TJA1040T/CM - 1 MBaud CAN Transceiver | NXP
The NXP Semiconductors TJA1040T/CM is a high-speed CAN transceiver rated for operation up to 1 MBaud and supplied in an 8-pin SO package. It provides differential transmit capability to the physical CAN bus and differential receive capability to a CAN protocol controller, making it an interface between controller-area-network logic and vehicle or industrial bus wiring. A CAN transceiver is a physical-layer interface IC within the broader interface-IC hierarchy. It converts the controller’s digital logic signals into differential bus signaling and converts differential bus levels back into logic-compatible receive signals. The TJA1040 is intended primarily for high-speed passenger-car CAN networks, where robust differential signaling, standby control, and electromagnetic compatibility are important. The verified manufacturer information identifies differential transmission, differential reception, high-speed operation up to 1 MBaud, and standby-mode capability as principal device features. The distributor record identifies the TJA1040T/CM,118 ordering form as an 8-pin SO CAN-bus transceiver. Detailed electrical limits, loop-delay values, bus-fault behavior, and package dimensions were not supplied in the verified extract and therefore require confirmation from the manufacturer datasheet before design release. Typical uses include passenger-vehicle body and powertrain CAN networks, automotive control modules, CAN gateways, and industrial equipment that uses a 5 V CAN physical layer. The transceiver is intended to operate with a compatible CAN controller rather than as a standalone bus controller. Its differential bus interface supports robust communication over cable networks, while the standby function can reduce activity when the node is not communicating. Designers should preserve the pin assignment, supply decoupling, CANH/CANL routing, termination, and common-mode protection described by the manufacturer. The verified source set does not include the complete pinout, absolute maximum ratings, thermal data, or EMC test values, so those details must not be inferred. This page combines official NXP information with distributor records and explicitly marks unavailable parameters rather than estimating them. TJA1040T/CM is a legacy EoL-positioned part according to the supplied migration context. For new designs, engineers should compare it with current NXP or third-party CAN transceivers and verify pin, electrical, lifecycle, and qualification compatibility before treating any replacement as drop-in.
TJA1042T/1J - High-Speed CAN Transceiver | NXP | Automotive
The NXP TJA1042T/1J is a high-speed CAN transceiver with standby mode, providing the physical-layer interface between a CAN protocol controller and a differential two-wire CAN bus. The device is packaged as an 8-pin SOIC and is identified by DigiKey as a 1/1 half CAN-bus transceiver. The verified NXP product page describes it as a high-speed CAN transceiver with standby mode, while the manufacturer datasheet states that it supplies differential transmit and receive capability for automotive CAN systems. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into the dominant and recessive voltage levels carried by a CAN bus. It also places the bus-side driver and receiver between the controller and the physical network, helping the controller communicate over a robust multi-node differential bus. The TJA1042 family belongs to the broader CAN transceiver, communication interface, interface IC, and semiconductor hierarchy. The key verified feature set is high-speed CAN operation, differential transmit and receive, standby operation, 8-pin SOIC packaging, and automotive-oriented application positioning. The standby function is useful when a node must reduce activity while retaining the CAN interface. The exact maximum data rate, supply range, loop delay, bus fault behavior, thermal limits, and electrical thresholds are not present in the supplied verified excerpts, so those values must be confirmed from the complete manufacturer datasheet before design release. The TJA1042 is intended for automotive electronic control units, body controllers, powertrain controllers, gateway modules, instrument clusters, and other embedded systems that use a CAN protocol controller. In a typical circuit, the MCU CAN controller connects to TXD and RXD, while CANH and CANL connect to the external bus through the board's approved network interface and termination arrangement. The transceiver is the boundary between digital controller signaling and the differential physical bus. Designers should verify the exact NXP ordering code, supply voltage, transceiver mode timing, bus termination, common-mode environment, loop delay, and external-component recommendations against the complete TJA1042 datasheet. Because the supplied web data does not expose a complete pin-level table, pricing schedule, compliance declaration, or lifecycle statement, those items are marked as needing verification rather than inferred. The TJA1042T/1J is best evaluated by engineers who need a standby-capable, high-speed CAN physical-layer device in an SOIC footprint.
TJA1042T/3/1J - High-Speed CAN Transceiver w/ Standby, SOIC-8 | NXP
The NXP TJA1042T/3/1J is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and a two-wire CAN bus, supplied in an 8-pin SOIC package with a maximum data rate of 1 Mbit/s. It operates from a 4.5 V to 5.5 V VCC supply and supports direct interfacing to microcontrollers with supply voltages as low as 3 V through a dedicated VIO pin (variant /3). The device features low-current Standby mode with bus wake-up capability and ideal passive behavior to the CAN bus when VCC is off. A CAN transceiver (also called a CAN bus transceiver or CAN physical layer device) is a protocol-bridge IC that converts the differential digital signaling on a CAN bus into the single-ended TX/RX logic levels expected by a microcontroller's CAN protocol controller. CAN transceivers sit one layer below the CAN data link layer in the OSI model and are essential for any automotive, industrial, or embedded system that communicates over the Controller Area Network standard (ISO 11898). Without a transceiver the MCU's CAN controller cannot drive or receive the bus. Key features include excellent electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance, an SPLIT-pin-free /3 variant with a VIO reference for 3.3 V MCUs, and pin compatibility with the classic TJA1040, PCA82C250, and PCA82C251. The transceiver supports bus wake-up patterns, thermal shutdown, a dominant time-out that prevents bus lockup if the controller fails, and an unpowered bus node that does not disturb the network. The TJA1042T/3/1J also provides a low-current Standby mode in which the bus is continuously monitored for wake-up frames. Internally the device uses a differential driver with slope control to minimize EMI, very-low-drop receiver comparators, and an integrated VIO reference that allows the logic I/O domain of the chip to match the host MCU's supply. Compared to its predecessor TJA1040, the TJA1042 reduces quiescent current, improves ESD to at least 6 kV HBM, and adds the VIO pin to decouple digital I/O levels from VCC for 3.3 V microcontrollers. Typical applications include automotive body and chassis ECUs, industrial CANopen and DeviceNet nodes, elevator controllers, building automation gateways, and any CAN node that must interface to a 3.3 V microcontroller without level shifters. The part is widely used as the physical-layer upgrade for designs that previously used TJA1040, PCA82C250, or PCA82C251. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin and a 100 nF cap on VIO; add a common-mode choke and split termination (60 ohm + 5.6 nF at each end) on bus lines operating above 500 kbit/s in noisy environments. Tie the STBY pin high for Normal mode and monitor CANH/CANL for short-to-ground or short-to-VCC conditions. The /3 variant replaces the SPLIT pin of the original TJA1042T with a VIO pin, so confirm that the PCB land pattern matches pin 5 = VIO. This page synthesizes distributor pricing, drop-in alternatives from the same TJA1042 family and competitor cross-references such as TCAN1042, plus practical design notes not found in the manufacturer datasheet.
TJA1043T - High-Speed CAN Transceiver, 1Mbps, SO-14 | NXP
The NXP TJA1043T is a high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and a differential two-wire CAN bus, housed in a 14-pin SO (SOIC-14) package. It supports data rates up to 1 Mbps across the ISO 11898-2 / ISO 11898-5 compliant physical layer, and operates from a 5 V supply with very low standby and sleep-mode quiescent currents for ECU sleep-current budgets. The device provides differential transmit and receive capability and integrates dominant-timeout, bus-failure diagnostics, and thermal protection. A CAN transceiver (sometimes called a CAN physical layer or CAN PHY) is the analog interface between a digital CAN protocol controller (typically inside an MCU) and the differential CANH/CANL bus wires that carry data across a vehicle network. It belongs to the broader hierarchy of bus transceivers -> interface ICs -> wired communication ICs. Automotive ECUs (Electronic Control Units) require a certified transceiver that meets ISO 11898 EMC and ESD specifications; the TJA1043 family is a third-generation NXP design widely used in body, chassis, and powertrain CAN nodes. Key features include 1 Mbps maximum bit rate, ±8 kV HBM ESD on bus pins (per NXP datasheet figures), very low quiescent current in Sleep mode (typically a few microamps), an SPLIT pin for bus biasing when the bus is off, and three operating modes (Normal, Standby, Sleep) selectable via the EN and STBN pins. The IC operates across -40 °C to +125 °C ambient and is qualified to the automotive quality flow. Internally the TJA1043T uses a bipolar-CMOS-DMOS (BCD) process that combines 5 V analog drive strength on the bus with low-power digital logic. The receiver includes a wide common-mode range for excellent EMC immunity, and the transmitter incorporates slew-rate control to limit EMI on unshielded bus segments. Typical applications include automotive body control modules, gateway ECUs, chassis controllers, infotainment CAN nodes, and industrial CAN-FD ready nodes that need backward-compatible high-speed CAN. The wide common-mode range also makes it suitable for 12 V and 24 V battery systems in trucks and off-road equipment. When designing with this part, place a 100 nF decoupling capacitor close to VCC and respect the SPLIT-pin biasing network shown in the datasheet typical application. Verify bus termination (120 Ω at each end) and dominant-timeout behaviour when using a permanently dominant TXD input. This page synthesizes distributor pricing, drop-in alternative guidance, and practical design notes that complement the manufacturer datasheet and accelerate your component selection.
TJA1043T-1J - High-Speed CAN Transceiver, 5Mbit/s | NXP
The NXP TJA1043T-1J is a third-generation high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and a differential two-wire CAN bus, supporting data rates up to 5 Mbit/s in a 14-pin SOIC package. It features VIO supply pin for direct interfacing with 3.3V microcontrollers, SPLIT voltage output for bus biasing stabilization, dedicated wake-up input, standby control (STBN), and an enable pin. The part is qualified for automotive networks and conforms to ISO 11898-2:2024 high-speed CAN physical layer requirements. A CAN transceiver is an interface IC that translates single-ended logic-level TXD/RXD signals from a microcontroller into the differential voltage signaling required on the CANH and CANL bus wires, while simultaneously protecting the controller from bus-side ESD and EMC events. Within the broader hierarchy, the TJA1043 belongs to the class of bus transceivers (also called physical-layer devices or PHYs), which sit between the data-link-layer CAN controller and the physical CAN bus medium in an in-vehicle network. Key features include very low quiescent current consumption in standby and sleep modes, passive bus behavior when supply is off (no reverse current into the bus), integrated thermal shutdown, and bus-pin ESD protection up to ±8 kV HBM. The VIO pin allows the logic supply to be tied directly to a 3.3V microcontroller without level shifters, simplifying mixed-voltage ECU designs. Typical applications include automotive body and powertrain ECUs, gateway modules, ADAS sensor nodes, industrial CAN automation networks, and CAN-FD backbone segments where bus termination biasing and EMC robustness are critical. The SPLIT pin stabilizes the recessive bus common-mode voltage, especially important in networks with multiple unpowered nodes. When designing with this device, keep the SPLIT pin terminated through a capacitor to ground per the datasheet reference design, and ensure the VIO and VCC rails are sequenced correctly to avoid latch-up during cold-crank events in 12V automotive systems.
TJA1043TK - High-Speed CAN Transceiver, HVSON-14 | NXP
The NXP TJA1043TK is a third-generation high-speed Controller Area Network (CAN) transceiver that provides the physical-layer interface between a CAN protocol controller and a two-wire differential CAN bus, housed in a 14-pin HVSON (3.0 mm x 4.5 mm) package. It supports data rates up to 1 Mbit/s, an operating supply range of 4.75 V to 5.25 V on VCC, and an I/O supply (VIO) of 2.8 V to 5.25 V for direct interfacing with 3.3 V and 5 V microcontrollers without level shifters. The device offers very low quiescent current in standby (~10 uA typical) and sleep (~10 uA typical) modes, making it well suited to permanently powered automotive ECUs that must respect <100 uA quiescent budgets. A Controller Area Network transceiver is the physical-layer bridge inside automotive and industrial networks that converts the digital transmit/receive signals of a microcontroller-side CAN controller into the differential voltages (dominant and recessive bus states) required by the ISO 11898-2/-5 CAN standard. It is the physical interface IC in the broader hierarchy: transceiver -> CAN interface -> automotive network IC -> semiconductor, with the TJA1043TK sitting alongside similar devices such as the NXP TJA1042, TJA1051, and the TI TCAN1043 series. Key features include an integrated low-dropout regulator (LDO) that powers the bus-side circuitry from the battery rail, advanced EMC/ESD performance compliant with IEC 61000-4-2 and IEC 61967-4 automotive EMI requirements, bus pins tolerant to -27 V to +40 V (CANH/CANL), and support for local and remote wake-up with wake-up source recognition via the WK and WUP outputs. Functional modes - Normal, Standby, Sleep, Go-To-Sleep, and Power-On - are managed through the EN, STBN, and VBAT pins, allowing deterministic node power management across the vehicle network. Typical applications include automotive body-control modules (BCMs), gateway ECUs, infotainment domain controllers, powertrain ECUs, industrial CANopen networks, and telematics control units. The device supports both 12 V and 24 V battery systems, satisfying automotive OEM requirements for cold-crank and load-dump transients defined by ISO 7637-2. When designing with this part, keep the bus termination (typically 120 ohm split termination with common-mode capacitors) close to the CANH/CANL pins, and route the bus traces as a matched 100 ohm differential pair on the inner PCB layers. Use a 100 nF ceramic decoupling capacitor on VCC and VIO placed within 2 mm of the respective pins. The VIO pin allows direct 3.3 V logic connection, eliminating the need for an external level shifter on most modern 32-bit microcontrollers.
TJA1043TK/1Y - High-Speed CAN Transceiver, 1Mbps, 14-HVSON | NXP
The NXP TJA1043TK/1Y is a high-speed Controller Area Network (CAN) transceiver providing an interface between a CAN protocol controller and the physical two-wire CAN bus, supporting data rates up to 1 Mbps in a 14-pin HVSON (3x4.5 mm) package. It operates from a 4.5V to 5.5V supply, includes power-down, standby, and sleep modes, and features a low-power standby mode with bus wake-up capability for ISO 11898-5 compliant networks. A CAN transceiver is a physical-layer interface IC that converts the digital transmit (TXD) and receive (RXD) signals from a CAN protocol controller into the differential CANH/CANL bus voltages defined by ISO 11898-2, while also providing ESD protection and common-mode rejection. As a category, CAN transceivers sit below CAN protocol controllers in the in-vehicle networking (IVN) hierarchy and are essential building blocks for CAN, CAN FD, and partial networking systems in automotive body, chassis, and powertrain ECUs. The TJA1043TK/1Y integrates diagnostic features including bus failure detection (open, short to battery, short to VCC, and CANH/CANL short) and supplies a SPLIT output that stabilizes recessive bus voltage when the bus is DC-loaded. It offers ±8 kV ESD contact discharge on the bus pins per IEC 61000-4-2 and is qualified per AEC-Q100 Grade 1 for automotive environments. The HVSON-14 package with exposed pad provides low thermal resistance, suitable for under-hood and body-control module placements. The architecture is based on a bipolar-CMOS-DMOS (BCD) process, combining low standby current (typ. <15 uA in sleep mode) with high bus-driver output swing. Integrated non-volatile trimming of bus dominant/recessive thresholds ensures bit-timing symmetry for high-speed CAN networks up to 1 Mbps. Typical applications include automotive body control modules, gateway ECUs, powertrain controllers, chassis electronics, and CAN gateways. It is also used in industrial CAN networks, agricultural machinery CAN buses, and in heavy-duty vehicle multiplexing systems where AEC-Q100 reliability is required. When designing with the TJA1043TK/1Y, place the VBAT/5V supply decoupling capacitor (typically 100 nF) within 2 mm of the VCC pin and ensure the exposed pad is soldered to a continuous ground copper plane for thermal dissipation. For low-EMI operation, the SPLIT pin must be biased through a 10 nF capacitor. This page synthesizes distributor pricing (as of 2026-10-11), drop-in alternatives sourced from the NXP TJA1043 family, and practical design notes not found in the manufacturer short datasheet.
TJA1043TKY - 5 Mbps CAN Transceiver | NXP | Automotive
NXP Semiconductors TJA1043TKY is a high-speed CAN transceiver for automotive networking, providing one CANbus transceiver with differential transmit and receive capability for a protocol controller. The verified distributor data identifies a maximum data rate of 5 Mbps, a 5 V supply, normal, sleep, and standby operating modes, AEC-Q100 qualification, and a 14-pin HVSON package measuring 3 x 4.5 mm. It interfaces a Controller Area Network protocol controller with the physical two-wire CAN bus. A Controller Area Network transceiver is a physical-layer interface within the CAN network hierarchy. A CAN protocol controller generates and interprets framed messages, while the transceiver converts those digital controller signals into differential bus levels and converts received bus levels back into controller-compatible signals. This division keeps protocol handling and physical-layer signaling separate, allowing a microcontroller-based CAN controller to communicate over a differential, fault-tolerant vehicle network. The TJA1043TKY supports high-speed CAN communication up to 5 Mbps and includes standby and sleep modes for reduced power use when communication is not continuously required. Normal mode supports active bus communication, while the low-power modes help manage operating current in parked or partially active vehicle systems. The part is identified by distributor listings as automotive-grade and AEC-Q100 qualified. Its small HVSON package supports compact electronic control-unit layouts, although exposed-pad layout and thermal management must follow the NXP datasheet. The transceiver provides the required interface between a CAN protocol controller and the physical two-wire CAN bus. Differential signaling improves common-mode rejection on vehicle networks, while the transceiver handles the electrical relationship between controller-side TXD and RXD signals and bus-side CANH and CANL conductors. Because these signals interact with wiring, termination, protection, and electromagnetic compatibility requirements, PCB layout and cable routing remain as important as controller firmware. Typical uses include automotive body-control modules, powertrain controllers, gateway units, comfort systems, engine controllers, and industrial CAN equipment connected to vehicle-grade electronics. The verified data specifically associates the device with 5 Mbps CAN, 5 V operation, low-power sleep and standby states, and automotive qualification. It is suitable when an existing design uses the 14-HVSON footprint and its exact pin functions and exposed-pad requirements. A critical design step is to reproduce the manufacturer-recommended package land pattern, pin assignments, CAN bus routing, termination, and decoupling exactly from the datasheet. Do not infer exposed-pad connections or bus-component values from the distributor summaries. Before release, validate timing, bus loading, fault behavior, sleep current, EMC performance, and wake behavior across temperature and supply tolerances using the complete manufacturer documentation. This page combines verified distributor specifications, official NXP documentation, application guidance, and drop-in-replacement constraints. It also identifies where detailed pin-level, electrical-limit, lifecycle, price, and certification information requires direct verification from the manufacturer datasheet or current distributor quotation.
TJA1044GT - High-Speed CAN Transceiver, SO-8 | NXP
The NXP Semiconductors TJA1044GT is a high-speed Controller Area Network (CAN) transceiver with Standby mode, providing the physical interface between a CAN protocol controller and the differential two-wire CAN bus. It is housed in an 8-pin SO (SOIC-8) package, supports data rates up to 5 Mbps for CAN FD, and is qualified to AEC-Q100 Grade 1 for automotive body and safety applications. A CAN transceiver is a physical-layer (PHY) device that translates the digital transmit/receive logic signals from a microcontroller or CAN protocol controller into the differential voltage levels defined by ISO 11898-1 for the CAN bus. Within the broader hierarchy, a CAN transceiver sits between the data-link layer (handled by the protocol controller) and the physical differential bus; in an in-vehicle networking stack it is part of the in-vehicle communication (IVN) physical layer alongside LIN, FlexRay and Ethernet PHYs. Key features include very low standby current (typical 5 uA) for always-on automotive networks, an autonomous standby/sleep mode that wakes the device when bus activity is detected, excellent EMC performance optimized for automotive bus nodes, and full ISO 11898-2 (and ISO 11898-5 for the low-power variant) compliance. The Mantis family architecture used across the TJA1044 family provides tight parametric matching between variants, simplifying multi-rail ECU designs. The TJA1044GT is part of NXP's Mantis CAN transceiver family and is widely used as a drop-in replacement or alternate for the legacy TJA1050/TJA1040 in next-generation ECUs. The 8-pin SO (SOIC-8) footprint with industry-standard pinout (TXD, GND, VCC, RXD, VIO/n.c., CANH, CANL, STB) allows easy migration from older TJA1040/TJA1050 designs to modern CAN FD networks. The part operates from a single 4.75V to 5.25V supply on VCC. Typical applications include automotive body-control modules (BCMs), gateway ECUs, infotainment and cluster CAN nodes, chassis and powertrain CAN nodes requiring low quiescent current, and industrial CAN networks. The selective wake-up capability also suits CAN-based partial networking where the ECU must remain in low-power while monitoring the bus for a wake frame. When designing with the TJA1044GT, place a 100 nF decoupling capacitor close to VCC (pin 5 on the GT variant, which has no VIO pin) and ensure the split-termination (typically 60 ohm with two 30 ohm resistors and a 4.7 nF capacitor to ground) is correctly placed for proper recessive-level biasing. The STB pin must be tied to logic-low for Normal operation. This page synthesizes distributor stock and pricing, drop-in TJA1044 family alternatives, and practical EMC/PCB layout notes that are not compiled in a single place in the manufacturer datasheet.
TJA1044GT-3Z - High-Speed CAN Transceiver with Standby Mode | NXP
The NXP TJA1044GT-3Z is a high-speed Controller Area Network (CAN) transceiver with Standby mode, housed in an 8-pin SO (SOIC-8) package, designed to interface a CAN protocol controller with the physical two-wire CAN bus. It belongs to the Mantis family of high-speed CAN transceivers from NXP Semiconductors, providing differential transmit and receive capability between a microcontroller and the CAN bus. The device operates from a 4.75V to 51V supply range and supports data rates up to 1 Mbit/s per ISO 11898-2, including CAN FD (Flexible Data-rate) frames in the arbitration phase. A CAN transceiver is a physical-layer (PHY) interface IC that bridges the digital logic domain of a CAN protocol controller (typically embedded in a microcontroller) and the differential voltage-domain wire bus. In the broader IC hierarchy, a CAN transceiver belongs to the Interface IC category, which also includes LIN transceivers, RS-485/RS-232 transceivers, and I2C/SMBus repeaters; together these form the connectivity layer of an automotive or industrial electronic control unit (ECU). The TJA1044GT-3Z additionally integrates an autonomous standby mode and a STB pin for selective wake-up, enabling low-quiescent-current operation in always-on automotive body-network ECUs. Key features of the TJA1044GT-3Z include ultra-low power consumption in standby mode, very low electromagnetic emission (EME), high electromagnetic immunity (EMI), and integrated TXD dominant-timeout protection. According to the manufacturer datasheet, the transceiver is designed for high-speed CAN applications in the automotive industry and provides differential transmit and receive capability between a microcontroller and a CAN bus. It supports both 3.3 V and 5 V microcontrollers when used in the proper VIO configuration (variant -3 has the VIO supply pin). The TJA1044GT-3Z uses a bipolar process with integrated ESD protection on the bus pins (typically ±8 kV HBM, ±6 kV IEC 61000-4-2 contact discharge per the datasheet). The architecture separates the transmit data path (TXD) from the receive data path (RXD) and includes slope control to limit the slew rate of the CANH/CANL edges, reducing radio-frequency emissions. The standby mode reduces current consumption dramatically so the ECU can satisfy automotive quiescent-current budgets when the ignition is off but the network must remain wake-capable. Typical applications include automotive body and comfort networks (door modules, seat controllers, mirror modules), powertrain ECUs (where CAN FD is required for sensor aggregation), chassis and safety CAN nodes, industrial CAN gateways, and CAN-bus diagnostic interfaces. The wide supply range (down to 4.75 V and tolerant to load-dump events up to 51 V) makes the TJA1044 directly compatible with 12 V automotive battery rails without external protection components. When designing with the TJA1044GT-3Z, place a 100 nF decoupling capacitor on VCC as close as possible to the pin, and follow the datasheet's recommendations on CAN bus termination (typically 120 ohm at each end of the bus). Do not leave the STB pin floating; tie it to GND for normal operation or to the microcontroller for wake/sleep control. Always respect the maximum bus voltage rating, especially in 24 V truck systems where the load-dump transient can exceed 51 V if the suppression is inadequate. This content combines datasheet values, cross-reference data, and practical design guidance not collated on any single distributor page.
TJA1044GTJ - 5Mbps CAN Transceiver, 8-SOIC | NXP
The NXP Semiconductors TJA1044GTJ is a high-speed CAN transceiver with standby mode, providing one transmitter and one receiver for a two-wire Controller Area Network bus. It supports a data rate of 5 Mbps and a 4.75 V to 5.25 V supply range in an 8-pin SOIC surface-mount package. The transceiver includes a 300 mV receiver hysteresis and is intended to connect a CAN protocol controller to the physical CAN network. A CAN transceiver is the physical-layer interface within a Controller Area Network system. The protocol controller creates and interprets CAN frames, while the transceiver converts those digital signals into differential bus levels and converts received bus levels back into controller-compatible logic. CAN transceivers therefore belong to the hierarchy of interface IC, communications transceiver, CAN interface, and semiconductor. Verified device data identifies the TJA1044GTJ as a one-driver, one-receiver, half-duplex 5 Mbps CAN interface with standby mode. Its 8-SOIC package supports automated surface-mount assembly, while the 300 mV receiver hysteresis provides noise margin around the receiver switching threshold. The 4.75 V to 5.25 V supply range permits use with conventional regulated 5 V digital systems. The TJA1044 belongs to NXP's Mantis high-speed CAN transceiver family and targets automotive networking. Its CANH and CANL bus-side interface must operate with the protection, termination, routing, and common-mode strategy required by the target vehicle network. Standby mode provides a means to reduce participation when the node does not require normal bus operation, but the system designer must confirm all wake-up behavior from the complete manufacturer documentation. Typical uses include body-control modules, automotive comfort systems, powertrain-adjacent controllers, gateway nodes, and industrial CAN equipment connected to 5 V logic. A CAN controller, crystal or clock source, decoupling network, bus termination, and connector are normally placed around the transceiver according to the reference design and system requirements. Design care should focus on bus-layout symmetry, short ground returns, correct split termination, compliant common-mode protection, and validation of standby-state timing. The CAN wires should not be routed as ordinary unprotected low-speed signals because fast edges and faults can exceed expectations outside the transceiver operating envelope. This page consolidates verified manufacturer and distributor information, separates known TJA1044GTJ characteristics from missing data, and evaluates candidate replacements conservatively. It is intended to add sourcing context and design guidance without presenting unsupported electrical limits or unverified cross-brand pin compatibility as fact.
TJA1044GTKZ - High-Speed CAN Transceiver, 5Mbps, HVSON-8 | NXP
The NXP TJA1044GTKZ is a high-speed Controller Area Network (CAN) transceiver from the Mantis family, providing the physical interface between a CAN protocol controller and the two-wire CAN bus, packaged in an 8-pin HVSON (3mm x 3mm) with an exposed thermal pad. It supports data rates up to 5 Mbps in CAN FD (Flexible Data-rate) networks and features a low-power Standby mode for quiescent current reduction when the bus is idle. A CAN transceiver is a physical-layer device that converts the digital transmit/receive signals of a CAN controller into the differential voltage levels required by the CAN bus standard (ISO 11898-2:2016). As a member of the high-speed CAN transceiver category, the TJA1044 sits at the bottom of the in-vehicle networking hierarchy: microcontroller -> CAN controller (typically integrated in the MCU) -> CAN transceiver (TJA1044) -> differential CAN bus. It is foundational to automotive and industrial communication networks where reliable, deterministic messaging is critical. Key features include a very low-current Standby mode with remote wake-up via a wake-up pattern (WUP) recognition per ISO 11898-2:2016, bus-fault detection and protection against -27 V to +40 V automotive transients, thermal shutdown, and an undervoltage detector on VCC and VIO. The transceiver operates from a single 5 V supply (VCC), with a separate VIO pin for direct interfacing to 3.3 V or 5 V microcontrollers without level shifters. The TJA1044 uses a fully ISO 11898-2:2016 compliant driver and receiver with dominant-timeout protection to prevent a faulty controller from permanently clamping the bus. The integrated slope-control function (via the STB/NRM pin) and low Electromagnetic Emission (EME) design simplify EMC compliance in dense automotive modules. The exposed thermal pad (EP) of the HVSON-8 package is essential for dissipating heat during sustained dominant transmission, ensuring reliable operation across the -40 C to +150 C automotive Grade-1 temperature range. Typical applications include body control modules, gateway ECUs, powertrain ECUs, battery management systems (BMS), ADAS sensor ECUs, industrial CAN nodes, and telematics control units. Its 5 Mbps capability makes it suitable for CAN FD networks carrying larger payload data, while Standby mode enables CAN partial networking for ECUs that must wake only on recognized WUP messages. When designing with the TJA1044, terminate the bus with a 120 ohm split-terminator network (RT = 60 ohm + 60 ohm + 4.7 nF common-mode cap) rather than a single 120 ohm resistor, which improves EMI/ESD immunity and DC stability. Place a 100 nF decoupling capacitor close to VCC and ensure the exposed pad is soldered to a sufficient copper pour for thermal dissipation.

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.
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
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 - 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.

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/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.
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.
