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.

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.

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.

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. This page synthesizes distributor pricing, drop-in alternatives from NXP and TI, and practical design notes not found in the manufacturer datasheet.
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.
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.
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.

TJA1052IT-5Y - Isolated High-Speed CAN Transceiver 5Mbps AEC-Q100 | NXP
The NXP TJA1052IT-5Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver that provides a 5 Mbps interface between a CAN protocol controller and the physical two-wire CAN bus, housed in a 16-pin SOIC package with 5 kV RMS isolation. It targets Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), and any application requiring reinforced isolation between bus nodes. The integrated digital isolator and CAN transceiver in one package eliminates the need for a discrete isolator plus discrete transceiver, cutting board area roughly in half and simplifying EMC design. A CAN transceiver is a physical-layer (PHY) device that converts differential CAN logic levels from a microcontroller's CAN controller into the dominant/recessive bus signaling required by ISO 11898-2, while providing bus-side fault protection and EMC robustness. The TJA1052IT specifically adds on-chip galvanic isolation - replacing a two-chip solution (isolator + CAN transceiver) with a single device - and is part of the broader hierarchy: CAN transceiver -> interface IC -> integrated circuit. Key features include data rates up to 5 Mbps (CAN FD capable), an isolation voltage of 5000 V RMS for 1 minute per UL 1577, bus fault protection from -27V to +40V, an operating supply range that supports both 1.8V/3.3V/5V MCU sides, and AEC-Q100 qualification for automotive environments. A low-power standby mode with bus wake-up detection is also present, achieved through a dedicated STBY pin and a remote wake-up pattern recognizer compliant with ISO 11898-5. The TJA1052IT uses NXP's integrated capacitive-coupled isolation technology plus a proven CAN PHY, achieving low loop delay under 200 ns - critical for CAN FD frames at the maximum payload phase. Compared with discrete optocoupler + CAN transceiver solutions, the integrated approach reduces propagation delay variation over temperature by a factor of 2-3, improving timing margin in large or noisy automotive networks. Typical applications include EV/HEV battery management system (BMS) bus isolation, OBC (on-board charger) to VCU communication, industrial CAN bus nodes requiring 5 kV isolation (solar inverters, motor drives), EV charging stations with isolated CAN, isolated industrial sensor hubs, and automotive ECU-to-ECU isolation. A key design consideration is the supply topology: the device has two VCC rails - VCC1 (logic/microcontroller side, 2.5V-5.5V) and VCC2 (bus-side, 4.5V-5.5V) - each requiring local decoupling. Designers should follow NXP application note AN11253 for PCB layout, especially maintaining a creepage/clearance margin under the isolation barrier. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, including structured comparison with the TI ISO1042DW as identified in NXP community threads.
TJA1052IT/2Y - Isolated High-Speed CAN Transceiver | NXP
The NXP TJA1052IT/2Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver that provides a 2.5 kVrms isolated interface between a CAN protocol controller and the physical two-wire CAN bus, housed in a 16-pin SO (SOIC-16, 300 mil) package with capacitive (galvanic) isolation integrated on-chip. The device operates from a 3 V to 5.25 V supply on the logic/microcontroller side and supports a CAN data rate of up to 5 Mbps, making it suitable for Classic CAN and CAN FD frame formats. The integrated isolation removes the need for an external digital isolator + isolated DC-DC combination in many designs, reducing BOM count and PCB area. What is an isolated CAN transceiver? A CAN transceiver is the physical-layer bridge between a CAN controller (typically embedded in a microcontroller) and the differential CAN bus lines (CANH/CANL). A galvanically isolated version inserts a high-voltage barrier - here implemented via on-chip capacitive coupling - between the logic domain and the bus domain, breaking ground loops and protecting low-voltage MCU I/O from high-voltage transients common in automotive 12 V/24 V powertrain systems and industrial installations. Key features of the TJA1052IT/2Y include 1/1 unidirectional channel count, 2.5 kVrms isolation voltage rating, 5 Mbps maximum data rate, a standby mode for low quiescent current, and compatibility with 1.8 V and 3.3 V controller logic via separate VIO/VCC rails. The device is specifically targeted at Electric Vehicles (EV), Hybrid Electric Vehicles (HEV), and other automotive applications where high-speed CAN communication must coexist with high-voltage battery and inverter systems. Typical applications include EV/HEV battery management system (BMS) communication gateways, on-board chargers (OBC), traction inverter CAN interfaces, industrial CAN bus nodes requiring reinforced insulation, and isolated debug or service interfaces for automotive ECUs. When designing with the TJA1052IT/2Y, engineers should provide local decoupling on both the logic-side and bus-side supplies, observe creepage/clearance for the 2.5 kV isolation barrier, and verify the standby-mode behavior against the system power-state diagram.

TJA1057BTK - High-Speed CAN Transceiver | NXP Semiconductors
The NXP Semiconductors TJA1057BTK is a high-speed Controller Area Network (CAN) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus in an 8-pin HVSON (3x3 mm) package with exposed pad. It supports data rates up to 5 Mbps (CAN FD capable), operates over a wide supply range of 4.75 V to 5.25 V, and is designed for high-speed CAN applications in the automotive industry. A CAN transceiver (also called a CAN bus driver/receiver) is a physical-layer IC that converts the differential digital signaling of a CAN protocol controller into the differential voltage levels required by the ISO 11898-2 CAN bus standard. It sits between a microcontroller's CAN module and the bus wires (CANH/CANL), providing immunity to common-mode noise and ESD protection. CAN transceivers belong to the broader family of interface ICs and are essential building blocks for in-vehicle networking, industrial automation, and any distributed control system that uses the CAN protocol. The TJA1057BTK delivers differential transmit capability to the bus with controlled slew rate, and differential receive capability with high common-mode rejection. It supports both Normal and Silent operating modes, where Silent mode disables the transmitter for listen-only diagnostics. The device is optimized for low electromagnetic emission (EME) and high electromagnetic immunity (EMI), meeting the stringent automotive requirements for CAN bus communication. Integrated thermal protection, bus dominant time-out, and under-voltage detection on VCC enhance system reliability. The 8-pin HVSON package (3x3 mm) with exposed thermal pad offers a very compact footprint suitable for space-constrained ECUs (Electronic Control Units). The exposed pad provides a low thermal resistance path to the PCB copper, allowing the IC to handle the bus fault conditions specified in ISO 11898-5 without derating. The TJA1057BTK is functionally identical to the TJA1057CT within the SOI3+ process family - they differ only in the VIO supply pin logic level handling. Typical applications include automotive body and comfort ECUs, infotainment CAN interfaces, industrial CAN nodes, building automation, and any embedded system requiring a robust, standardized CAN physical layer. In these use cases, the TJA1057BTK acts as the bus interface between a 3.3 V or 5 V microcontroller's CAN controller and the 12 V automotive CAN bus. A key design consideration is the bus termination: a 120 Ω resistor (or split 60 Ω + 60 Ω with capacitor) must be present at each end of the CAN bus segment. The HVSON exposed pad must be soldered to a copper pad of at least 1 mm² to ensure proper thermal performance under continuous bus fault conditions. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet. The information gain comes from a structured cross-reference analysis combining the TJA1057 datasheet family, the obsolescence brief on TJA1050 replacements, and verified distributor stock data as of 2026-10-16.
TJA1057BTK-0J - 5Mbps CAN FD Transceiver, HVSON-8 | NXP
The NXP TJA1057BTK-0J is a high-speed CAN (Controller Area Network) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus. Housed in an 8-pin HVSON (3x3 mm) package with exposed pad, it supports data rates up to 5 Mbps and is qualified to AEC-Q100 Grade 1 for automotive applications. A CAN transceiver (also called a CAN bus transceiver or CAN interface IC) is a physical-layer device that converts the digital transmit/receive logic signals of a CAN protocol controller inside a microcontroller into the differential CANH/CANL bus signals required on the actual network. CAN belongs to the broader category of serial communication interface ICs, alongside RS-485, RS-232 and LIN transceivers. The TJA1057 family specifically targets high-speed classical CAN and CAN FD (Flexible Data-rate) networks used for powertrain, chassis and body electronics. Key features include a low electromagnetic emission (EME) common-mode choke design, high electromagnetic immunity (EMS), a low-power Standby mode with remote wake-up capability, and ±8 kV HBM ESD protection on the bus pins (per IEC 61000-4-2 on the bus pins, per datasheet). The transceiver operates from a 4.5 V to 5.5 V VCC supply, supports bus voltages from -27 V to +40 V, and provides a TxD dominant time-out for fail-safe behavior. The TJA1057BTK/0J variant carries the 'B' suffix (VIO supply pin present, allowing direct level-shifting to MCUs at 3.3 V or 5 V) and the 'TK' suffix indicating the 8-pin HVSON package with exposed pad. The /0J suffix designates the production ordering code (tape-and-reel packaging). Internally, the device uses a silicon-on-insulator (SOI) process (NXP SOI3+ family), which gives it excellent ESD and latch-up immunity versus older bulk-silicon CAN transceivers like the TJA1050. Typical applications include automotive body control modules (BCMs), gateway ECUs, instrument clusters, HVAC control units, transmission ECUs and industrial CAN nodes operating up to 1 Mbit/s in classical CAN or 5 Mbps in CAN FD networks. The transceiver interfaces directly to NXP S32K and most third-party automotive MCUs. When designing with this part, place the VCC decoupling capacitor (typically 100 nF) directly adjacent to pin 8 and connect the exposed pad (pin 0) to a large PCB ground plane for thermal dissipation and low-impedance return paths. Match the CANH/CANL bus termination to 120 Ω at the network ends to satisfy ISO 11898-2 and avoid signal-integrity issues at high bus loads.
TJA1057GT/1Z - High-Speed CAN Transceiver SOIC-8 | NXP
The NXP TJA1057GT/1Z is a high-speed CAN (Controller Area Network) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus, housed in an 8-pin SOIC (SO-8) package. Key specifications include ISO 11898-2:2016 conformance, data rates up to 1 Mbit/s on the TJA1057T variant with CAN FD support on other variants, and automotive-grade temperature operation. What is a CAN transceiver? A CAN transceiver is a physical-layer interface IC that converts digital transmit/receive logic signals from a microcontroller CAN controller into differential voltage signals on a two-wire CAN bus (CANH and CANL). It belongs to the hierarchy: CAN transceiver -> CAN interface IC -> Interface ICs -> Integrated Circuits. The transceiver also provides bus protection, fault tolerance (dominant/recessive clamping, TXD dominant time-out), and EMC/ESD robustness required in automotive environments. Key features of the TJA1057 include very low current consumption in standby and go-to-sleep modes with remote wake-up capability, an integrated VIO supply pin on /3 variants for direct interfacing with 3.3V and 5V microcontrollers, and an undervoltage detection on VCC and VIO supplies. The TJA1057 implements the CAN physical layer per ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, with the TJA1057T explicitly specified for data rates up to 1 Mbit/s. Architecturally, the device uses a differential transmit/receive path with slope control for low-EMI operation, an internal LDO for digital supply, and a sophisticated thermal protection scheme. Its split-pin output stage balances common-mode stability with low electromagnetic emissions, making it well-suited for automotive body, chassis, and powertrain networks. Typical applications include automotive body control modules, gateway ECUs, infotainment CAN nodes, industrial CAN automation nodes, and CAN-FD enabled instrument clusters. Its robustness against ESD (>6 kV HBM) and bus fault voltages (±58 V) makes it dependable in harsh electrical environments. When designing with this device, ensure proper bus termination with 120 ohm resistors at each end of the bus and a common-mode choke for EMI-sensitive applications. The TJA1057 requires careful placement of the VCC decoupling capacitor close to pin 1 to maintain supply stability during dominant-to-recessive transitions.

TJA1057GTJ - High-Speed CAN Transceiver, 1Mbps, 8-SO | NXP
The NXP Semiconductors TJA1057GTJ is a high-speed Controller Area Network (CAN) transceiver in the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus, delivered in an 8-pin SO (SOIC-8) surface-mount package. It supports data rates up to 1 Mbit/s, operates from a 4.75 V to 5.25 V supply, and is qualified for the -40 °C to +150 °C automotive temperature range. The TJA1057GTJ integrates differential transmit/receive capability, standby mode, and superior EMC and ESD performance versus earlier-generation transceivers. A CAN transceiver is the physical-layer (PHY) bridge between a digital CAN protocol controller (typically integrated into a microcontroller) and the differential CAN bus wiring in a vehicle or industrial network. Transceivers convert the controller's TX/RX logic-level signals into the ISO 11898-2 compliant differential bus levels, and they protect the controller from bus-level transients. The TJA1057GTJ belongs to NXP's Mantis family, which improved on the predecessor TJA1051/TJA1042 series by offering lower electromagnetic emissions and higher ESD robustness while maintaining pin compatibility. Key specifications include: 1 Mbit/s maximum data rate, 4.75 V to 5.25 V supply range, low-current standby mode, ISO 11898-2 conformance, bus pin ESD robustness of ±8 kV HBM (typical), and integrated thermal protection. The device is optimized for 12 V automotive systems and supports both normal and standby operation modes. The SOIC-8 package offers a standard 3.9 mm body width suitable for reflow soldering in automotive PCB assemblies. Architecturally, the TJA1057 uses a silicon-on-insulator process node that allows the bus pins (CANH, CANL) to survive load-dump transients up to ±42 V typical without external protection, while maintaining low quiescent current in standby mode. The device includes slope control for reduced EMI, dominant-timeout protection, and a bus-dominant detection feature that prevents the controller from being locked in a dominant state if a wiring fault occurs. Typical applications include automotive body and powertrain CAN nodes, industrial CANopen networks, gateway ECUs, and any 5 V microcontroller-based system requiring an ISO 11898-2 compliant physical layer. It is widely used in BMS modules, HVAC controllers, instrument clusters, and ADAS sensor nodes where reliable high-speed differential communication is required. When designing with the TJA1057GTJ, place a 100 nF decoupling capacitor close to pin 8 (VCC) and respect the bus termination scheme (typically 120 Ω at each end of the CAN bus segment). The standby pin (STB) should be tied to GND through a pull-down or controlled by the host MCU; a high level puts the part into low-power standby with the bus monitor still functional.

TJA1057GTK - High-Speed CAN Transceiver, 1 Mbit/s, 8-HVSON | NXP
The NXP TJA1057GTK 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 a compact 8-pin HVSON (3x3 mm) package with an exposed thermal pad. It supports data rates up to 1 Mbit/s, operates from a 4.75V to 5.25V supply, and delivers differential transmit/receive capability required by automotive in-vehicle networks. The TJA1057GTK variant includes a standby mode for low-power operation and is optimized for superior electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance. A CAN transceiver is a physical-layer interface IC that converts the digital transmit (TXD) and receive (RXD) signals from a CAN controller into the differential CANH and CANL bus voltages defined by the ISO 11898-2 standard. Within the broader hierarchy, a CAN transceiver sits below the CAN controller (typically inside a microcontroller) in the Open Systems Interconnection (OSI) model and sits above the physical bus medium. Without a transceiver, a controller cannot meet the bus-level timing, drive strength, or fault protection that an automotive CAN bus demands. Key features include a low-current standby mode with remote wake-up via bus activity, thermal protection, bus-dominant time-out to prevent a stuck node from blocking the bus, and an undervoltage detection on the VCC supply. The HVSON-8 package features an exposed thermal pad that reduces junction-to-ambient thermal resistance, enabling AEC-Q100-qualified automotive operation across the -40C to +125C range. The TJA1057 is pin-compatible with the legacy TJA1050 footprint in SO-8 but uses the smaller, thermally enhanced HVSON-8 package in this GTK suffix variant. The transceiver uses a symmetric differential driver stage that minimizes electromagnetic emissions, and the receiver incorporates a wide common-mode range to tolerate ground shifts between nodes on long bus runs. An integrated slope-control resistor optimizes the rise/fall times of the CANH/CANL edges to balance emissions against bit-timing symmetry. Typical applications include automotive body control modules, gateway ECUs, infotainment CAN interfaces, industrial CANopen networks, and any 12V/24V automotive subsystem that communicates via CAN at speeds from 10 kbit/s to 1 Mbit/s. Designers select the TJA1057GTK when EMC performance and a small PCB footprint outweigh the need for the higher bus-fault voltage ratings of the TJA1055 or TJA1044. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin, keep the CANH/CANL traces short and symmetric with characteristic impedance near 120 ohm, and verify that the termination resistance at each end of the bus totals 120 ohm to prevent signal reflections. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical EMC/layout notes drawn from the NXP TJA1057 datasheet family, offering context the manufacturer product page alone does not provide.
TJA1059TK - Dual HS-CAN Transceiver with Standby Mode | NXP
The NXP TJA1059TK is a dual high-speed CAN (HS-CAN) transceiver with integrated standby mode, housed in a 14-pin HVSON (3x4.5 mm) package. It provides the physical interface between a CAN protocol controller (typically a microcontroller) and the physical two-wire CAN bus, supporting differential transmit and receive signaling at data rates up to 1 Mbit/s as defined by ISO 11898-2:2024. A CAN transceiver is the physical-layer analog front-end of a Controller Area Network, the dominant in-vehicle serial bus. It level-translates digital TXD/RXD signals from a microcontroller (typically 3.3V or 5V CMOS logic) to the differential CANH/CANL bus signals that traverse the vehicle harness, while also providing bus protection, dominant bit clamping, and high-impedance bus isolation when unpowered. Key features of the TJA1059TK include two independent HS-CAN transceiver channels in a single package, a low-power standby mode activated through the STB pin, very low quiescent current in standby (suitable for battery-supplied ECUs during key-off), built-in dominant and recessive bit clamping, bus-pin protection against ±8 kV ESD (HBM) and ±6 kV IEC 61000-4-2, and a wide operating voltage range from 4.75 V to 5.25 V. Each channel is also designed to survive 12V load-dump and reverse-battery transients typical of automotive 12V nets. Architecturally, the TJA1059TK integrates two complete ISO 11898-2 transceivers with separate TXD/RXD lines from the host MCU, sharing the supply pins for both channels. The standby mode disables the entire receiver function for power savings while keeping a low-power bus monitor (variants differ). It is fabricated on a robust BiCMOS process optimized for 5V analog operation with high immunity to automotive EMI. Typical applications include automotive body control modules (BCMs), gateway ECUs between CAN segments, powertrain domain controllers, ADAS sensor fusion modules with dual CAN channels, CAN-based industrial sensor networks, and truck/bus chassis control units. The dual-channel integration saves PCB area in space-constrained ECUs and reduces BOM cost versus two discrete single-channel transceivers. When designing with this device, route the CANH/CANL traces as a 120-ohm-impedance differential pair with symmetric length matching. Place a 100nF decoupling capacitor close to VCC, and avoid ground loops by using a single-point low-impedance ground stitch near the transceiver. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on generic search engines - including same-package HVSON options and recommended companion MCUs for dual-channel CAN ECUs.

The NXP Semiconductors TJA1100HN is an IEEE 100BASE-T1 compliant single-port Automotive Ethernet PHY transceiver housed in a 36-pin HVQFN (QFN-36) package with exposed thermal pad. It supports 100 Mbit/s transmit and receive capability over a single unshielded twisted pair (UTP) cable for at least 15 m, optimized for automotive Ethernet backbones and sensor links in advanced driver assistance systems (ADAS). An automotive Ethernet PHY (Physical Layer transceiver) is the analog/digital mixed-signal device that sits between an Ethernet MAC (Media Access Controller) and the physical twisted-pair cable, performing line coding (PAM-3 for 100BASE-T1), clock recovery, echo cancellation, and signal equalization. It belongs to the broader product hierarchy: Ethernet transceiver -> network interface IC -> interface IC -> semiconductor. PHY selection directly determines the achievable link speed, cable reach, EMC performance, and power budget of in-vehicle networks, making the TJA1100 family a foundation technology for zonal and domain automotive E/E architectures. Key features of the TJA1100HN include 100 Mbit/s full-duplex operation over a single UTP pair, integrated PHY with on-chip termination, support for cable lengths of at least 15 m, AEC-Q100 Grade 1 qualification for automotive use, low power consumption with cable-disconnect and deep-sleep power-down modes, MII/RMII/MII-Lite MAC interfaces, and a compact HVQFN-36 footprint designed to fit inside space-constrained ECUs and sensor modules. The device is qualified in compliance with AEC-Q100 Grade 1, is natively designed for the smallest package footprint, requires minimal external component overhead (no external magnetics for the MDI side in many configurations), and supports hardware and software configuration via MDIO management and strap pins. Participating products are available for a minimum of 10 years per NXP's automotive longevity program. Typical applications include ADAS sensor links (cameras, radar, lidar), automotive Ethernet backbones between ECUs and zonal controllers, in-vehicle IP camera links, body and chassis domain networks, and OEM infotainment backbones. Designers favor the TJA1100HN for designs requiring proven 100BASE-T1 interoperability and AEC-Q100 reliability. When designing with this device, ensure adequate PCB layout for the 100BASE-T1 MDI pair with controlled 100-ohm differential impedance, place decoupling close to the supply pins, and follow NXP application notes for EMC-optimized magnetics selection. Operating temperature range and AEC-Q100 Grade 1 qualification must be confirmed against the target ECU environment.

TJA1145AT/FD/0Z - High-Speed CAN FD Transceiver | NXP | 14-SO
TJA1145AT-FD-0Z is an NXP high-speed CAN/CAN FD transceiver designed for automotive applications, supporting data rates up to 5 Mbit/s in the CAN FD fast phase and packaged in a 14-pin SO (SOIC-14) outline. It provides a 1/1 half-duplex CANbus interface between a microcontroller with a CAN protocol controller and the physical bus, while also incorporating FD-passive partial-networking capability that allows the node to ignore CAN FD frames while waiting for a valid wake-up frame in Sleep or Standby mode. A CAN/CAN FD transceiver is a bus interface IC belonging to the broader category of automotive network transceivers, which itself falls under interface ICs and then integrated circuits in the component taxonomy. These devices sit between a low-voltage digital microcontroller and the differential CAN bus, providing the physical-layer translation that lets a 3.5-bit logic signal coexist with multi-node bus topology. Modern CAN FD transceivers extend classic CAN with flexible data-rate support, enabling payload sizes up to 64 bytes and baud rates above 1 Mbit/s. Key features of the TJA1145AT/FD/0Z include a 4.5 V to 5.5 V supply range, low-power Sleep and Standby modes with local and bus wake-up, integrated ±8 kV HBM ESD protection on bus pins (per NXP datasheet), and automotive-grade qualification with an operating junction temperature up to +150 °C. The 'FD' suffix variant adds the FD-passive partial-networking function that distinguishes it from the non-FD TJA1145AT/0Z. Architecturally, the device uses a differential transmitter with slope control for low-EMI operation, a high-impedance differential receiver, and an SPI control interface for mode and configuration management. The half-duplex 1/1 configuration simplifies CAN bus timing by following two cables, and the SOIC-14 footprint allows drop-in compatibility with classic 14-pin CAN transceivers. Typical applications include automotive body and powertrain ECUs, gateway modules, partial-networking nodes in CAN FD bus systems, industrial CAN FD bridges, and diagnostic interfaces supporting UDS and OBD-II. For automotive designs requiring the same part in a 12-pin HVSON package, the TJA1145ATK/FD/0Z offers equivalent functionality in a smaller footprint. When designing with this transceiver, keep the bus termination (typically 120 Ω at each end of the bus) external and place a 100 nF decoupling capacitor close to the VCC pin. Pay attention to the VIO supply if the host MCU runs at 3.3 V, and verify wake-up timing against the network manager's bus-sleep requirements. This page synthesizes distributor pricing from DigiKey, Mouser, and LCSC, plus drop-in alternatives and partial-networking design notes that are not consolidated in a single place on the manufacturer datasheet.
TJA1145T/FDJ - High-Speed CAN FD Transceiver w/ Partial Networking
The NXP TJA1145T/FDJ is a high-speed CAN (Controller Area Network) transceiver with CAN FD (Flexible Data rate) support and dedicated partial networking capability, housed in a 14-pin SO package. The device operates from a 4.5V to 5.5V supply on VCC and is fully compliant with ISO 11898-2:2003, ISO 11898-5:2007, and ISO 11898-6:2013 standards. Per the NXP product page, the TJA1145T variant supports data rates up to 2 Mbit/s. A CAN transceiver is a physical-layer interface that connects a CAN protocol controller to the differential CAN bus, providing differential transmit/receive signaling, bus fault protection, and electromagnetic immunity. The TJA1145T belongs to the NXP TJA1145 family, which integrates ISO 11898-6 selective wake-up logic ('partial networking') so an ECU can ignore CAN traffic while monitoring the bus for a designated wake-up frame, dramatically reducing quiescent current in always-connected body-electronics ECUs. Key features include autonomous bus biasing per ISO 11898-6:2013, an FD-passive mode that ignores CAN FD frames during Sleep/Standby to avoid false wake-ups, low-power Sleep and Standby modes, and an INH (inhibit) output for controlling an external voltage regulator. The 14-SO package provides a small footprint suitable for body-control, gateway, and cluster modules. The TJA1145T/FDJ uses an ISO 11898-6 selective-wake architecture that combines a low-power wake receiver with the high-speed CAN data path. When the host microcontroller commands Sleep mode, the data path shuts down while the wake receiver remains active; only a matching CAN-ID frame wakes the ECU, allowing significant quiescent-current savings versus traditional always-on transceivers. Typical applications include automotive body-control modules (BCM), gateway ECUs, instrument clusters, and ADAS sensor nodes where selective wake-up minimizes parasitic battery drain. The 'T' suffix identifies this specific variant within the TJA1145 family (distinct from TJA1145 and TJA1145A), and the '/FD' suffix denotes CAN FD passive support. When designing with this part, ensure the bus termination (typically 120 ohm at each end of the CAN bus segment) is correctly applied and that the INH pin is used to control an external LDO if low quiescent current is required. Note that TJA1145T is approaching end-of-life; verify current lifecycle status with NXP before committing to new designs.

TJA144x - Dual CAN FD Transceiver Family | NXP Semiconductors
The NXP TJA144x is a family of dual high-speed CAN/CAN FD transceiver ICs that provide an interface between a Controller Area Network (CAN) or CAN FD protocol controller and the physical two-wire CAN bus, supporting data rates up to 5 Mbit/s and compliant with ISO 11898-2, SAE J2284 and AEC-Q100 Grade 0. The family is offered in HVSON-14 (3.6x2.0 mm) and HVSON-8 packages, with variants including Basic, Standby, Dual Standby, and Sleep power modes for different power-management strategies in automotive networks. The TJA144x operates from a 4.5V to 40V supply (load-dump tolerant), tolerates -5V to +45V on the bus pins, and integrates dominant-timeout, thermal shutdown, and bus-pin short-circuit protection. A CAN FD transceiver (also called CAN Flexible Data-rate transceiver) is a physical-layer device that converts digital transmit/receive data from a CAN protocol controller into differential voltage levels on the CANH/CANL bus wires. As the boundary between the protocol controller and the bus medium, it provides dominant/recessive arbitration, common-mode rejection, and EMC robustness required in automotive environments. Within the in-vehicle network hierarchy, the CAN transceiver sits below the microcontroller (MCU) and above the wiring harness, forming the physical layer of the OSI seven-layer reference model for CAN. Key features of the TJA144x family include an ultra-low-current Standby mode with remote CAN wake-up detection, very low electromagnetic emission (EME) and high electromagnetic immunity (EMI), excellent ESD protection (±8 kV HBM on bus pins), and pin compatibility with the prior TJA1042/1051 generations for easy retrofit. The HVSON-14 package exposes an exposed thermal pad for low thermal resistance, and the HVSON-8 variant offers a compact footprint for ECU miniaturization. Devices are AEC-Q100 Grade 0 qualified for automotive temperatures from -40 °C to +150 °C. Typical applications include body control modules (BCM), gateway ECUs, ADAS sensor nodes, instrument cluster CAN backbones, electric-vehicle battery-management communication, and any in-vehicle network that requires migration from classical CAN to CAN FD without redesigning the PCB or firmware. The 5 Mbit/s CAN FD capability is essential for high-bandwidth automotive Ethernet-cascade gateways and radar/LiDAR sensor clusters. When designing with the TJA144x, ensure the VCC supply is decoupled with a 100 nF ceramic capacitor close to pin VCC, and that the bus terminations (typically 120 Ω) are present at each end of the CAN bus segment. The VIO pin on HVSON-14 variants allows level-shifting between the 3.3V or 5V MCU and the 5V transceiver logic domain.
