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.

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.

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.

The NXP TJA1057BTK-0J is a high-speed CAN (Controller Area Network) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus. Housed in an 8-pin HVSON (3x3 mm) package with exposed pad, it supports data rates up to 5 Mbps and is qualified to AEC-Q100 Grade 1 for automotive applications. A CAN transceiver (also called a CAN bus transceiver or CAN interface IC) is a physical-layer device that converts the digital transmit/receive logic signals of a CAN protocol controller inside a microcontroller into the differential CANH/CANL bus signals required on the actual network. CAN belongs to the broader category of serial communication interface ICs, alongside RS-485, RS-232 and LIN transceivers. The TJA1057 family specifically targets high-speed classical CAN and CAN FD (Flexible Data-rate) networks used for powertrain, chassis and body electronics. Key features include a low electromagnetic emission (EME) common-mode choke design, high electromagnetic immunity (EMS), a low-power Standby mode with remote wake-up capability, and ±8 kV HBM ESD protection on the bus pins (per IEC 61000-4-2 on the bus pins, per datasheet). The transceiver operates from a 4.5 V to 5.5 V VCC supply, supports bus voltages from -27 V to +40 V, and provides a TxD dominant time-out for fail-safe behavior. The TJA1057BTK/0J variant carries the 'B' suffix (VIO supply pin present, allowing direct level-shifting to MCUs at 3.3 V or 5 V) and the 'TK' suffix indicating the 8-pin HVSON package with exposed pad. The /0J suffix designates the production ordering code (tape-and-reel packaging). Internally, the device uses a silicon-on-insulator (SOI) process (NXP SOI3+ family), which gives it excellent ESD and latch-up immunity versus older bulk-silicon CAN transceivers like the TJA1050. Typical applications include automotive body control modules (BCMs), gateway ECUs, instrument clusters, HVAC control units, transmission ECUs and industrial CAN nodes operating up to 1 Mbit/s in classical CAN or 5 Mbps in CAN FD networks. The transceiver interfaces directly to NXP S32K and most third-party automotive MCUs. When designing with this part, place the VCC decoupling capacitor (typically 100 nF) directly adjacent to pin 8 and connect the exposed pad (pin 0) to a large PCB ground plane for thermal dissipation and low-impedance return paths. Match the CANH/CANL bus termination to 120 Ω at the network ends to satisfy ISO 11898-2 and avoid signal-integrity issues at high bus loads.
TJA1057GT/1Z - High-Speed CAN Transceiver SOIC-8 | NXP
The NXP TJA1057GT/1Z is a high-speed CAN (Controller Area Network) transceiver from the Mantis family, providing an interface between a CAN protocol controller and the physical two-wire CAN bus, housed in an 8-pin SOIC (SO-8) package. Key specifications include ISO 11898-2:2016 conformance, data rates up to 1 Mbit/s on the TJA1057T variant with CAN FD support on other variants, and automotive-grade temperature operation. What is a CAN transceiver? A CAN transceiver is a physical-layer interface IC that converts digital transmit/receive logic signals from a microcontroller CAN controller into differential voltage signals on a two-wire CAN bus (CANH and CANL). It belongs to the hierarchy: CAN transceiver -> CAN interface IC -> Interface ICs -> Integrated Circuits. The transceiver also provides bus protection, fault tolerance (dominant/recessive clamping, TXD dominant time-out), and EMC/ESD robustness required in automotive environments. Key features of the TJA1057 include very low current consumption in standby and go-to-sleep modes with remote wake-up capability, an integrated VIO supply pin on /3 variants for direct interfacing with 3.3V and 5V microcontrollers, and an undervoltage detection on VCC and VIO supplies. The TJA1057 implements the CAN physical layer per ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, with the TJA1057T explicitly specified for data rates up to 1 Mbit/s. Architecturally, the device uses a differential transmit/receive path with slope control for low-EMI operation, an internal LDO for digital supply, and a sophisticated thermal protection scheme. Its split-pin output stage balances common-mode stability with low electromagnetic emissions, making it well-suited for automotive body, chassis, and powertrain networks. Typical applications include automotive body control modules, gateway ECUs, infotainment CAN nodes, industrial CAN automation nodes, and CAN-FD enabled instrument clusters. Its robustness against ESD (>6 kV HBM) and bus fault voltages (±58 V) makes it dependable in harsh electrical environments. When designing with this device, ensure proper bus termination with 120 ohm resistors at each end of the bus and a common-mode choke for EMI-sensitive applications. The TJA1057 requires careful placement of the VCC decoupling capacitor close to pin 1 to maintain supply stability during dominant-to-recessive transitions. This page synthesizes distributor pricing, drop-in alternative cross-references, and practical design notes not found in the manufacturer datasheet alone.

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. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, including cross-references to TJA1057 family members and other 8-pin high-speed CAN transceivers.
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.

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.

TJA1145T/FDJ - High-Speed CAN FD Transceiver w/ Partial Networking
The NXP TJA1145T/FDJ is a high-speed CAN (Controller Area Network) transceiver with CAN FD (Flexible Data rate) support and dedicated partial networking capability, housed in a 14-pin SO package. The device operates from a 4.5V to 5.5V supply on VCC and is fully compliant with ISO 11898-2:2003, ISO 11898-5:2007, and ISO 11898-6:2013 standards. Per the NXP product page, the TJA1145T variant supports data rates up to 2 Mbit/s. A CAN transceiver is a physical-layer interface that connects a CAN protocol controller to the differential CAN bus, providing differential transmit/receive signaling, bus fault protection, and electromagnetic immunity. The TJA1145T belongs to the NXP TJA1145 family, which integrates ISO 11898-6 selective wake-up logic ('partial networking') so an ECU can ignore CAN traffic while monitoring the bus for a designated wake-up frame, dramatically reducing quiescent current in always-connected body-electronics ECUs. Key features include autonomous bus biasing per ISO 11898-6:2013, an FD-passive mode that ignores CAN FD frames during Sleep/Standby to avoid false wake-ups, low-power Sleep and Standby modes, and an INH (inhibit) output for controlling an external voltage regulator. The 14-SO package provides a small footprint suitable for body-control, gateway, and cluster modules. The TJA1145T/FDJ uses an ISO 11898-6 selective-wake architecture that combines a low-power wake receiver with the high-speed CAN data path. When the host microcontroller commands Sleep mode, the data path shuts down while the wake receiver remains active; only a matching CAN-ID frame wakes the ECU, allowing significant quiescent-current savings versus traditional always-on transceivers. Typical applications include automotive body-control modules (BCM), gateway ECUs, instrument clusters, and ADAS sensor nodes where selective wake-up minimizes parasitic battery drain. The 'T' suffix identifies this specific variant within the TJA1145 family (distinct from TJA1145 and TJA1145A), and the '/FD' suffix denotes CAN FD passive support. When designing with this part, ensure the bus termination (typically 120 ohm at each end of the CAN bus segment) is correctly applied and that the INH pin is used to control an external LDO if low quiescent current is required. Note that TJA1145T is approaching end-of-life; verify current lifecycle status with NXP before committing to new designs. This page synthesizes NXP datasheet excerpts, distributor pricing and stock, drop-in variants from the same TJA1145 family, and practical design notes not consolidated in the manufacturer datasheet alone.

The TJA144x operates from a 4.5V to 40V supply (load-dump tolerant), tolerates -5V to +45V on the bus pins, and integrates dominant-timeout, thermal shutdown, and bus-pin short-circuit protection. A CAN FD transceiver (also called CAN Flexible Data-rate transceiver) is a physical-layer device that converts digital transmit/receive data from a CAN protocol controller into differential voltage levels on the CANH/CANL bus wires. As the boundary between the protocol controller and the bus medium, it provides dominant/recessive arbitration, common-mode rejection, and EMC robustness required in automotive environments. Within the in-vehicle network hierarchy, the CAN transceiver sits below the microcontroller (MCU) and above the wiring harness, forming the physical layer of the OSI seven-layer reference model for CAN. Key features of the TJA144x family include an ultra-low-current Standby mode with remote CAN wake-up detection, very low electromagnetic emission (EME) and high electromagnetic immunity (EMI), excellent ESD protection (±8 kV HBM on bus pins), and pin compatibility with the prior TJA1042/1051 generations for easy retrofit. The HVSON-14 package exposes an exposed thermal pad for low thermal resistance, and the HVSON-8 variant offers a compact footprint for ECU miniaturization. Devices are AEC-Q100 Grade 0 qualified for automotive temperatures from -40 °C to +150 °C. Typical applications include body control modules (BCM), gateway ECUs, ADAS sensor nodes, instrument cluster CAN backbones, electric-vehicle battery-management communication, and any in-vehicle network that requires migration from classical CAN to CAN FD without redesigning the PCB or firmware. The 5 Mbit/s CAN FD capability is essential for high-bandwidth automotive Ethernet-cascade gateways and radar/LiDAR sensor clusters. When designing with the TJA144x, ensure the VCC supply is decoupled with a 100 nF ceramic capacitor close to pin VCC, and that the bus terminations (typically 120 Ω) are present at each end of the CAN bus segment. The VIO pin on HVSON-14 variants allows level-shifting between the 3.3V or 5V MCU and the 5V transceiver logic domain. This page synthesizes distributor pricing, drop-in alternatives within the TJA144x family and from competitor manufacturers, and practical design notes not consolidated on the manufacturer datasheet, giving design engineers a single decision-ready reference for CAN FD physical-layer selection.

The /S1Z suffix indicates the tape-and-reel packaging variant supplied through NXP's automotive-grade distribution channel. A CAN SIC transceiver is a specialized CAN physical-layer device that conditions the bus signal to suppress the resonance and ringing artifacts that occur at higher CAN FD data rates. By smoothing the recessive-to-dominant and dominant-to-recessive edges, the TJA1462 allows networks to operate reliably at 5 Mbit/s and above, extending the usable bandwidth of CAN FD without requiring twisted-pair cable changes or extra bus nodes. The part family belongs to NXP's TJA146x automotive transceiver family, positioned between classical High-Speed CAN transceivers and emerging CAN XL physical-layer devices. Key features include a separate VIO supply pin for logic-level translation to 1.8V, 3.3V, or 5V microcontrollers without level shifters, ultra-low quiescent current consumption in Standby mode for battery-powered ECUs, bus dominant time-out protection, and under-voltage detection on both VCC and VIO rails. The HVSON-8 (3.0 mm × 3.0 mm) package with an exposed thermal pad enables reflow-compatible SMT assembly and provides a low thermal resistance path for dissipating bus-fault energy. AEC-Q100 Grade 1 qualification and an extended -40 °C to +125 °C operating temperature range make the device suitable for under-hood and body-control automotive applications. Typical applications include automotive body control modules, gateway ECUs bridging CAN FD powertrain domains, ADAS sensor nodes, and industrial CAN FD backbones. The Standby mode with wake-up via bus activity allows the part to be used in always-on networks where quiescent current budget is critical. When designing with the TJA1462ATK-S1Z, place the VCC and VIO decoupling capacitors within 2 mm of their respective pins and connect the exposed pad to a continuous ground copper pour for thermal dissipation and EMC performance. The STB (Standby) pin should be driven by a GPIO capable of retaining state across MCU reset to avoid unintended bus state changes during boot.

What is a CAN SIC transceiver? A Controller Area Network (CAN) transceiver is the physical-layer bridge between a CAN protocol controller (typically an MCU's CAN module) and the differential CAN bus. CAN SIC (Signal Improvement Capability) is an enhancement defined in ISO 11898-2:2024 that shapes the transmitted signal edges to reduce ringing on the bus, allowing larger topologies, longer stub lengths, and higher data rates on CAN FD networks. In the broader taxonomy: CAN transceiver -> CAN interface IC -> wireline transceiver -> interface IC -> semiconductor. The TJA1462 belongs to the TJA146x family that brings this signal-improvement behavior into mainstream automotive designs. Key features highlighted in the verified web data include up to 8 Mbit/s data rate, a low-power Standby mode, a VIO supply pin for direct interfacing with 1.8V-5V MCUs, ISO 11898-2:2024 and SAE J2284-1..5 compliance, and an operating temperature range suitable for under-the-hood automotive use. The HVSON8 package has an exposed pad that improves thermal performance and shortens the ground return, both critical for EMI-sensitive automotive bus nodes. Architecturally, the device integrates the physical bus drivers, slope control for SIC, dominant/recessive bit handling, and a low-power Standby state that can be commanded by the host. By meeting the latest ISO 11898-2:2024 third edition, it is forward-compatible with emerging CAN XL networks and protects existing designs from obsolescence. Typical applications include automotive body and chassis ECUs, CAN FD gateways, powertrain nodes transitioning from classical CAN, industrial CAN FD backbones needing SIC behavior, and any design replacing older CAN transceivers with a Standby-capable SIC part. When designing with this device, pay attention to bus termination (120 ohm at each end), common-mode choke selection, and decoupling of both VCC and VIO to minimize bus emissions. The VIO pin allows the TXD/RXD logic side to be powered at the same rail as the host MCU, eliminating level shifters.

The NXP TJA1462BT is a CAN FD signal improvement capability (SIC) transceiver with Standby mode in an 8-pin SO (SOIC-8) package, supporting data rates up to 8 Mbit/s on the CAN bus. It is part of the TJA146x family that implements CAN Signal Improvement Capability (SIC) per ISO 11898-2:2024 third edition and CiA 601-4, with full interoperability to classical CAN and CAN FD controllers. A CAN transceiver (sometimes called a CAN bus transceiver or CAN physical-layer interface) is the analog interface between a digital CAN protocol controller and the differential CAN bus wires. It converts digital transmit (TXD) bits from the controller into differentially driven bus levels on CANH and CANL, and converts received bus levels back into digital RXD bits, providing galvanic isolation level shifting and ESD protection for the controller. Key features include bus signal improvement that reduces ringing on the CAN bus, allowing larger topologies and higher data rates than classical HS-CAN transceivers. The device operates from a 4.5 V to 5.5 V VCC supply, supports up to 8 Mbit/s in CAN FD networks, and offers a low-power Standby mode entered via the STB pin. The TJA1462 is intended as a pin-compatible drop-in replacement for the TJA1042 or TJA1044 from NXP, enabling direct retrofit without hardware or software changes. The architecture uses a fully differential driver with slope control and integrated bus failure protection, including TXD dominant time-out, bus dominant time-out, and overtemperature shutdown. Receiver symmetry is trimmed to provide reliable operation at recessive voltages as low as 0.5 V on the bus. Typical applications include automotive ECUs, body control modules, gateway ECUs, industrial CAN nodes, and any node that needs to coexist with mixed CAN FD / classical CAN networks on the same bus segment, where the SIC function reduces the required bit time and improves EMC behavior on long stubs. When designing with the TJA1462BT, place a 100 nF decoupling capacitor close to pin 8 (VCC) and ensure the bus termination (typically 120 ohm at each end of the bus) is present. Use the STB pin to enter Standby when the node is inactive to reduce quiescent current, and verify that the bit timing of the CAN controller remains within ISO 11898-2:2024 limits for SIC operation.

The NXP Semiconductors TJA1463ATK/0Z is a CAN Signal Improvement Capability (SIC) transceiver with Sleep mode, supporting CAN FD communication up to 8 Mbit/s and housed in a 14-pin HVSON (SOT1086-1) package. It implements the SIC behavior defined in CiA 601-4 and ISO 11898-2:2024 parameter set C, while remaining fully interoperable with classical CAN and CAN FD nodes defined by ISO 11898-2:2024 and SAE J2284-1 through J2284-5. The /0Z suffix denotes the tape-and-reel, 100% matte-tin lead-free, Pb-free, AEC-Q100-qualified automotive-grade ordering code. A CAN SIC (CAN Signal Improvement Capability) transceiver is a physical-layer device that sits between a CAN protocol controller and the differential CAN bus, translating the controller's TX/RX logic into the bus's dominant/recessive differential signaling. The "signal improvement" function actively damps the dominant-to-recessive edge ringing that traditionally limits CAN FD bus length and stub density, allowing larger topologies than classical HS-CAN. In the system hierarchy it belongs to: CAN transceiver -> network interface IC -> interface IC -> integrated circuit -> semiconductor. Key features include up to 8 Mbit/s CAN FD data rate, tight bit-timing symmetry enabling communication at 5 Mbit/s with a higher node count, an integrated low-power Sleep mode with remote wake-up via bus activity, a separate VIO supply pin for flexible MCU interfacing from 1.8V to 5V, an STB (standby) mode pin, and an ERR output pin that flags local and global bus failures. The HVSON-14 package provides a small PCB footprint with a thermal pad for improved dissipation in ECU environments. Architecturally the TJA1463ATK/0Z combines a high-speed differential bus driver/receiver pair, an internal slope-control/SIC current-shaping network, a low-drop VIO level shifter, a low-quiescent Sleep regulator with bus-wake comparator, and ESD protection rated to IEC 61000-4-2 on the bus pins. The SIC behavior is achieved without external components - just the standard CAN bus termination and a 5V or 3.3V VCC. Typical applications include automotive body controllers, ADAS sensor nodes (radar, lidar, camera ECUs), chassis and powertrain ECUs, battery management systems (BMS) and battery energy storage system (BESS) communication links, industrial CAN FD backbones, and any classical-CAN network that is being migrated to CAN FD with longer cables or more nodes than the legacy bus can support. When designing with this part, ensure VIO matches the host MCU supply, place the bus termination (typically 120 ohm at each bus end) within the recommended layout, and follow NXP's EMC and ESD layout guidance in the application notes. The Sleep pin and the VIO domain must be sequenced correctly to enter and exit Sleep cleanly.

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

TJF1051T/3/1J - High-Speed CAN Transceiver, SO-8 | NXP
The NXP TJF1051T/3/1J is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and the differential two-wire CAN bus, packaged in an 8-pin SO (SOIC-8) surface-mount package. It supports data rates up to 5 Mbit/s and implements the CAN physical layer defined by ISO 11898-2:2003, ISO 11898-5:2007, and the pending ISO 11898-2:2016 update. A CAN transceiver is the analog front-end that converts the digital TXD/RXD logic levels of a microcontroller into the differential dominant/recessive signalling required on the CAN bus, while also providing ESD protection, bus fault tolerance, and common-mode rejection. The TJF1051T/3 family adds a VIO level-adapter supply pin that allows direct interfacing to microcontrollers with supply voltages from 3V to 5V, simplifying mixed-voltage designs where the MCU runs at 3.3V but the bus nodes may operate at 5V. Key features include an extremely low ElectroMagnetic Emission (EME) due to built-in slope control on the CANH/CANL outputs, a Silent mode (S) input for low-power bus monitoring without disturbing traffic, and high immunity to ElectroMagnetic Interference (EMI) on the bus lines. The device also includes thermal shutdown, bus dominant time-out protection, and an undervoltage detector on VCC and VIO, ensuring robust behaviour on harsh automotive or industrial bus networks. It is the pin-compatible successor to the TJA1051 with improved EMC behaviour and tighter parametric compliance with the ISO 11898-2:2016 specification. Typical applications include automotive body and chassis CAN nodes, industrial CANopen networks, building automation, and any MCU-to-CAN-bus interface requiring 3.3V or 5V logic compatibility with low EME and high EMI immunity. Compared with older TJA1050/TJA1040 designs, the TJF1051T/3 provides substantially reduced electromagnetic emissions, removing the need for external common-mode chokes in many layouts. When designing with this part, place the VIO decoupling capacitor as close as possible to pin 5 and ensure both VCC and VIO are present before TXD transitions are applied. The Silent mode pin must be tied LOW for normal operation or driven by the MCU when bus diagnostics or low-power standby states are required. The /1 JTR suffix indicates 2500-piece reel packaging.
TJF1052IT - Galvanically Isolated High-Speed CAN Transceiver | NXP
The NXP Semiconductors TJF1052IT is a galvanically isolated high-speed CAN transceiver that provides an isolated interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus, delivered in a 16-pin SOIC package with 1 kV / 2.5 kVrms integrated isolation and 2 Mbps data rate support. According to NXP's product page, this part is specifically targeted at industrial applications where galvanic isolation barriers are required, eliminating the need for a separate digital isolator plus isolated DC-DC bias supply. A CAN transceiver is a physical-layer device that converts digital transmit/receive logic from a CAN controller into the differential voltage signaling required by the ISO 11898-2 CAN bus standard, and vice versa. The TJF1052IT integrates the transceiver with on-chip galvanic isolation, placing it in the hierarchy: physical-layer transceiver -> automotive/industrial bus interface -> CAN interface IC -> Interface IC. Integrated isolation removes the need for external optocouplers, isolation transformers, or digital isolator ICs, simplifying PCB layout and reducing BOM count in industrial CAN nodes. Key features include 2 Mbps CAN FD data rate support, 1 kVrms (variant /1Y) or 2500 Vrms (variant /2Y) isolation withstand voltage, 20 kV/us common-mode transient immunity (CMTI), and integrated isolated DC-DC bias supply so the bus-side node can be fully floating. Variants such as TJF1052IT/1Y, TJF1052IT/2Y, and TJF1052IT/5Y differ primarily in isolation voltage rating, with the /5Y variant qualified for functional safety contexts. The 16-SOIC wide-body (7.50 mm) package provides the clearance and creepage distances needed to meet reinforced insulation requirements. Typical applications include isolated industrial CAN nodes (PROFIBUS-style networks), PLCs, battery management systems, solar inverters, and any industrial control bus where the node must float at high common-mode voltage relative to the host. The device operates from a single 3.3 V or 5 V supply on the logic side and includes thermal shutdown, bus dominant time-out, and TXD/RXD logic pins compatible with standard CAN controllers. When designing with this part, ensure that the wide-body SOIC creepage/clearance around the package meets the end-equipment's pollution degree and over-voltage category. Designers do not need an external isolated bias supply, but should still include proper PCB edge plating and slot routing to preserve the integrated isolation rating. Use NXP's application note on isolated CAN node design for layout guidance.
TJF1052IT/1Y - Isolated High-Speed CAN Transceiver | NXP | 16-SOIC
The NXP TJF1052IT/1Y is a galvanically isolated high-speed CAN (Controller Area Network) transceiver housed in a 16-pin SOIC wide-body (7.50 mm width) package. Per the NXP datasheet, it provides 1000 Vrms of galvanic isolation between a CAN protocol controller and the physical two-wire CAN bus, delivering 2 Mbps data rate capability with 20 kV/µs common-mode transient immunity (CMTI). The device integrates NXP's proprietary isolation technology with the proven TJA1052 CAN physical layer, eliminating the need for a separate digital isolator and isolated DC-DC power supply on the bus side. A CAN transceiver (also called a CAN PHY) is the physical-layer interface between a CAN protocol controller and the differential CAN bus. In industrial systems, galvanic isolation between the low-voltage controller domain and the high-voltage bus domain protects sensitive microcontrollers from ground loops, surge events, and high common-mode voltages. The TJF1052i family extends the standard CAN transceiver by embedding this isolation barrier inside the IC, simplifying PCB layout and reducing BOM count compared to discrete isolator-plus-transceiver designs. Key features include integrated 1 kVrms isolation, 2 Mbps CAN FD (Flexible Data-rate) capability, low loop delay suitable for CAN FD frames, thermal protection, bus-dominant time-out, and a silent mode for selective wake-up. The device supports the ISO 11898-2 physical-layer standard and is specifically targeted at industrial automation, energy distribution, and medical equipment applications where reinforced isolation is mandatory. Internally, the TJF1052i combines a capacitive- or transformer-based isolation barrier with a CAN transceiver core on a single silicon die. The wide-body SOIC package provides the required creepage and clearance distances for 1 kVrms isolation, while the exposed pad aids thermal dissipation during sustained bus transmission. The result is a CAN transceiver that satisfies both functional isolation and basic insulation requirements in a single chip. Typical applications include industrial PLC communication modules, grid-tied smart-meter networking, photovoltaic inverter CAN buses, battery management system (BMS) communication links, electric-vehicle charging-station controllers, and isolated sensor networks in process automation. Designers reach for the TJF1052i when they need CAN connectivity in a high-voltage environment without the complexity of a multi-chip isolated solution. When designing with this part, mind the wide-body 7.50 mm SOIC footprint - it is wider than a standard 150-mil SOIC, so PCB land pattern and creepage must accommodate it. Also confirm that the upstream 5 V or 3.3 V controller rail is well decoupled; the isolated bus side derives its own internal supply through the on-chip isolation transformer/charge pump, so no external isolated supply is required.
