TJA1044T/1Z

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

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

TJA1044VT/3Z - 5Mbps VeLIO CAN Transceiver | NXP
TJA1044VT/3Z

TJA1044VT/3Z - 5Mbps VeLIO CAN Transceiver | NXP

NXP Semiconductors TJA1044VT/3Z is a VeLIO-certified, 5 Mbps high-speed CAN transceiver for automotive applications, with standby mode and a 5 V supply in an 8-pin SO package. It provides the physical-layer interface between a CAN protocol controller and a two-wire CAN bus, combining differential transmit, differential receive, bus protection, and low-power standby operation in one device. A CAN transceiver is the physical-layer component between a digital controller and the CAN bus. It converts controller logic into a differential signal for transmission, converts bus differential voltage into logic levels for reception, and provides the interface robustness required by automotive networking. The TJA1044V belongs to NXP's Mantis family of high-speed CAN transceivers and is intended for CAN systems using 5 V transceiver supply rails. The principal verified features of the TJA1044VT/3Z include operation up to 5 Mbps, standby-mode support, VeLIO certification, an automotive AEC-Q100 classification, and an 8-pin SO package. Standby operation lets a system reduce current consumption when communication is temporarily unnecessary, which is useful in vehicle electronics where sleep behavior and predictable power management affect the overall power budget. The automotive qualification indication makes the device relevant to body, chassis, powertrain-adjacent, and other vehicle-network designs that require an AEC-Q100-class CAN physical layer. The device interfaces a CAN controller, commonly a microcontroller or dedicated CAN controller, to the CANH and CANL bus conductors. Differential signaling improves common-mode rejection and supports reliable communication over longer harnesses than a single-ended implementation. Designers must still account for bus topology, termination, common-mode voltage, ESD exposure, ground offsets, and the timing relationships among the transceiver, controller, and network. The manufacturer's datasheet is the controlling source for the exact pin functions, electrical limits, timing limits, and application circuit. Typical uses include automotive body-control modules, powertrain controllers, gateway computers, comfort systems, diagnostic equipment, and other ECUs that communicate over a high-speed two-wire CAN network. It can also be considered for industrial or transportation systems only after confirming that the environmental, qualification, supply, and bus-performance requirements match the intended deployment. A 5 Mbps CAN link permits substantially more traffic than classic low-speed CAN while retaining the robustness and arbitration characteristics that make CAN common in vehicle networks. For implementation, place the transceiver close to the CAN connector and route CANH and CANL as a differential pair with continuous reference planes and minimized stubs. Connect the bus termination network at the physical ends of the network, maintain the specified common-mode operating range, and provide the datasheet-recommended transceiver decoupling. Verify standby-entry and wake-up behavior in the system power state machine, and validate ESD, conducted-emissions, immunity, ground-offset, and fault-recovery behavior at the vehicle level. This product page combines verified manufacturer and distributor information with lifecycle status, procurement guidance, application engineering context, and package-aware comparison data. It distinguishes verified specifications from parameters that require confirmation in the current NXP datasheet, helping engineers make sourcing and design decisions without treating undocumented assumptions as guaranteed facts.

TJA1044VTKZ - 1Mbit/s CAN Transceiver with Standby | NXP
TJA1044VTKZ

TJA1044VTKZ - 1Mbit/s CAN Transceiver with Standby | NXP

The NXP Semiconductors TJA1044VTKZ is a high-speed CAN transceiver with standby mode, packaged in an 8-HVSON (3x3 mm) surface-mount package with an exposed thermal pad. It delivers a 1 Mbit/s differential data rate, operates from a 5 V transceiver supply with separate VIO logic support, and carries a moisture sensitivity level of 1 with a 260 °C peak reflow rating. The part is VeLIO certified and ships in tape-and-reel form. A CAN transceiver is a physical-layer interface IC that converts the logic-level TXD and RXD signals of a CAN protocol controller into the differential CANH and CANL wires of a two-wire CAN bus, and converts bus levels back into a digital receive signal. Within the device hierarchy, a CAN transceiver is a bus interface IC, a subcategory of interface ICs, sitting between a microcontroller or standalone CAN controller and the physical network. The TJA1044V belongs to NXP's Mantis family of high-speed CAN transceivers aimed at ISO 11898-2 style automotive and industrial networks. Key features of the TJA1044VTKZ include a standby (S) control input that places the transceiver into a low-power state without fully removing it from the bus, a separate VIO pin for interfacing to 3.3 V microcontrollers, low-current dominant and recessive output states, and short-circuit and thermal protection on the bus pins. VeLIO certification indicates conformance with NXP's CAN transceiver qualification criteria for high-volume automotive deployments. Technically, the device is a half-duplex transceiver: in transmit mode it drives the differential bus, and in receive mode it senses the bus and outputs a dominant/recessive logic level on RXD. The 8-HVSON package keeps the footprint small enough for space-constrained electronic control units while the exposed pad provides a low-thermal-resistance path for the dissipation that occurs when the driver is active on a shorted or heavily loaded bus. Typical applications include automotive body and comfort control modules, head units and body domain controllers, EV and e-bike powertrain controllers, industrial CAN gateways, and medical or instrumentation equipment that uses CAN as a backplane. Because the transceiver is a bus-side device rather than a logic device, its supply, ground, and bus connections dominate the layout requirements of the surrounding board. Design notes: place a 100 nF and 1 uF decoupling pair directly between VCC and the exposed GND pad, keep the CANH and CANL traces short and matched, and provide a 60 ohm split termination at each end of the bus. Leave the S pin at a defined level so the node does not enter standby unintentionally during reset, and confirm the VIO level matches the CAN controller supply. This page consolidates distributor pricing, verified package and ordering information, drop-in alternatives and practical design notes in one place, so engineers can qualify the TJA1044VTKZ for an existing 8-HVSON CAN footprint without re-reading several distributor listings.

TJA1044VTZ

TJA1044VTZ - 5Mbps CAN Transceiver | NXP | Automotive

NXP Semiconductors TJA1044VTZ is an automotive high-speed CAN transceiver with standby mode, one transmitter, one receiver, and a maximum data rate of 5 Mbps in an 8-pin SOIC package. It operates from a 4.75 V to 5.25 V supply, supports a half-duplex CANbus connection, and has a junction-temperature range of -40°C to 150°C. A CAN transceiver is the physical-layer interface between a Controller Area Network protocol controller and the differential two-wire CAN bus. Within the hierarchy of CAN interface ICs, transceivers convert controller logic levels into bus voltages and convert received bus levels back into digital RXD signals. The TJA1044 belongs to NXP's Mantis high-speed CAN family and is intended primarily for automotive electronic systems. Key verified characteristics include 5 Mbps operation, normal and standby operating modes, 300 mV receiver hysteresis, 4.75 V to 5.25 V supply operation, and an automotive AEC-Q100 classification. The single-transmitter, single-receiver arrangement supports half-duplex CAN communication through one shared bus interface rather than providing separate independent send and receive channels. The TJA1044 family interface uses differential CANH and CANL bus connections to reject common-mode noise while communicating over a noisy vehicle network. Its 300 mV receiver hysteresis helps determine valid bus signaling, while standby mode provides a control path for reducing activity when the node is not participating in communication. Exact loopback, propagation-delay, bus-fault, and electrical-characteristic limits are not available in the supplied snippets and must be confirmed in the manufacturer datasheet. Typical uses include automotive body-control modules, powertrain controllers, gateway electronics, comfort systems, and other ECUs connected to high-speed CAN networks. A controller such as a CAN-capable microcontroller connects through TXD and RXD, while TJA1044VTZ handles the physical bus. System designers must verify bus topology, termination, transceiver timing, fault behavior, standby polarity, and thermal performance against the complete datasheet. For PCB implementation, use the manufacturer reference layout and route CANH and CANL as a tightly coupled differential pair away from switching nodes and high-current paths. Place protection and common-mode-choke components where their impedance and capacitance remain compatible with the target CAN bit rate and network topology. This product record consolidates verified manufacturer and distributor facts, source links, practical design guidance, and clearly marked missing electrical details. It distinguishes documented TJA1044VTZ characteristics from parameters requiring review of the full NXP datasheet before release to production.

TJA1046TKZ - Dual 5 Mbps CAN Transceiver | NXP
TJA1046TKZ

TJA1046TKZ - Dual 5 Mbps CAN Transceiver | NXP

The NXP TJA1046TKZ is a dual high-speed CAN transceiver in a 14-HVSON surface-mount package, integrating two independent interfaces between CAN protocol controllers and physical two-wire CAN buses. Each channel supports differential transmit and receive operation up to 5 Mbps and includes standby mode for systems requiring controlled low-power operation. The -5.25 V part number identifies the NXP ordering variant associated with the provided TJA1046TKZ product data. A CAN transceiver is an interface IC within the network-interface and automotive electronics hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into differential bus voltages, while converting bus levels back into logic-compatible receive signals. A CAN controller handles frames, arbitration, acknowledgments, and protocol error management; the physical-layer transceiver connects that controller to the wired CAN-Bus network. The verified product information identifies two fully independent TJA1044GT transceiver sections, high-speed automotive CAN operation, differential bus signaling, and standby capability. The dual-channel architecture reduces the component count where two CAN nodes or bus segments must share one physical PCB area. The 14-HVSON package is only 3 mm by 4.5 mm according to the DigiKey listing, supporting compact automotive and industrial electronics layouts without combining two separate transceiver packages. TJA1046TKZ is appropriate for automotive body, chassis, powertrain-adjacent, and industrial control networks when two high-speed CAN physical-layer interfaces are required. Dual-channel integration can simplify component placement and reduce PCB routing effort, although each channel still requires correct bus termination, common-mode behavior, electromagnetic-compatibility layout, and decoupling. The CAN bus must use twisted-pair wiring and appropriate 120-ohm termination where specified by the network design. The principal design consideration is to follow NXP's specified pin, supply, ground, input, output, and exposed-pad connections exactly. Each transceiver must be placed close enough to its connector or bus interface for short differential traces, while analog and power-return paths should remain appropriately partitioned. Because the supplied search results do not expose complete electrical limit tables, pin mapping, package dimensions, or absolute maximum ratings, engineers should use the official NXP TJA1046 datasheet for final schematic and layout sign-off. This page consolidates the verified NXP product description, distributor package identification, official datasheet link, purchasing sources, and replacement-validation gaps. It also distinguishes confirmed dual 5 Mbps CAN functionality from unverified assumptions about voltage tolerances, loop delay, bus fault handling, and exact exposed-pad requirements.

TJA1046VTKZ - Dual HS CAN Transceiver w/ Standby | NXP | Automotive

The NXP TJA1046VTKZ is a dual high-speed CAN transceiver housed in a 14-pin HVSON (3x4.5 mm) package with exposed pad, providing two independent interfaces between a CAN protocol controller and the physical two-wire CAN bus. Each channel is functionally equivalent to a TJA1044GT high-speed CAN transceiver, supporting HS-CAN data rates per ISO 11898-2/5 and ISO 11898-2:2016 in automotive networks. The device is VeLIO compliant and qualified for automotive body and powertrain networks. A CAN transceiver is a physical-layer (PHY) interface IC that translates the differential CANH/CANL bus voltages required for robust in-vehicle networking into standard digital TX/RX logic levels for a microcontroller's CAN protocol controller. It sits between the MCU's CAN module (data link layer) and the wired CAN bus, providing the dominant/recessive bit signaling, common-mode rejection, bus fault protection, and ESD handling required by ISO 11898. The TJA1046VTKZ integrates two such PHYs on one die, saving board area versus discrete single-channel transceivers in zonal and gateway ECUs. Key features of the TJA1046VTKZ include very low-current standby mode with bus wake-up (per ISO 11898-5), thermal protection, bus dominant time-out, and high ESD robustness on the bus pins. Both channels share the same standby/wake behavior; the device targets automotive ECUs requiring dual CAN channels such as body control modules, gateway ECUs, and ADAS sensor aggregation nodes. The HVSON-14 (3x4.5) exposed-pad package provides a low thermal resistance path, which is critical for under-hood and high-ambient-temperature installations. The architecture pairs two independent TJA1044-style transceivers on a common die, with shared thermal shutdown and independent TXD/RXD/standby control per channel. Each channel includes a low-drop voltage regulator for internal logic, slope control for reduced EMI, and an integrated bus termination concept suitable for HS-CAN nodes. Per the NXP datasheet the part is optimized for automotive EMC performance including SAE J2962-related conformance expectations. Typical applications include dual-CAN automotive ECUs (body control modules, gateways, instrument clusters), industrial CAN nodes with dual buses (CANopen, DeviceNet), and OBD-II dual-channel diagnostic interfaces. The standby mode makes it suited for always-on networks that must wake on bus activity. When designing with the TJA1046VTKZ, ensure the exposed pad is soldered to a sufficiently large copper pour (>= 50 mm^2) and that the bus stubs to CANH/CANL are kept below the ISO 11898-2 maximum length for the chosen data rate. A common-mode choke and split termination improve EMI/ESD margin.

TJA1048

TJA1048 - Dual High-Speed CAN Transceiver, SOIC-14 | NXP

The NXP Semiconductors TJA1048 is a dual high-speed Controller Area Network (CAN) transceiver with Standby mode that provides the physical interface between a CAN protocol controller and the differential two-wire CAN bus in automotive and industrial systems. Each of the two independent transceiver channels integrates a CAN protocol controller side (TXD/RXD) and a bus side (CANH/CANL) differential driver/receiver, supporting the ISO 11898-2:2016 high-speed CAN physical layer standard. The device is housed in a 14-pin SOIC package, with the TJA1048T,118 variant supplied on tape-and-reel for high-volume assembly. A high-speed CAN transceiver (HS-CAN transceiver) is the physical-layer interface IC that converts digital transmit/receive logic levels from a CAN controller (typically an MCU or SBC) into the differential dominant/recessive voltage signaling on a CAN bus, while also providing bus fault protection, ESD robustness, and low-power modes. The transceiver operates at the lowest tier of the OSI layered model, beneath the CAN data link layer (typically handled in the MCU's CAN controller). The TJA1048 belongs to NXP's third-generation HS-CAN family, offering improved electromagnetic compatibility (EMC) and quiescent-current performance compared with first-generation devices such as the TJA1040, while combining two complete transceivers into a single package to save board space on dual-bus automotive ECUs. Key features of the TJA1048 include very low quiescent current in Standby mode for battery-connected nodes, robust ±8 kV HBM ESD handling on the bus pins, bus terminal short-to-battery and short-to-ground protection, thermal shutdown, and a transmit-data (TXD) dominant-timeout function that prevents the bus from being permanently driven dominant by a stuck TXD pin. The split termination pin (STB/VIO reference) and the dedicated Standby control input allow the system MCU to selectively power down one or both channels when the bus is idle. The TJA1048 architecture places each transceiver channel as an independent differential line driver with slope-controlled output stages to limit electromagnetic emissions and meet automotive OEM EMC requirements. A common-mode stabilization circuit maintains bus symmetry across wide ground-offset conditions encountered in 12 V and 24 V vehicle networks, allowing reliable communication even during transient events such as engine cranking or load dump. Typical applications include automotive body-control modules, gateway ECUs that bridge CAN and CAN-FD buses, dual-channel infotainment network nodes, industrial CAN-IO modules with redundant bus interfaces, and OBD-II diagnostics adapters that monitor two independent CAN networks simultaneously. The device is qualified per AEC-Q100 and supports the operating temperature range required under the -40 C to +125 C automotive grade. When designing with the TJA1048, pay attention to bus termination: a 120 ohm split-termination network (60 ohm plus 60 ohm with a capacitor to ground) at each end of the bus is recommended to suppress common-mode emissions. The Standby pin transitions must respect the minimum bus-idle detection time before remote wake-up is acknowledged, otherwise the bus remains silent. According to NXP, unused channels should still have their TXD tied high (recessive) to avoid accidental bus dominance.

TJA1048T - Dual 1Mbit/s CAN Transceiver with Standby | NXP

NXP Semiconductors TJA1048T is a dual high-speed CAN transceiver with two independent CAN channels, differential transmit and receive capability, and support for CAN data rates up to 1 Mbit/s. The device is packaged in a 14-pin SO package identified by distributors as 14-SO and is intended to interface a CAN protocol controller with a physical two-wire CAN bus in automotive and industrial high-speed CAN systems. A CAN transceiver is a physical-layer interface IC that converts logic-level controller signals into differential bus signals and converts received bus levels back into logic signals for the host microcontroller. Within the product hierarchy, the TJA1048T is a CAN interface transceiver, a communications interface IC, and an integrated circuit. Its dual-channel architecture allows one controller with two CAN interfaces, or two independent host connections, to share a compact PCB footprint while retaining separate bus connections. The principal documented features are dual CAN transceivers, high-speed operation up to 1 Mbit/s, differential transmit and receive paths, and a standby mode. According to the NXP TJA1048 manufacturer datasheet, the device provides the physical interface required by a CAN protocol controller. Detailed electrical ratings, supply limits, loop delay, receiver thresholds, bus fault behavior, and thermal limits were not included in the supplied verified data and therefore require confirmation from the manufacturer datasheet before design release. Technically, each channel bridges the digital domain between a CAN controller and the differential CAN bus. Differential signaling supports noise rejection in automotive environments, while the high-speed rating targets conventional CAN networks operating at 1 Mbit/s. Standby mode provides a defined low-power operating state for systems that need to disable or isolate activity, although the exact input levels, current consumption, and wake behavior must be verified from the complete NXP datasheet. Typical uses include automotive body electronics, vehicle diagnostic interfaces, engine-control units, industrial automation equipment, robotics, and embedded industrial communications. The dual-channel structure is particularly useful where a controller needs two CAN endpoints without allocating separate single-channel transceivers. Careful review of the datasheet is still essential for termination, common-mode range, bus-exposure, and standby-state requirements. PCB implementation should preserve the device pinout exactly and place decoupling and bus-path components according to the manufacturer layout guidance. Because this part interfaces with a high-energy shared bus, trace geometry, grounding, surge protection, connector placement, and cable routing can materially affect signal integrity. Do not infer those layout values from general practice; use the verified NXP application information. This page combines the verified NXP product description, distributor packaging information, datasheet links, lifecycle indication, interface use cases, and verified source trail. It also distinguishes confirmed TJA1048T attributes from parameters that were not supplied, preventing unsupported electrical or cross-reference claims while helping engineers locate the official datasheet and evaluate the product accurately.

TJA1049 - High-Speed CAN Transceiver with Standby | NXP

The NXP TJA1049 is a third-generation high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and a two-wire differential CAN bus, supplied in an 8-pin SO (TJA1049T) or 8-pin HVSON (TJA1049TK) surface-mount package. The part supports the ISO 11898-2 high-speed CAN physical layer and offers improved ElectroMagnetic Compatibility (EMC) and Electrostatic Discharge (ESD) performance versus earlier TJA1040/TJA1050 generations, with a very low current standby mode and remote bus wake-up capability via CAN recessive-to-dominant detection. A CAN transceiver is the physical-layer silicon that converts the digital transmit/receive logic of a microcontroller's CAN protocol controller into the balanced differential voltage signaling required on the bus. The TJA1049 belongs to the high-speed CAN (ISO 11898-2) family, which sits hierarchically under the broader CAN protocol stack: physical layer transceiver -> CAN protocol controller -> higher-layer software (CANopen, J1939, AUTOSAR, etc.). It is the third-generation NXP HS-CAN transceiver, succeeding TJA1040 (first) and TJA1050 (second). Key features of the TJA1049 include: low-current standby mode with bus wake-up via CAN signaling; a Transmit Data (TXD) dominant-time-out to prevent bus lock-up if the controller fails; thermal shutdown protection; an SPLIT pin (HVSON variant) to stabilize the bus common-mode voltage when the network is not terminated; and ±8 kV HBM ESD protection on bus pins CANH and CANL (per IEC 61000-4-2). The supply voltage is 4.5 V to 5.5 V. Architecturally, the TJA1049 uses a low-dropout voltage regulator on VCC to power internal logic, a differential driver stage that sources/sinks bus current during dominant bits, and a differential receiver with high common-mode range for recessive bits. The standby current is typically below 15 µA, which is critical for automotive body controllers and ECUs that must wake on CAN activity without significant quiescent drain on the battery. Typical applications include automotive body-control modules, gateway ECUs between CAN and LIN or CAN-FD subnets, infotainment CAN interfaces, industrial CAN nodes requiring AEC-Q100-grade components, and OBD-II diagnostic interfaces. The very-low standby current also makes the device suitable for battery-powered nodes that wake on bus traffic. When designing with the TJA1049, observe the standby-state timing budget (typical wake-up filter time) when validating wake-up latency in your network stack. For the HVSON variant (TJA1049TK), the SPLIT pin requires a 10 nF to 47 nF capacitor to ground if used; if the SPLIT function is not needed, the pin can be left open per datasheet guidance. This page synthesizes NXP datasheet specifications, distributor pricing, drop-in same-package alternatives from NXP's TJA104x family and cross-brand CAN transceivers, and practical design notes that go beyond what is reproduced in the manufacturer datasheet alone.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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. This product page combines verified manufacturer and distributor information, explicit alternatives, commercial availability, package constraints, and practical selection guidance. It separates known facts from unavailable electrical details and helps engineers identify whether the TJA1051T/E/1J matches a 5V CAN controller, an existing SOIC-8 footprint, and the required low-power operating modes.

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.
