous bus states during power-up or power-down sequences. Typical applications include automotive body control modules, industrial CAN-based sensor networks, building automation gateways, and battery management systems where galvanic isolation can be implemented with a transformer or capacitive barrier after the transceiver stage. The TJA1050 is commonly paired with 8-bit or 32-bit microcontrollers that include an integrated CAN controller, such as NXP's LPC and S32K families. When designing with the TJA1050, place a 120 Ω termination resistor at each end of the CAN bus segment and keep the stub length under roughly 30 cm at 1 Mbit/s. Decouple VCC with a 100 nF ceramic capacitor close to the supply pin, and provide adequate ground plane coverage under the bus traces to maintain the differential impedance target of 120 Ω. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
TJA1050T/CM - 1Mbit/s CAN Transceiver | NXP | SOIC-8
The NXP Semiconductors TJA1050T/CM is a 1/1 high-speed CAN transceiver with a 4.75 V to 5.25 V supply range, data rates up to 1 Mbit/s, and an 8-pin SOIC package. It provides the physical-layer interface between a CAN protocol controller and a two-wire differential CAN bus. The device supports differential transmission and reception for automotive and industrial networks. A CAN transceiver is an interface IC that converts logic-level controller signals into differential bus signals and converts received bus levels back into digital receive data. In system terms, the TJA1050T/CM belongs to the CAN physical-layer transceiver class, interface IC category, and broader semiconductor hierarchy. Its differential signaling supports noise-resistant communication over long cables and through electrically noisy environments. The verified device data identifies ISO 11898 compatibility, operation up to 1 Mbaud, low electromagnetic emission, a differential receiver with a wide common-mode range, and high electromagnetic immunity. An unpowered node does not disturb the bus lines, while bus-pin protection helps improve robustness. The TXD dominant timeout prevents a permanently dominant transmitter state if TXD is held low by a controller or system failure. The TJA1050T/CM is suitable for CAN-based automotive electronics, industrial control systems, embedded equipment, and communications infrastructure. The NXP product page describes its use between a CAN protocol controller and a two-wire CAN bus. Its 5 V supply requirement makes controller-interface compatibility especially relevant for legacy systems designed around 5 V logic. PCB implementation requires careful termination and bus routing. CAN-H and CAN-L should be treated as a differential pair, with a 120 ohm termination installed at each end of the main bus. The supply should be decoupled close to the device, and the transceiver should be positioned to minimize exposed high-current bus traces. The product page marks the TJA1050 as end of life, so engineers should treat availability and lifecycle migration as important design constraints. The TJA1050T/CM is therefore most appropriate for maintaining or repairing existing 5 V CAN designs, while new designs should confirm the NXP migration path and validate pin, electrical, and protocol compatibility before release. This page combines manufacturer lifecycle information, distributor product identifiers, verified CAN features, and practical interface guidance for engineers evaluating TJA1050T/CM procurement, replacement, PCB reuse, and legacy-system support.
TJA1051AT/0Z - 5Mbps CAN Transceiver | NXP | Automotive
NXP TJA1051AT/0Z is a 5 Mb/s high-speed CAN transceiver with one CAN transmitter and one CAN receiver, supplied in an 8-pin SOIC package. It operates from a 5 V supply and provides Normal and Silent operating modes for automotive and industrial Controller Area Network systems. The device is identified as an AEC-Q100 automotive-grade part in the supplied distributor data. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals between a host controller and the physical CANH and CANL bus conductors. Within the product hierarchy, the TJA1051 belongs to CAN interface ICs, communication interface ICs, and broader semiconductor categories. Its primary function is to provide the physical-layer signaling and bus-driver capability required by a CAN controller. The verified data identifies a maximum signaling rate of 5 Mb/s, one driver, one receiver, a 5 V supply, Normal/Silent mode support, SMD mounting, and an SOIC-8 package. These characteristics suit conventional high-speed CAN networks operating at bit rates up to 5 Mb/s. The small surface-mount package supports compact automotive electronics, industrial controllers, vehicle networking modules, and embedded CAN gateways. Compared with a plain CAN transceiver, the TJA1051 family offers selectable operating behavior through Normal and Silent modes. Normal mode provides the normal CAN communication function, while Silent mode is intended for passive bus monitoring without active bus domination. Engineers must still verify the exact mode-control implementation and pin behavior against the manufacturer datasheet before changing an existing PCB. The 8-pin SOIC package permits reflow assembly and automated inspection, but its exposed lead geometry requires careful solder bridging control. CAN bus nodes should use a symmetric connection to CANH and CANL, a common-mode choke where required, and a termination network matched to the network topology. The transceiver itself does not replace termination resistors, common-mode filtering, or protection components. This product page combines the verified NXP description and distributor listings with practical selection guidance, comparison information, and design notes. Pricing shown is the verified LCSC starting price of $2.1437 as of 2026-10-29; higher-volume pricing was not supplied. Availability and lead time must be confirmed with the selected authorized distributor before procurement.
TJA1051T - High-Speed CAN Transceiver | NXP Semiconductors
The NXP Semiconductors TJA1051T is an active high-speed CAN transceiver that interfaces a CAN protocol controller with a physical two-wire CAN bus. The device provides differential transmit and receive capability for automotive high-speed CAN systems and is supplied in an 8-pin SOIC package. NXP identifies the TJA1051 as backward compatible with the TJA1050, while the TJA1051T/3 and TJA1051TK/3 variants support direct interfacing with microcontrollers operating from supply voltages as low as 3 V. The verified product information confirms active lifecycle status and links to the manufacturer data sheet. A CAN transceiver is the physical-layer interface between a digital CAN controller and the wired CAN network. It converts controller logic levels into differential bus signals and converts received bus levels into a logic signal understood by the controller. The two-wire CAN bus consists of CANH and CANL conductors, allowing multiple nodes to communicate over a shared differential network while reducing sensitivity to common-mode noise. The TJA1051 family is intended for high-speed in-vehicle communication systems where robust differential signaling and direct integration with automotive microcontrollers are important. The manufacturer describes the TJA1051T as a high-speed CAN transceiver, and its compatibility with the TJA1050 provides a documented migration path for designs that retain an existing SOIC-8 footprint and pin arrangement. The TJA1051T/3 variant is the 3 V-compatible option when the connected CAN controller uses a lower supply voltage. Electrical operating details such as maximum data rate, supply range, transmitter propagation delay, receiver thresholds, bus-fault tolerance, ESD ratings, thermal limits, and package dimensions were not included in the supplied search excerpts. Those values are therefore not restated here; engineers should verify them in the NXP TJA1051 manufacturer data sheet before release. The data sheet also distinguishes standard, /3, and /E product variants, which should not be treated as identical ordering codes. TJA1051T is typically positioned between a CAN-capable microcontroller and the CANH/CANL bus network. Practical implementations require correct termination, common-mode grounding, protection strategy, and transceiver-loop layout. The SOIC-8 package makes the device suitable for conventional surface-mount PCB assembly, although production designs must use the exact land pattern and pin definitions specified by NXP. This page consolidates the verified NXP product-page information, manufacturer data-sheet link, distributor references, and identified same-footprint alternatives. It also distinguishes documented TJA1051 variants and highlights the engineering trade-offs between the standard TJA1051T, the 3 V-compatible TJA1051T/3, and the Silent Mode TJA1051T/2Z. Pricing, availability, and detailed electrical ratings require confirmation from current authorized distribution channels as of 2026-10-28.
TJA1051T/1J - 5 Mbit/s High-Speed CAN Transceiver | NXP
The NXP TJA1051T/1J is a 5 Mbit/s high-speed CAN transceiver with 5 V operation, differential transmit and receive capability, and an 8-pin SOIC package. It interfaces a CAN protocol controller to a physical two-wire CAN bus and is associated with automotive applications. The device is also described as normal-mode, SILENT-mode-capable and AEC-Q100 qualified in the supplied component data. A CAN transceiver is the physical-layer interface between a microcontroller or dedicated CAN controller and the CAN bus. The controller generates and interprets logic-level CAN TX and RX signals, while the transceiver converts those signals into the differential CANH and CANL bus signals. A high-speed CAN physical layer supports differential signaling, noise rejection and reliable communication over twisted-pair wiring. The TJA1051T family is positioned for high-speed CAN networks at data rates up to 5 Mbit/s. The verified component listing identifies a nominal 5 V supply, normal/silent operation, 8-pin SO packaging and tape-and-reel ordering for TJA1051T/1J. NXP also states that TJA1051T is backward compatible with the TJA1050, which is important when upgrading an existing CAN interface. The TJA1051 provides separate transmit-dominant, silent and receive behavior for bus management. Silent mode can be useful when a node must monitor or receive without driving the bus, although network software must coordinate this state with other nodes to avoid hidden transmitter conflicts. The device should be paired with an appropriate CAN controller, bus termination, common-mode protection and a correctly decoupled 5 V supply. Typical installations include automotive body, powertrain-adjacent, gateway and diagnostic networks; industrial automation equipment; elevator and building-control systems; and embedded CAN gateways. The 5 Mbit/s capability suits short, well-terminated, high-quality CAN networks where maximum latency is more important than long cable distance. In every case, PCB layout, grounding and bus protection remain critical. For layout, place the transceiver close to the bus connector, provide a continuous ground reference, route CANH and CANL as a coupled pair, and place termination only at the physical ends of the bus. Avoid long stubs between the transceiver and connector. Power filtering and common-mode chokes may be needed when the cable leaves the controlled PCB environment. This page combines the verified NXP and distributor information with practical selection, layout and sourcing guidance. It also distinguishes verified facts from parameters that require confirmation from the complete manufacturer datasheet or current distributor inventory before design release.
TJA1051T/1U - High-Speed CAN Transceiver | NXP | Automotive
The NXP Semiconductors TJA1051T/1U is a high-speed CAN transceiver in an 8-pin SO package. It provides the physical-layer interface between a microcontroller-based CAN protocol controller and a two-wire CAN bus, combining differential transmit and receive capability for automotive high-speed CAN networks. The available manufacturer information identifies the TJA1051 family as active and specifically describes the TJA1051T as backwards compatible with the TJA1050. A CAN transceiver, also called a CAN physical-layer interface, converts logic-level TXD and RXD signals into the differential CANH and CANL bus signals. It belongs to the hierarchy CAN transceiver > CAN physical-layer interface > network interface IC > interface IC > semiconductor. This physical-layer device complements a CAN controller such as those integrated into automotive microcontrollers; it does not replace the protocol controller or its message-handling firmware. The TJA1051T family includes differentiated order-code options for specific design constraints. The NXP datasheet states that TJA1051T/3 and TJA1051TK/3 support direct interfacing with microcontrollers operating from supply voltages down to 3 V. It also states that TJA1051T/E can be switched into a very low-current Off mode. These options provide distinct low-voltage-interface or low-power-selection paths, while TJA1051T/1U remains the specifically requested 8-SO device. The transceiver's two-wire CAN interface and differential signaling support communication over a shared bus designed for high-speed automotive data exchange. Exact data-rate limits, loop-delay timing, bus fault levels, supply range, transceiver state currents, and ESD ratings are not included in the supplied verified snippets, so they must be confirmed in the NXP datasheet before release of a safety- or production-critical design. Typical uses include distributed vehicle networking, body and chassis control modules, powertrain-related control units, gateway electronics, and industrial CAN equipment connected to the same physical bus concept. In each application, the microcontroller handles protocol framing while the TJA1051 family handles the electrical interface to CANH and CANL. PCB implementation requires an 8-SO footprint, correct termination and common-mode handling, and a CAN bus layout that minimizes radiated emissions and susceptibility. Designers should also verify the exact logic and enable behavior of TJA1051T/1U because the requested order code differs from the explicitly documented /3 and /E variants. This page consolidates the verified NXP product information, official datasheet link, distributor identification, package details, and sourced drop-in alternatives. It also highlights which electrical ratings remain unverified so engineers can compare procurement options without mistributing catalog snippets for complete device specifications.
TJA1051T/2Z - 5 Mbit/s Silent-Mode CAN Transceiver | NXP
NXP Semiconductors TJA1051T/2Z is a 5 Mbit/s high-speed CAN transceiver with Silent Mode, packaged in an 8-pin SOIC for interface bridging between a CAN protocol controller and a physical two-wire CAN bus. The verified distributor listing identifies the /2 ordering option as a Silent-Mode variant, while the manufacturer document covers the TJA1051T family and its compatibility with TJA1050. Its differential transmit and receive arrangement supports automotive and industrial Controller Area Network nodes. A CAN transceiver is the physical-layer interface within a Controller Area Network. It converts controller TXD and error-indicator signals into differential bus output, then converts differential bus levels into RXD data for the protocol controller. This device sits between digital microcontroller I/O and the CAN_H and CAN_L network conductors, combining bus-driver, receiver, and control functions in one IC. The TJA1051T/2Z headline characteristics are a maximum listed data rate of 5 Mbit/s and an 8-pin SOIC package. Silent Mode provides an operating state identified by the verified product listing, but the supplied excerpts do not quantify its input, output, or supply current. The manufacturer also states that the TJA1051T is backward compatible with the TJA1050, which is important when upgrading an existing CAN node without changing its controller-facing interface. The TJA1051 family targets high-speed CAN networks, including automotive systems, where robust differential signaling and transceiver integration simplify node construction. Differential bus operation rejects common-mode noise better than a single-ended interface when the network, termination, grounding, and connector implementation are correctly designed. This makes the part suitable for vehicle body electronics, industrial automation equipment, embedded controllers, and CAN-based sensors. The primary design consideration is preserving compatibility at both the software and physical layers. A replacement must match the SOIC-8 footprint, pin functions, supply expectations, bus timing, and controller logic. Bus termination, common-mode range, loop delay, recessive/dominant behavior, and maximum cable length must be checked against the complete network design rather than inferred solely from the 5 Mbit/s headline rate. For sourcing and engineering context, this page combines the exact verified distributor identity, manufacturer datasheet link, availability claims, family-level compatibility information, and practical design guidance. It separates verified facts from unspecified electrical details so procurement teams can review TJA1051T/2Z without relying on unverified substitutions.
TJA1051T/3/1J - 5 Mbit/s CAN Transceiver | NXP
The NXP Semiconductors TJA1051T/3/1J is a high-speed CAN bus transceiver with a maximum CAN data rate of 5 Mbit/s, a 5.5 V supply rating, and direct support for microcontroller I/O levels from 3 V to 5 V. The device is supplied in an 8-pin SOIC package and provides the physical-layer interface between a CAN protocol controller and a two-wire CAN bus. A CAN transceiver is an interface IC within the CAN controller hierarchy and the broader industrial and automotive networking ecosystem. It converts the controller's transmit and receive logic signals into differential CAN bus levels and presents received bus data to the controller. The TJA1051 family is intended for high-speed CAN networks and provides passive behavior on the bus when its supply is off. Key features include a 5 Mbit/s maximum data rate, improved electromagnetic compatibility, enhanced electrostatic-discharge performance, and compatibility with 3 V to 5 V microcontroller supply levels. The VIO-related version supports direct connection to microcontrollers operating at those lower I/O voltages, which simplifies interfacing between a 5 V transceiver supply and a 3.3 V CAN controller. Technically, the transceiver bridges a logic-domain CAN controller and a differential physical bus. Its TXD input accepts controller command data, while RXD reports received bus state to the controller. CANH and CANL carry the complementary differential signal, and the S input supports standby behavior when the device supports that operating mode. The manufacturer datasheet specifically notes backwards compatibility with the TJA1050. Typical uses include automotive body and comfort electronics, industrial automation controllers, building automation equipment, robotics, diagnostic interfaces, and embedded CAN gateways. The device is particularly appropriate when a 3.3 V controller must communicate through a 5 V CAN transceiver without adding level-shifting circuitry between TXD, RXD, and S. Designers should provide the bus termination and common-mode installation required by the CAN network rather than relying on the transceiver for termination. Decoupling close to VCC and VIO, controlled bus stubs, correct grounding, and an appropriate CAN controller timing configuration are essential for reliable operation. This page consolidates the verified manufacturer and distributor information, practical application guidance, parameter comparisons, and verified drop-in alternatives. It also distinguishes documented TJA1051 family differences from broader functional equivalents so engineers can assess PCB compatibility without confusing protocol speed or standby behavior with physical pin compatibility.
TJA1051T/E/1J - 5Mbit/s CAN Transceiver | NXP Semiconductors
The NXP Semiconductors TJA1051T/E/1J is a high-speed CAN transceiver with a maximum data rate of 5Mbit/s, differential transmit and receive capability, Silent mode, Off mode, and an 8-pin SOIC package. It provides the physical-layer interface between a CAN protocol controller and a two-wire automotive CAN bus. A CAN transceiver is an interface IC within the broader hierarchy of CAN interface ICs, network interface devices, interface integrated circuits, and semiconductors. It converts logic-level TXD and RXD signals from a CAN controller into the balanced differential signaling used on a CAN bus, while converting received bus levels back into a controller-compatible RXD signal. The TJA1051T/E/1J is intended for high-speed CAN systems in automotive and industrial environments. The verified product information identifies support for data rates up to 5Mbit/s, Silent mode, and Off mode. Silent mode can place a node into a state that does not actively drive the bus while retaining the ability to receive according to the device behavior. Off mode provides a very low-current shutdown state. The TJA1051T/E family is also identified as backwards compatible with the TJA1050, which is important for designs migrating from that established high-speed CAN transceiver. The TJA1051T/E/1J is the SOIC-8 version of the third-generation TJA1051 family. NXP describes the TJA1051 as a high-speed CAN transceiver for automotive applications with enhanced electromagnetic compatibility and electrostatic-discharge protection. The differential bus interface reduces susceptibility to common-mode noise, while the transceiver's transmit and receive stages provide the physical signaling required for reliable communication over long, multiconductor harnesses. Typical uses include automotive body-control modules, powertrain controllers, instrument clusters, electronic control units, industrial automation equipment, robotics controllers, and CAN-based sensors. A CAN controller supplies the TXD input and receives RXD, while the TJA1051T/E/1J connects those digital signals to the CANH and CANL bus conductors. The bus must also include the appropriate termination network, decoupling, and protection arrangement specified by the manufacturer. A critical design consideration is the difference between TJA1051T/E/1J and TJA1051T/3/1J. The verified NXP information specifically associates direct interfacing with 3V microcontrollers with the TJA1051T/3 and TJA1051TK/3 variants, not the standard TJA1051T/E/1J. The enable and logic-level behavior should therefore be checked against the controller supply voltage and the existing PCB before substitution.

TJA1052IT - Isolated High-Speed CAN Transceiver SOIC-16 | NXP
The NXP TJA1052IT is a galvanically isolated high-speed CAN transceiver that provides a robust interface between a CAN protocol controller and the physical two-wire CAN bus, housed in a 16-pin SO package and specifically targeted at Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) applications. An isolated CAN transceiver is a specialized interface IC that combines a high-speed CAN physical layer with on-chip galvanic isolation, typically using integrated coreless transformer or silicon-dioxide (SiO2) dielectric barriers to withstand high common-mode transients in automotive high-voltage environments. Within the broader semiconductor taxonomy, the TJA1052IT sits in the hierarchy isolated CAN transceiver -> CAN transceiver -> CAN interface IC -> automotive interface IC -> power management & signaling semiconductor. Isolation eliminates ground loops between the low-voltage domain (MCU/host) and the high-voltage CAN bus, which is essential when the ECU and chassis sit at different potentials. Key specifications include integrated galvanic isolation rated to withstand high common-mode voltages, support for CAN data rates up to 1 Mbit/s per ISO 11898-2, a wide supply range on the bus side, and very low loop delay suitable for time-triggered CAN (CAN FD-ready) networks. The 16-pin SO package exposes dedicated pins for VCC (logic-side supply), VBUS (bus-side supply), TXD, RXD, CANH, CANL, and the integrated isolation barrier. Architecturally, the TJA1052IT integrates a digital isolator and a CAN transceiver die, with the isolation barrier providing reinforced insulation. This monolithic approach reduces PCB area versus a discrete transceiver + digital isolator solution and improves reliability by eliminating intermediate interconnects. Typical applications include EV/HEV battery management systems, on-board chargers (OBC), DC fast-charging communication links (ISO 15118 PLC not included), traction inverter CAN nodes, and industrial CAN networks requiring reinforced isolation. When designing with the TJA1052IT, place decoupling capacitors close to both VCC and VBUS pins and respect the creepage/clearance rules on the PCB around pins straddling the isolation domain. The device is drop-in compatible with the TI ISO1042 in 16-SO footprint, simplifying second-source strategies. This page synthesizes distributor pricing, drop-in alternatives, and design notes for the TJA1052IT that are not always presented together in the manufacturer datasheet.
TJA1052IT-1Y - Galvanically Isolated HS CAN Transceiver | NXP
The NXP Semiconductors TJA1052IT-1Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver housed in a 16-pin Small Outline (SO-16) package. It provides an isolated interface between a CAN protocol controller and the physical two-wire differential CAN bus, integrating on-chip galvanic isolation that traditionally required a separate digital isolator plus a CAN transceiver. The part is specifically targeted at Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV), where robust isolation between high-voltage traction domains and low-voltage ECU communication is mandatory. A CAN transceiver is the physical-layer bridge inside an in-vehicle network: it converts the differential logic-level signals from a CAN controller (TXD, RXD) into the bus-side differential voltage on the CANH and CANL lines that meet ISO 11898-2/-5, while protecting the host controller from bus-level transients. The TJA1052i family adds integrated digital isolation (typically using on-chip coreless transformer technology) to that bridge, replacing a two-chip solution (isolator + transceiver) with a single component and simplifying PCB layout while improving common-mode transient immunity (CMTI) in motor-drive environments. Key features include ISO 11898-2/-5 compliant high-speed CAN data rates up to 1 Mbit/s, integrated galvanic isolation rated for 1 kV (digital isolator channel rating per the part classification), tight loop delay for time-triggered CAN (TTCAN) operation, and integrated bus-side protection for harsh automotive electrical environments. The TJA1052i is designed to operate over the full automotive temperature range and supports low-power standby modes for battery-friendly quiescent current draw when the bus is silent. The architecture uses NXP's high-speed CAN transceiver core combined with on-chip galvanic isolation cells, removing the need for external optocouplers or digital isolator ICs while providing the same reinforced isolation barrier between the CAN controller domain and the bus domain. This two-domain split is essential in EV/HEV powertrain ECUs where the bus may sit on a high-voltage referenced plane. Typical applications include EV and HEV battery management system (BMS) CAN nodes, onboard chargers, DC-DC converter telemetry, electric power steering (EPS) communication links, and industrial CAN-isolated gateways that must bridge different ground domains. Designers use the TJA1052IT-1Y where ISO 11898 bus timing must be preserved across an isolation barrier without adding a discrete isolator stage. A key design consideration is that the bus-side and logic-side grounds must remain galvanically separate; do not bypass the isolation by shorting the two ground planes. Also confirm the 1 kV channel rating meets the end-application's reinforced or basic isolation requirement before reuse in higher-voltage systems. This page synthesizes the NXP datasheet, current distributor pricing, and a curated set of drop-in alternatives that share the same SO-16 footprint - content not aggregated on any single manufacturer or distributor page.
TJA1052IT-5Y - Isolated High-Speed CAN Transceiver 5Mbps AEC-Q100 | NXP
The NXP TJA1052IT-5Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver that provides a 5 Mbps interface between a CAN protocol controller and the physical two-wire CAN bus, housed in a 16-pin SOIC package with 5 kV RMS isolation. It targets Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), and any application requiring reinforced isolation between bus nodes. The integrated digital isolator and CAN transceiver in one package eliminates the need for a discrete isolator plus discrete transceiver, cutting board area roughly in half and simplifying EMC design. A CAN transceiver is a physical-layer (PHY) device that converts differential CAN logic levels from a microcontroller's CAN controller into the dominant/recessive bus signaling required by ISO 11898-2, while providing bus-side fault protection and EMC robustness. The TJA1052IT specifically adds on-chip galvanic isolation - replacing a two-chip solution (isolator + CAN transceiver) with a single device - and is part of the broader hierarchy: CAN transceiver -> interface IC -> integrated circuit. Key features include data rates up to 5 Mbps (CAN FD capable), an isolation voltage of 5000 V RMS for 1 minute per UL 1577, bus fault protection from -27V to +40V, an operating supply range that supports both 1.8V/3.3V/5V MCU sides, and AEC-Q100 qualification for automotive environments. A low-power standby mode with bus wake-up detection is also present, achieved through a dedicated STBY pin and a remote wake-up pattern recognizer compliant with ISO 11898-5. The TJA1052IT uses NXP's integrated capacitive-coupled isolation technology plus a proven CAN PHY, achieving low loop delay under 200 ns - critical for CAN FD frames at the maximum payload phase. Compared with discrete optocoupler + CAN transceiver solutions, the integrated approach reduces propagation delay variation over temperature by a factor of 2-3, improving timing margin in large or noisy automotive networks. Typical applications include EV/HEV battery management system (BMS) bus isolation, OBC (on-board charger) to VCU communication, industrial CAN bus nodes requiring 5 kV isolation (solar inverters, motor drives), EV charging stations with isolated CAN, isolated industrial sensor hubs, and automotive ECU-to-ECU isolation. A key design consideration is the supply topology: the device has two VCC rails - VCC1 (logic/microcontroller side, 2.5V-5.5V) and VCC2 (bus-side, 4.5V-5.5V) - each requiring local decoupling. Designers should follow NXP application note AN11253 for PCB layout, especially maintaining a creepage/clearance margin under the isolation barrier. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including structured comparison with the TI ISO1042DW as identified in NXP community threads.
TJA1052IT/2Y - Isolated High-Speed CAN Transceiver | NXP
The NXP TJA1052IT/2Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver that provides a 2.5 kVrms isolated interface between a CAN protocol controller and the physical two-wire CAN bus, housed in a 16-pin SO (SOIC-16, 300 mil) package with capacitive (galvanic) isolation integrated on-chip. The device operates from a 3 V to 5.25 V supply on the logic/microcontroller side and supports a CAN data rate of up to 5 Mbps, making it suitable for Classic CAN and CAN FD frame formats. The integrated isolation removes the need for an external digital isolator + isolated DC-DC combination in many designs, reducing BOM count and PCB area. What is an isolated CAN transceiver? A CAN transceiver is the physical-layer bridge between a CAN controller (typically embedded in a microcontroller) and the differential CAN bus lines (CANH/CANL). A galvanically isolated version inserts a high-voltage barrier - here implemented via on-chip capacitive coupling - between the logic domain and the bus domain, breaking ground loops and protecting low-voltage MCU I/O from high-voltage transients common in automotive 12 V/24 V powertrain systems and industrial installations. Key features of the TJA1052IT/2Y include 1/1 unidirectional channel count, 2.5 kVrms isolation voltage rating, 5 Mbps maximum data rate, a standby mode for low quiescent current, and compatibility with 1.8 V and 3.3 V controller logic via separate VIO/VCC rails. The device is specifically targeted at Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), and other automotive applications where high-speed CAN communication must coexist with high-voltage battery and inverter systems. Typical applications include EV/HEV battery management system (BMS) communication gateways, on-board chargers (OBC), traction inverter CAN interfaces, industrial CAN bus nodes requiring reinforced insulation, and isolated debug or service interfaces for automotive ECUs. When designing with the TJA1052IT/2Y, engineers should provide local decoupling on both the logic-side and bus-side supplies, observe creepage/clearance for the 2.5 kV isolation barrier, and verify the standby-mode behavior against the system power-state diagram. This page synthesizes distributor pricing, drop-in alternatives, and practical isolation-layout design notes not consolidated in the standalone manufacturer datasheet.
TJA1055T/1J - 125 kBd Fault-Tolerant CAN Transceiver

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/3/1J - 125 kBd Fault-Tolerant CAN Transceiver | NXP
NXP Semiconductors TJA1055T/3/1J is an enhanced fault-tolerant Controller Area Network transceiver with differential transmit and receive capability, optimized for low-speed CAN communication up to 125 kBd. The device operates from a 5 V to 28 V supply range, includes a 3 V VIO variant for interfacing with low-voltage CAN controllers, and is offered in a 14-pin SO surface-mount tape-and-reel package. 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.
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.

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.
