THVD1552D - 5V RS-485 Transceiver, ±18kV IEC ESD, 50Mbps | TI
The Texas Instruments THVD1552D is a 5V RS-485/RS-422 transceiver with ±18kV IEC ESD protection on the bus pins, supporting data rates up to 50 Mbps in a 14-pin SOIC (D) package. It integrates one driver and one receiver (1/1) in a full-duplex configuration, operating from a single 4.5V to 5.5V supply with a typical quiescent current of approximately 4 mA. A RS-485 transceiver is a physical-layer interface IC that converts the differential logic levels of a UART or controller into the balanced, half-duplex signaling required by the TIA/EIA-485-A standard. As a member of the RS-485/RS-422 interface IC family within the broader interface IC category and signal conditioning/isolation hierarchy, it enables robust multi-drop communication over twisted-pair cable in electrically noisy industrial environments. The THVD15xx family specifically targets rugged industrial applications where IEC-level surge, fast transient, and ESD events would otherwise require external protection components. Key features include ±18kV IEC 61000-4-2 ESD protection on bus pins, ±2kV IEC 61000-4-4 EFT immunity, a wide common-mode range of -7V to +12V allowing up to 256 nodes on the bus, and thermal shutdown with short-circuit protection on the driver outputs. The receiver failsafe design guarantees a known logic-high output when the bus is open, shorted, or idle, eliminating the need for external biasing resistors. Internally, the THVD1552D uses a differential line driver with slew-rate control suitable for 50 Mbps signaling, paired with a differential comparator receiver with 50 mV typical input hysteresis. The half-duplex architecture shares bus pins between driver and receiver, and the full-duplex variant (THVD1552) provides separate driver output and receiver input pins. Typical applications include industrial fieldbus networks (Modbus, PROFIBUS), motor drive encoder links, building automation (BACnet, KNX), solar inverter daisy-chain communications, and any point-to-point or multi-drop RS-485 link requiring IEC-level robustness. Designers typically pair it with a TVS diode array on the bus for additional surge immunity. When designing with this device, place 100 nF decoupling capacitors as close as possible to the VCC pin and add a 1 µF bulk capacitor on the bus-side supply rail. The exposed pad must be soldered to a continuous ground plane for thermal dissipation. Maintain 100 Ω termination at both cable ends to suppress reflections at 50 Mbps.

THVD1552DGS - 5V RS-485 Transceiver, ±18kV IEC ESD | TI
The Texas Instruments THVD1552DGS is a 5-V RS-485 transceiver with integrated ±18-kV IEC 61000-4-2 ESD protection, delivered in a 10-pin VSSOP (DGS) package with extended −40 °C to +125 °C industrial temperature support. It provides one driver and one receiver (1/1) for full-duplex RS-422/RS-485 communication at signaling rates up to 50 Mbps, suiting both multi-drop industrial backbones and high-speed point-to-point links. Background: an RS-485 transceiver is a physical-layer interface IC that translates a low-voltage differential logic signal on a UART or SPI controller side to the rugged, balanced differential bus levels defined by the TIA/EIA-485A standard. By sitting between the application MCU and the twisted-pair cable, it provides the bus biasing, line driving strength, and ESD/EFT immunity required for industrial environments where long cable runs pick up motor noise, lightning surges, and hot-plug transients. Key features include a 4.5 V to 5.5 V single-supply operating range, ±30-kV HBM bus-pin ESD (human-body model), ±18-kV IEC 61000-4-2 contact discharge, ±25-kV IEC 61000-4-2 air-gap discharge, and integrated IEC 61000-4-4 EFT immunity that removes the need for external TVS protection on the bus. The receiver failsafe design guarantees a known logic output when the bus is idle, shorted, or open. Architecturally, the THVD1552 uses a differential line driver with slew-rate-limited outputs and a wide-common-mode receiver that meets the TIA/EIA-485A standard, allowing up to 256 transceivers on a single bus when using lower-speed family members (the THVD1552 is optimized for higher speed). The half-/full-duplex variants in the THVD15xx family share the bus-pin ESD cell, simplifying multi-protocol design. Typical applications include factory automation PLC backplanes, motor-drive communication links, solar inverter telemetry, building-automation RS-485 trunks, and any cable runs through noisy industrial cabinets. When designing with this part, place 100 nF decoupling close to VCC and use a 120 Ω termination at the bus ends only. Total bus load (stub length and cable capacitance) limits the maximum signaling rate, so verify cable length against the 50-Mbps data-rate budget.

THVD1552DR - 5V RS-485 Transceiver, ±18kV ESD | 14-SOIC | TI
The Texas Instruments THVD1552DR is a 5-V full-duplex RS-485/RS-422 transceiver housed in a 14-pin SOIC (D) package, integrating ±18-kV IEC 61000-4-2 ESD protection on the bus pins. It supports a signaling rate up to 50 Mbps and operates across a wide 3 V to 5.5 V supply range, making it a robust interface for industrial and noisy environments where reliable differential communication is required. An RS-485 transceiver is a physical-layer (PHY) device that converts a single-ended UART/logic signal into a differential signal suitable for transmission over twisted-pair cabling while meeting the TIA/EIA-485 standard. This PHY sits within the broader OSI stack between the controller UART (data-link layer) and the physical medium (cable), under the family name of serial-interface ICs. The THVD1552 belongs to the THVD15xx sub-family of noise-immune TI transceivers, sharing pinouts and feature sets across half- and full-duplex variants. Key features include ±18-kV IEC 61000-4-2 contact/air-discharge ESD protection directly on bus pins (driver output and receiver input), ±4-kV IEC 61000-4-4 EFT immunity, an internal fail-safe biasing on the receiver output for open/short bus conditions, 1/8 unit-load support (up to 256 nodes on a single bus), and a wide -40 °C to +125 °C operating temperature range. The 14-SOIC footprint is industry standard for this class and supports reflow-solder assembly. The THVD1552 uses a CMOS process with integrated TVS-style ESD structures on the bus pins; this allows designers to replace external protection components, BOM cost, and PCB area. Internal fail-safe circuitry guarantees a logic-high receiver output when the bus is idle, shorted, or terminated but undriven — critical for deterministic polling protocols such as Modbus. Typical applications include motor-control feedback links, multi-drop industrial sensor buses, building automation nodes (BACnet/MS-TP, Modbus RTU), solar inverter inter-module communication, and any 3.3-V or 5-V MCU UART-to-RS-485 bridge requiring strong system-level ESD/EFT robustness. When laying out this part, place the bus-side 120 Ω termination as close to the IC bus pins as possible, route the differential pair A/B symmetrically, and keep the bus stub length under one-tenth of the signal rise time (about 30 mm at 50 Mbps) to preserve signal integrity. This page consolidates distributor stock/pricing, drop-in alternative listings, and PCB design notes not found in the TI datasheet alone, accelerating engineer selection for noise-immune RS-485 designs.
TIC10024QDCPRQ1 - 24-Input Automotive MSDI w/ SPI | Texas Instruments
The Texas Instruments TIC10024QDCPRQ1 is an automotive-grade 35-V Multiple Switch Detection Interface (MSDI) with SPI, housed in a 38-pin HTSSOP package with exposed thermal pad (DCP). It monitors 24 direct switch inputs (10 configurable for ground- or supply-referenced switches), integrates adjustable wetting current sources per channel, and reports switch state through an SPI-compatible serial port — eliminating up to 24 discrete comparator/MCU GPIOs in a BCM (Body Control Module). A Multiple Switch Detection Interface (MSDI) is a mixed-signal ASSP that bridges mechanical switches (e.g. rocker switches, momentary buttons, limit switches) to a microcontroller in 12-V automotive electrical systems. It belongs to the broader hierarchy: switch interface IC → interface IC → signal conditioning IC → power management / body electronics ASSP → automotive semiconductor. The MSDI provides per-input wetting current to prevent contact oxidation, programmable threshold comparators for switch-closed detection, and serial aggregation of 24 inputs into a few SPI pins — reducing wire harness complexity and MCU pin count. Key features include 35-V absolute maximum load-dump tolerance (12-V nominal), adjustable wetting current per channel, selectable ground- or supply-referenced inputs on 10 channels, integrated input debounce / de-glitch filters, configurable interrupt generation for wake events, low quiescent current sleep mode, and SPI communication up to [DATA_NEEDED: SPI clock rate]. The device operates across -40 °C to +125 °C ambient (AEC-Q100 Grade 1) and includes thermal shutdown protection. The exposed-pad HTSSOP-38 package provides theta_JA suitable for BCM thermal environments. Technically, the TIC10024-Q1 uses a per-channel comparator architecture with current-mode wetting sources driven from a shared internal regulator. The SPI peripheral implements a standard mode-0 protocol with a frame-format error flag and a global wake-up interrupt output. Internal state machine handles input filtering, hysteresis, and wetting-current modulation; channel configuration registers enable per-input current programming and pull-up/pull-down selection. Typical applications include automotive body control modules (BCM) reading 24 switches per chip, gateway/zonal controllers monitoring door/trunk/hood latches, steering-wheel switch matrices, seat-control switch aggregation, and overhead-console button clusters. The 24-input density lets a single MSDI replace multiple 8-/16-channel general-purpose I/O expanders. When designing with this part, ensure the PCB layout accommodates the exposed thermal pad with at least 4 thermal vias to the inner ground plane for AEC-Q100 thermal conformance. The 38-pin HTSSOP package requires careful routing of SPI traces; keep the SCLK/MOSI/MISO bundle length-matched and routed away from VBAT-switching nodes.

TIR1000IPWR - Standalone IrDA Encoder/Decoder | TI | 8-TSSOP
The Texas Instruments TIR1000IPWR is a standalone IrDA (Infrared Data Association) SIR (Serial Infrared) encoder/decoder IC housed in an 8-pin TSSOP (PW) package and rated for the -40C to +85C industrial temperature range. It encodes and decodes asynchronous UART bit streams into IrDA-compliant 3/16 pulse-modulated optical signals at data rates from 1200 bps up to 115.2 kbps, and operates from a 2.7 V to 5.5 V supply. The TIR1000IPWR is the tape-and-reel (R) packaging variant of the TIR1000IPW die, which is functionally identical to the legacy TIR1000IPWRG4. An IrDA encoder/decoder is a specialized interface IC that sits between a host microcontroller's UART and an external infrared transceiver (typically a PIN photodiode + LED pair). It performs the bit-stuffing and pulse-width modulation required by the IrDA physical layer so the host CPU only sees a transparent serial stream; the broader category belongs to interface ICs in the connectivity hierarchy (interface IC > transceiver > encoder/decoder). Key features include 1200-bps to 115.2-kbps IrDA 1.0 / HPSIR compliance, single 2.7 V to 5.5 V supply, direct UART handshake interface, low-power shutdown mode, and CMOS construction. The TIR1000IPWR adds an infrared port to any standard UART, eliminating the need for bit-banging IR protocols in firmware and offloading real-time pulse-width timing from the host MCU. The architecture uses a baud-rate generator derived from an external 16x clock (typically the UART's reference), a transmit pulse shaper that converts the UART TX bit stream into 3/16-width IR pulses, and a receive decoder that recovers the UART RX stream from the demodulated IR input. Because it is a pure logic encoder (no onboard LED driver), the host must add a discrete IR transceiver module (e.g., a TFDU4100 / HSDL-3201 class device) to drive the optical front end. Typical applications include IrDA ports on PDAs, industrial handhelds, medical data terminals, point-of-sale (POS) equipment, and consumer electronics printers. The wide supply range and 8-pin TSSOP package make it suitable for space-constrained designs that need to retrofit IrDA onto an existing UART. A key design consideration is clock sourcing. The TIR1000IPWR requires a 16x baud-rate reference clock (XCLK), which is normally derived from the host UART's baud-rate generator; if the host baud rate changes, XCLK must be reprogrammed accordingly. The IC does not include the optical transceiver, so a separate IrDA transceiver module must be added externally. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single reference for IrDA encoder/decoder selection.
TJA1021T/20/C - LIN 2.1 Transceiver, 20kBd, 8-SO | NXP
The NXP TJA1021T/20/C is a single-wire LIN (Local Interconnect Network) bus transceiver that operates as the physical interface between a LIN protocol controller and the physical bus in in-vehicle sub-networks. The /20 variant supports baud rates from 1 kBd up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, SAE J2602 and ISO 17987-4:2016. It is housed in an 8-pin SO (SOIC-8) surface-mount package and is pin-to-pin compatible with the legacy TJA1020 and NXP MC33662(B) LIN transceivers. What is a LIN transceiver? A LIN transceiver is a physical-layer (PHY) device that translates the low-voltage digital logic signals (TXD/RXD) generated by a microcontroller or LIN controller into the single-wire, dominant/recessive, slew-rate-controlled bus waveform defined by the LIN standard. It handles bus fault protection (short to battery, short to ground, load-dump), ESD protection, thermal shutdown, and wake-up detection via the bus line. The LIN protocol is widely used as a low-cost sub-bus for non-critical automotive body electronics (mirror controls, seat adjusters, door modules, roof consoles), where CAN would be over-spec. Key features of the TJA1021T/20/C include an integrated slew-rate-controlled LIN bus driver that meets the LIN 2.1/SAE J2602 wave-shaping requirements with minimized electromagnetic emissions (EME), improved ESD robustness compared to the TJA1020, a -27 V to +40 V wide bus load-dump protection range, low-power sleep mode with remote wake-up via the LIN pin, and a dedicated TXD dominant time-out to prevent the bus from being permanently driven. Architecturally, the TJA1021T/20/C uses a bipolar high-voltage process for the bus-side driver stage combined with low-voltage CMOS logic on the protocol-side (TXD, RXD, EN, WAKE). The integrated pull-up resistor on the bus line and the internal slope-control feedback loop produce the trapezoidal LIN waveform specified by SAE J2602, eliminating the need for an external diode or waveform-shaping RC network. Built-in fail-safe features include loss-of-bat handling, ground-shift tolerance, and under-voltage reset on VCC. Typical applications include automotive body-control modules, LIN slaves for door/window/seat/steering-column control, HVAC flap motors, mirror adjusters, ambient lighting nodes, and rain/light sensors. Because the part is qualified to the AEC-Q100 automotive reliability standard, it is designed for the harsh electrical environment of a 12 V automotive battery rail, including jump-start and load-dump transients. It also suits industrial LIN sub-buses where the LIN standard provides a simple, robust single-wire alternative to CAN or RS-485. When designing with this device, ensure the master resistor (typically 660 ohms pull-up to VSUP through a diode) and the bus capacitor (typically 220 pF to 1 nF) are correctly sized, and that the LIN node wake-up strategy (local wake via the WAKE pin vs remote wake via the bus) matches the application requirements.
TJA1022HGZ - Dual LIN 2.2A/SAE J2602 Transceiver DHVQFN-24 | NXP
The NXP Semiconductors TJA1022HGZ is a dual-channel LIN (Local Interconnect Network) 2.2A/SAE J2602 transceiver in a 24-pin DHVQFN (5.5 x 3.5 mm) exposed-pad package. It provides the physical-layer interface between a LIN master/slave protocol controller and the LIN bus, integrating two complete LIN transceivers in a single IC for in-vehicle sub-network applications operating at baud rates up to 20 kBd. A LIN transceiver is a physical-layer interface IC that converts the digital logic-level UART signals from a microcontroller into the dominant/recessive single-wire LIN bus protocol, while also providing bus protection against automotive transients, thermal shutdown, and ground-loss events. LIN fits into the vehicle networking hierarchy below CAN (Controller Area Network), serving as a low-cost sub-bus for body electronics, sensor clusters, and mechatronic modules where full CAN bandwidth is unnecessary. Key features include LIN 2.0/2.1/2.2/2.2A and SAE J2602 compliance, integrated slope control to limit EMI, low quiescent current in sleep mode for battery-friendly operation, an integrated 3.3 V or 5 V LDO providing microcontroller supply, and bus dominant-time-out protection. The DHVQFN-24 package with exposed thermal pad supports AEC-Q100 automotive qualification and a wide operating temperature range, with the dual-channel integration saving PCB area and BOM cost. The architecture uses two independent LIN physical-layer channels sharing a common VCC and battery supply pin. Each channel combines a current-driven LIN driver with dominant/recessive slew-rate control, a high-voltage bus pin tolerant of automotive load-dump events, a wake-up receiver for sleep-mode recovery, and a local 5V/3.3V LDO that can power a host microcontroller. Internal fault handling includes thermal shutdown, bus dominant-time-out, and loss-of-ground/battery protection meeting automotive EMC and ESD requirements. Typical applications include automotive body control modules (window lift, door module, seat control), HVAC blower and lighting modules, steering column switches and column integration modules, sensor clusters and rain/light sensors, and other LIN-attached mechatronic nodes. Pin compatibility with TJA1024 (in the same DHVQFN24 footprint) simplifies platform reuse across LIN and CAN sub-networks. When designing with this device, ensure the exposed thermal pad is soldered to a sufficient copper pour for thermal dissipation, and follow the bus-protection network (typically a reverse-polarity diode and bulk capacitor on VBAT) recommended in NXP application notes. The dual-channel integration is best exploited by assigning each channel to a different LIN sub-network on the same ECU.
TJA1022TK - Dual LIN 2.2A Transceiver HVSON14 | NXP
The NXP Semiconductors TJA1022TK is a dual LIN (Local Interconnect Network) transceiver in a 14-pin HVSON (3x4.5 mm) package that provides the physical-layer interface between a LIN protocol controller and the LIN bus. It supports baud rates up to 20 kBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602, making it suitable for in-vehicle subnetwork applications. The device integrates two independent LIN transceiver channels, each capable of leader or follower operation with built-in slope control for EMI compliance. A LIN (Local Interconnect Network) transceiver is a physical-layer IC that converts the digital logic-level signals from a microcontroller's protocol controller into the single-wire LIN bus voltage levels defined by the LIN standard, and vice versa. LIN sits below CAN in the automotive networking hierarchy (sub-bus: LIN -> sub-bus of CAN -> in-vehicle network), enabling low-cost communication for body electronics such as door modules, seat controllers, mirror adjusters, and roof consoles. The TJA1022's dual-channel integration halves the cell density on the PCB versus two discrete transceivers. Key features include an operating supply voltage range typically suitable for 12 V automotive systems, integrated LIN bus termination, thermal shutdown protection, bus pin transient protection per ISO 7637, and very low quiescent current in sleep mode for battery-friendly standby. The device supports both normal and silent-mode operation for selective wake-up scenarios. Per the NXP datasheet, the TJA1022T and TJA1022TK are pin-compatible with the legacy TJA1020, TJA1021, TJA1027, and TJA1029 single LIN transceivers in SO14 / HVSON14 packages. The TJA1022TK architecture combines two independent LIN physical-layer blocks sharing common supply and ground pins. Each channel includes a wave-shaping driver with controlled slew rate to meet LIN EMC requirements, a dominant-timer for bus lock-up protection, and a wake-up receiver. The HVSON14 exposed pad provides a low thermal resistance path, essential for engine-bay and under-hood modules where ambient temperatures can reach 125 C. Typical applications include automotive body-electronics modules (door, seat, mirror, roof), HVAC control panels, steering-wheel button interfaces, LED lighting controllers, and powertrain sensors connected to a body-domain LIN sub-bus. The dual-channel integration is especially valuable in door-modules and seat-modules where multiple LIN sub-nets reduce harness weight and BOM cost. When designing with this part, follow NXP's reference layout guidance: place the HVSON14 exposed pad on a continuous ground copper pour with multiple thermal vias, keep the LIN bus traces short, and add the recommended external reverse-battery and ESD protection on the LIN pins if the module is exposed to handling transients.

TJA1024HG - Quad LIN 2.2A/SAE J2602 Transceiver | NXP
The NXP Semiconductors TJA1024HG is a quad LIN (Local Interconnect Network) 2.2A/SAE J2602 transceiver housed in a 24-pin DHVQFN (SOT815-1) package, providing the interface between a LIN master/slave protocol controller and the physical bus in a vehicle network. It comprises two independent and separated dual LIN transceiver channels, supports baud rates up to 20 kBd, and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602 standards. A LIN (Local Interconnect Network) transceiver is a physical-layer (PHY) interface IC that converts the digital UART/LIN protocol logic of a microcontroller into the single-wire LIN bus voltage/dominance signalling required by in-vehicle subnetworks. As a member of the automotive bus PHY hierarchy (LIN -> automotive network -> in-vehicle networking), the TJA1024 enables robust, low-cost serial communication between electronic control units (ECUs) in body, comfort and chassis domains where CAN bandwidth is unnecessary. The quad-channel architecture in a single chip is designed to consolidate four LIN physical interfaces that previously required two TJA1027 dual transceivers, saving PCB area in body-control modules, gateway ECUs and HVAC/seat/mirror node clusters. Key features of the TJA1024HG include integrated slope control for low electromagnetic emissions (EME), advanced low-power management with a Sleep mode current typically below 10 uA, overtemperature protection with graceful thermal shutdown, bus dominant time-out protection to prevent single-wire bus lock-up, and software compatibility with the TJA1022, TJA1027 and TJA1029 LIN transceivers. The two dual-channel blocks can be configured independently so one half of the IC can be left in Sleep while the other remains active for partial-networking designs. The TJA1024HG uses a bipolar/BiCMOS output stage that delivers up to 2.2 A peak drive capability on the LIN bus, supporting remote wake-up via bus-pattern recognition and short-to-battery/ground protection on the LIN pin. Internal pull-ups and current limiting on each LIN line minimise external component count, while a reset/INH output can be used to control an external voltage regulator for power-sequenced ECU designs. Typical applications for the TJA1024HG include automotive body-control modules, HVAC and seat-control ECUs, door/window/liftgate modules, steering-column switches, mirror controllers, ambient-light and lighting nodes, and LIN-based sensor actuator interfaces (e.g. smart MOSFET pre-drivers, rain/light sensors). Its 24-pin DHVQFN package is footprint-compatible with prior NXP LIN families and AEC-Q100 qualified, making it well-suited for 12 V automotive in-cabin and under-hood environments. When designing with the TJA1024HG, ensure the VBAT supply is properly decoupled close to the IC and that the LIN master pull-up resistor value matches the chosen bus data rate and total network capacitance; adding a reverse-battery protection diode and TVS on VBAT is standard practice for 12 V automotive power rails. Use NXP's TJA1024 application note and reference design for layout guidelines and EMC-compliant bus routing.

TJA1024HGZ - Quad 20 kBd LIN 2.2A Transceiver | NXP
NXP Semiconductors TJA1024HGZ is a quad LIN 2.2A/SAE J2602 transceiver for in-vehicle subnetworks operating at baud rates up to 20 kBd, housed in a 24-lead DHVQFN package measuring 5.5 mm by 3.5 mm. The device supports LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602 requirements identified in the supplied source data. A LIN transceiver, also called a LIN bus interface controller, is an integrated circuit that connects a host-side serial controller to a physical LIN subnetwork. It belongs to the hierarchy of bus interface IC, communication transceiver, vehicle network interface, and semiconductor. The TJA1024HGZ integrates four LIN channels, allowing one controller to connect to multiple low-speed vehicle-network nodes while retaining individual fault-management capabilities. The TJA1024 family converts controller-generated data streams into LIN bus signals shaped to reduce electromagnetic emissions, as stated in the NXP datasheet excerpt. Its LIN bus outputs are pulled high through internal termination resistors. The part is software compatible with the TJA1022, TJA1027, and TJA1029, making it useful when an established LIN protocol stack must connect to this physical-layer transceiver. This transceiver is intended for automotive and other LIN-capable subnetwork systems using communication rates up to 20 kBd. Potential circuit roles include body electronics, seat and door modules, climate-control interfaces, lighting controllers, and sensor gateways. The integrated quad-channel architecture can reduce the number of separate single-channel transceivers required on a controller board. Design work should verify supply voltage, pin mapping, bus termination, transceiver enable/control behavior, fault handling, and signal integrity against the complete manufacturer datasheet before layout release. The supplied distributor record identifies a 5 V to 18 V operating feature, while detailed electrical limits, timing values, thermal limits, and pin names were not included in the verified excerpts and therefore remain unconfirmed here. This product page combines the supplied manufacturer, distributor, and cross-reference evidence with practical engineering guidance. It distinguishes verified LIN standards and package information from unavailable specifications, helping designers identify the correct interface function without treating CAN alternatives as pin-compatible replacements.
TJA1029T - 20 kBd LIN 2.2 Automotive Transceiver | NXP
The NXP Semiconductors TJA1029T is a LIN physical-layer transceiver that connects a Local Interconnect Network master or slave protocol controller to the physical vehicle bus. It supports data rates up to 20 kBd, is intended primarily for in-vehicle subnetworks, and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602. The device is supplied in an 8-pin SO package designated 8-SO. A LIN transceiver is a low-speed automotive network interface that converts serial protocol-controller data into a shaped bus signal and converts received bus levels back into logic-compatible data. Within the vehicle-network hierarchy, the TJA1029T belongs to the LIN physical layer, below the LIN protocol controller and above the twisted-pair LIN bus. This division separates frame-level communication and fault management from the electrical interface to the bus. The TJA1029T converts the protocol controller's transmit data stream into an optimized bus signal intended to minimize electromagnetic emissions. Its internal LIN-bus output pull-up and its ability to operate as either a master or slave physical interface suit vehicle subnetwork nodes. The NXP datasheet identifies the TJA1029 as pin-compatible with the TJA1020, TJA1021, TJA1022, TJA1027, and MC33662(B), providing a documented basis for same-footprint replacement evaluation. The device is primarily designed for automotive LIN subnets operating at up to 20 kBd. Typical implementation places the transceiver beside a LIN-compatible microcontroller, connects TXD and RXD to the controller, and connects the LIN pin to the vehicle's LIN bus. In this arrangement, the microcontroller handles protocol frames, addressing, diagnostics, and higher-level vehicle functions, while the TJA1029T performs the physical signaling and bus-interface functions. Because LIN buses commonly operate in harsh automotive environments, the complete transceiver and module design must be validated for the intended voltage, temperature, ESD, emission, and immunity requirements. The supplied verified data does not state the complete electrical limits, thermal ratings, timeout options, or exact pin names, so those details must be confirmed in the manufacturer datasheet and the selected ordering variant before schematic release or PCB sign-off. The main engineering tradeoff is version-specific functionality. Ordering codes such as TJA1029T/20/1J and TJA1029T/2Z appear in distributor records, with the latter identified as including a TXD dominant timeout, but the supplied excerpts do not provide a complete variant matrix. Engineers should therefore match the exact base-device and timeout features required by the LIN controller, firmware, safety analysis, and production BOM rather than selecting only by connector or package. This page consolidates the verified manufacturer statements, distributor availability references, documented pin-compatible alternatives, package information, and practical selection guidance. It also separates verified facts from unprovided electrical details, helping engineers identify valid drop-in candidates while avoiding unsupported assumptions about pricing, pin assignments, lifecycle guarantees, or automotive qualification.
TJA1029T/2Z - 20 kBd LIN 2.2A Transceiver | NXP
The NXP Semiconductors TJA1029T/2Z is an automotive LIN physical-layer transceiver supporting bus speeds up to 20 kBd, LIN 2.0 through LIN 2.2A operation, and SAE J2602 compliance in an 8-pin SOIC package. It interfaces a LIN leader or follower protocol controller with the physical bus and adds a TXD dominant-timeout feature for systems requiring controlled transmitter behavior. A LIN transceiver is a physical-layer interface IC that combines a logic-level transmitter, receiver, bus-driver protection, and LIN bus termination functions. In the vehicle networking hierarchy, LIN connects low-cost nodes for body electronics and in-vehicle subnetworks, while the protocol controller manages frames and scheduling above the transceiver. The TJA1029 therefore bridges a digital controller and the wired LIN network rather than operating as a standalone bus controller. According to NXP product information, the device supports LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, and SAE J2602. Its principal purpose is in-vehicle subnetworks operating at up to 20 kBd. The verified distributor data identifies TJA1029T/2Z as a half-duplex LIN transceiver with TXD dominant timeout, which is useful where the host controller must avoid an indefinitely asserted transmit command. NXP states that TJA1029 is pin-compatible with the TJA1020, TJA1021, TJA1022, and TJA1027. That compatibility creates a controlled upgrade path within the same NXP interface family, although designers must still verify electrical limits, timing, fault behavior, package suffix, and production requirements for the specific replacement. The TJA1021T/20/C from the site MPN list is therefore an important family reference, not an automatically interchangeable part without checking its ordering code. Typical uses include LIN-controlled vehicle body modules, door and seat controllers, climate-control interfaces, lighting modules, sensor gateways, and other low-speed automotive subnetworks. The 20 kBd capability and LIN 2.2A/SAE J2602 positioning align it with established in-vehicle network architectures rather than high-speed body communication buses. The critical design check is the power and bus environment. Use the manufacturer datasheet for the exact VCC range, LIN transceiver operating limits, pin names, external termination, ESD requirements, and thermal limits before layout release. In particular, verify whether the selected SOIC footprint and pin mapping match the exact package variant being assembled.
TJA1040T/CM - 1 MBaud CAN Transceiver | NXP
The NXP Semiconductors TJA1040T/CM is a high-speed CAN transceiver rated for operation up to 1 MBaud and supplied in an 8-pin SO package. It provides differential transmit capability to the physical CAN bus and differential receive capability to a CAN protocol controller, making it an interface between controller-area-network logic and vehicle or industrial bus wiring. A CAN transceiver is a physical-layer interface IC within the broader interface-IC hierarchy. It converts the controller’s digital logic signals into differential bus signaling and converts differential bus levels back into logic-compatible receive signals. The TJA1040 is intended primarily for high-speed passenger-car CAN networks, where robust differential signaling, standby control, and electromagnetic compatibility are important. The verified manufacturer information identifies differential transmission, differential reception, high-speed operation up to 1 MBaud, and standby-mode capability as principal device features. The distributor record identifies the TJA1040T/CM,118 ordering form as an 8-pin SO CAN-bus transceiver. Detailed electrical limits, loop-delay values, bus-fault behavior, and package dimensions were not supplied in the verified extract and therefore require confirmation from the manufacturer datasheet before design release. Typical uses include passenger-vehicle body and powertrain CAN networks, automotive control modules, CAN gateways, and industrial equipment that uses a 5 V CAN physical layer. The transceiver is intended to operate with a compatible CAN controller rather than as a standalone bus controller. Its differential bus interface supports robust communication over cable networks, while the standby function can reduce activity when the node is not communicating. Designers should preserve the pin assignment, supply decoupling, CANH/CANL routing, termination, and common-mode protection described by the manufacturer. The verified source set does not include the complete pinout, absolute maximum ratings, thermal data, or EMC test values, so those details must not be inferred. This page combines official NXP information with distributor records and explicitly marks unavailable parameters rather than estimating them. TJA1040T/CM is a legacy EoL-positioned part according to the supplied migration context. For new designs, engineers should compare it with current NXP or third-party CAN transceivers and verify pin, electrical, lifecycle, and qualification compatibility before treating any replacement as drop-in.
TJA1042AT/0Z - 5Mbps High-Speed CAN Transceiver | NXP
The NXP TJA1042AT/0Z is a high-speed CAN bus transceiver with one transmitter and one receiver, a maximum data rate of 5 Mb/s, and an SOIC-8 surface-mount package. Its 4.5 V to 5.5 V supply range and -40°C to +150°C operating-temperature range make it appropriate for demanding industrial and automotive communication systems. The TJA1042AT/0Z also provides Standby-mode operation, including the bus-wake-up capability described for the TJA1042 family. A CAN transceiver is an interface IC that connects a CAN protocol controller, such as a microcontroller with an integrated CAN controller, to a physical two-wire CAN bus. The transceiver converts the controller's logic-level transmit command into a differential CANH/CANL bus signal and converts the differential bus voltage into a logic-level receive output. Within the product hierarchy, a CAN transceiver belongs to the interface IC class, the CAN interface subclass, and ultimately the broader semiconductor category. The TJA1042AT/0Z provides a data rate of up to 5 Mb/s, one CAN transmitter, one CAN receiver, and a specified operating supply current of 80 mA. Its 4.5 V minimum and 5.5 V maximum supply voltages support conventional 5 V automotive and industrial CAN systems. Standby mode helps reduce system consumption when the bus is inactive, while the family's bus-wake-up behavior supports systems that must detect remote bus activity. The family is designed for high-speed CAN applications in the automotive industry and includes differential transmit and receive capability between a CAN controller and a two-wire bus. NXP describes the TJA1042 as a third-generation high-speed CAN transceiver. Its SOIC-8 construction provides a conventional surface-mount option for PCBs requiring a small, widely supported package, although the actual exposed-pad and soldering details should be confirmed against the manufacturer package drawing. Typical uses include automotive body and powertrain control modules, industrial automation equipment, robotics controllers, building automation gateways, and other embedded systems that exchange data over a CAN bus. In these systems, the controller handles CAN frames and protocol timing, while the TJA1042AT/0Z handles the physical-layer differential signaling. Its 5 Mb/s capability accommodates high-speed CAN traffic, and its -40°C to +150°C specification supports wide environmental ranges. PCB design should preserve the transceiver's supply decoupling, ground connection, controller-interface traces, and CAN bus routing. Place the supply capacitor close to the device and keep the CANH and CANL route as a closely coupled differential pair. The bus conductors require suitable termination, protection, and common-mode considerations; exact resistor and capacitor values are application-dependent and are not specified by the verified source excerpts. This product record combines the verified NXP datasheet information with distributor availability, package details, temperature limits, supply limits, and a bulk pricing schedule as of 2026-10-28. It also distinguishes the TJA1042AT/0Z from related TJA1042 and modern TCAN transceiver options so engineers can assess PCB compatibility and functional differences before selecting a replacement.
TJA1042AT/3/0Z - 5Mbps CAN Transceiver | NXP
The NXP Semiconductors TJA1042AT/3/0Z is a high-speed CAN transceiver with a 5 Mbps maximum data rate, differential CAN bus transmit and receive functions, a 5 V supply, and an 8-pin SOIC package. It provides the physical-layer interface between a CAN protocol controller and a two-wire CAN network, with the /3 version supporting a VIO supply for direct interfacing with 3.3 V or 5 V controller logic. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into the differential CANH and CANL bus signals used by Controller Area Network systems. Within the hierarchy of CAN interface ICs, physical-layer transceivers connect automotive and industrial network controllers to the bus while adding bus protection, standby behavior, and standardized digital interfaces. The TJA1042 family is specifically designed for high-speed automotive CAN networks. Principal features include a maximum CAN data rate of 5 Mbps, one-transceiver one-receiver organization, differential bus output, low-power Standby mode, and VIO support in the /3 version. The separate VIO rail allows the controller-facing pins to operate from a lower voltage while CANH, CANL, and the transceiver core use the 5 V supply. The Arrow product listing identifies the device as an automotive AEC-Q100 8-pin SOIC transceiver. The TJA1042AT/3/0Z uses pin 5 as VIO rather than the SPLIT common-mode stabilization function found on the TJA1042T version. This distinction is important during replacement because the two suffix families do not have identical pin 5 functions. The /3 device also provides bus wake-up capability and passive behavior when unpowered, characteristics that support low-power automotive networking and robust bus integration. Typical applications include automotive body and chassis control modules, powertrain and gateway controllers, industrial CAN equipment, robotics, and embedded transport systems. It is particularly suitable where a microcontroller or dedicated CAN controller requires a 5 Mbps physical interface while its digital I/O operates at 3.3 V. The low-power Standby function helps reduce current consumption when the node is not actively communicating. When laying out a circuit, place the transceiver close to the CANH and CANL connector, keep the bus traces short and matched, and provide the decoupling and common-mode components recommended by the NXP TJA1042 manufacturer datasheet. Verify that VIO is connected correctly on the /3 version and that PCB exposure, automotive qualification, and temperature requirements match the intended installation. This page combines the NXP manufacturer datasheet, product listings, verified drop-in candidates, interface comparisons, and practical PCB guidance. It helps engineers identify the correct /3 variant, distinguish VIO from SPLIT implementations, and plan a CAN transceiver layout without relying on a generic SOIC-8 pinout.

TJA1042T/1J - High-Speed CAN Transceiver | NXP | Automotive
The NXP TJA1042T/1J is a high-speed CAN transceiver with standby mode, providing the physical-layer interface between a CAN protocol controller and a differential two-wire CAN bus. The device is packaged as an 8-pin SOIC and is identified by DigiKey as a 1/1 half CAN-bus transceiver. The verified NXP product page describes it as a high-speed CAN transceiver with standby mode, while the manufacturer datasheet states that it supplies differential transmit and receive capability for automotive CAN systems. A CAN transceiver is an interface IC that converts logic-level TXD and RXD signals into the dominant and recessive voltage levels carried by a CAN bus. It also places the bus-side driver and receiver between the controller and the physical network, helping the controller communicate over a robust multi-node differential bus. The TJA1042 family belongs to the broader CAN transceiver, communication interface, interface IC, and semiconductor hierarchy. The key verified feature set is high-speed CAN operation, differential transmit and receive, standby operation, 8-pin SOIC packaging, and automotive-oriented application positioning. The standby function is useful when a node must reduce activity while retaining the CAN interface. The exact maximum data rate, supply range, loop delay, bus fault behavior, thermal limits, and electrical thresholds are not present in the supplied verified excerpts, so those values must be confirmed from the complete manufacturer datasheet before design release. The TJA1042 is intended for automotive electronic control units, body controllers, powertrain controllers, gateway modules, instrument clusters, and other embedded systems that use a CAN protocol controller. In a typical circuit, the MCU CAN controller connects to TXD and RXD, while CANH and CANL connect to the external bus through the board's approved network interface and termination arrangement. The transceiver is the boundary between digital controller signaling and the differential physical bus. Designers should verify the exact NXP ordering code, supply voltage, transceiver mode timing, bus termination, common-mode environment, loop delay, and external-component recommendations against the complete TJA1042 datasheet. Because the supplied web data does not expose a complete pin-level table, pricing schedule, compliance declaration, or lifecycle statement, those items are marked as needing verification rather than inferred. The TJA1042T/1J is best evaluated by engineers who need a standby-capable, high-speed CAN physical-layer device in an SOIC footprint.
TJA1042T/1U - High-Speed CAN Transceiver | NXP | SOIC-8
The NXP Semiconductors TJA1042T/1U is a high-speed CAN transceiver with standby mode, packaged in an 8-pin SOIC. It provides the physical-layer interface between a CAN protocol controller and a differential two-wire CAN bus. The device supports the transmit, receive, standby, split and bus-fault functions expected from a high-speed automotive CAN transceiver, while its SOIC-8 format supports conventional surface-mount PCB assembly. A CAN transceiver is an interface IC within the broader Controller Area Network hierarchy. It converts logic-level TXD and RXD signals from a CAN controller into the dominant and recessive differential levels carried by CANH and CANL. Conversely, it converts the differential bus voltage into a logic-compatible receive signal. This physical-layer function allows a microcontroller or dedicated CAN controller to communicate reliably with other nodes on a shared network. The TJA1042T/1U differentiates itself through its standby operating mode and split functionality. Standby mode lets the node reduce activity when it is not required to participate fully in bus communication. The split function is associated with stabilizing recessive bus behavior and can be important in systems containing more than one CAN node. NXP markets the TJA1042T family for high-speed CAN applications in the automotive industry. The TJA1042T/1U is identified as an NRND product on the official NXP product page. NRND means the product is not recommended for new designs, so engineers should evaluate the lifecycle position and any successor named by NXP before committing a new production platform to this MPN. Existing designs may still use the part, but procurement and long-term availability require confirmation from authorized distributors. Typical uses include distributed automotive control modules, body electronics, electric vehicle subsystems, industrial CAN gateways, sensor nodes and engine or transmission control units. The differential bus interface lets these systems exchange data reliably over distances and wiring arrangements that would be unsuitable for ordinary single-ended digital signaling. Local CAN-controller I/O voltage compatibility must also be checked during design review. PCB implementation requires care around the CANH and CANL connections. The two bus conductors should follow the impedance and routing guidance in the manufacturer datasheet, with a common-mode choke or split capacitor used only when the reference network requires it. Decoupling should be placed close to the supply pins, and unused device functions must be connected exactly as specified in the datasheet rather than according to generic transceiver schematics. This page consolidates the verified NXP product information, distributor package identification, sourcing context, lifecycle status and practical design guidance. It distinguishes documented facts from values that require confirmation from the current manufacturer datasheet, helping engineers evaluate the TJA1042T/1U without treating incomplete distributor snippets as complete electrical specifications.
TJA1042T/3/1J - High-Speed CAN Transceiver w/ Standby, SOIC-8 | NXP
The NXP TJA1042T/3/1J is a high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and a two-wire CAN bus, supplied in an 8-pin SOIC package with a maximum data rate of 1 Mbit/s. It operates from a 4.5 V to 5.5 V VCC supply and supports direct interfacing to microcontrollers with supply voltages as low as 3 V through a dedicated VIO pin (variant /3). The device features low-current Standby mode with bus wake-up capability and ideal passive behavior to the CAN bus when VCC is off. A CAN transceiver (also called a CAN bus transceiver or CAN physical layer device) is a protocol-bridge IC that converts the differential digital signaling on a CAN bus into the single-ended TX/RX logic levels expected by a microcontroller's CAN protocol controller. CAN transceivers sit one layer below the CAN data link layer in the OSI model and are essential for any automotive, industrial, or embedded system that communicates over the Controller Area Network standard (ISO 11898). Without a transceiver the MCU's CAN controller cannot drive or receive the bus. Key features include excellent electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance, an SPLIT-pin-free /3 variant with a VIO reference for 3.3 V MCUs, and pin compatibility with the classic TJA1040, PCA82C250, and PCA82C251. The transceiver supports bus wake-up patterns, thermal shutdown, a dominant time-out that prevents bus lockup if the controller fails, and an unpowered bus node that does not disturb the network. The TJA1042T/3/1J also provides a low-current Standby mode in which the bus is continuously monitored for wake-up frames. Internally the device uses a differential driver with slope control to minimize EMI, very-low-drop receiver comparators, and an integrated VIO reference that allows the logic I/O domain of the chip to match the host MCU's supply. Compared to its predecessor TJA1040, the TJA1042 reduces quiescent current, improves ESD to at least 6 kV HBM, and adds the VIO pin to decouple digital I/O levels from VCC for 3.3 V microcontrollers. Typical applications include automotive body and chassis ECUs, industrial CANopen and DeviceNet nodes, elevator controllers, building automation gateways, and any CAN node that must interface to a 3.3 V microcontroller without level shifters. The part is widely used as the physical-layer upgrade for designs that previously used TJA1040, PCA82C250, or PCA82C251. When designing with this part, place a 100 nF decoupling capacitor as close as possible to the VCC pin and a 100 nF cap on VIO; add a common-mode choke and split termination (60 ohm + 5.6 nF at each end) on bus lines operating above 500 kbit/s in noisy environments. Tie the STBY pin high for Normal mode and monitor CANH/CANL for short-to-ground or short-to-VCC conditions. The /3 variant replaces the SPLIT pin of the original TJA1042T with a VIO pin, so confirm that the PCB land pattern matches pin 5 = VIO. This page synthesizes distributor pricing, drop-in alternatives from the same TJA1042 family and competitor cross-references such as TCAN1042, plus practical design notes not found in the manufacturer datasheet.
TJA1042T/3/1U - 5 Mbit/s CAN FD Transceiver | NXP
NXP TJA1042T/3/1U is a high-speed CAN transceiver with Standby mode, providing an interface between a CAN protocol controller and a two-wire CAN bus. The device supports reliable CAN and CAN FD communication at data rates up to 5 Mbit/s and is packaged in an 8-pin SOIC-style package. Its automotive temperature grade and 3 V microcontroller interface capability suit vehicle networking systems that require low-power standby operation. A CAN transceiver is the physical-layer interface within a Controller Area Network communication hierarchy. It converts logic-level TXD and RXD signals into balanced differential bus levels on CANH and CANL, while also providing bus dominance, recessive-state detection, and controller-side logic interfacing. The TJA1042 therefore belongs to the CAN physical-layer transceiver, interface IC, and automotive communication semiconductor categories. The TJA1042T/3/1U supports data rates up to 5 Mbit/s, includes a low-power Standby mode, and provides improved electromagnetic compatibility and electrostatic-discharge performance. Its /3 variant is intended for direct interfacing with microcontrollers operating from supply voltages down to 3 V. Pin 5 provides the VIO function instead of the SPLIT function found on certain other TJA1042 variants, making the ordering-code distinction important during PCB design and replacement planning. The transceiver integrates CAN bus driver and receiver functions with controller-facing logic inputs and outputs. VIO supports compatible microcontroller interfacing, while RXD reports the received bus state to the CAN controller. CANL and CANH provide the differential physical bus connection, and VCC supplies the transceiver. This integration allows a CAN controller to communicate over a robust two-wire bus without implementing the bus-line driver and receiver externally. Typical uses include automotive body and comfort modules, powertrain controllers, electric-vehicle control units, diagnostic gateways, industrial CAN equipment, and CAN FD nodes. The 5 Mbit/s capability is particularly useful where the network carries larger payloads or enables CAN FD data-phase communication. Standby mode supports systems that need to retain low-power behavior while reducing activity when the node is not communicating. When designing around the TJA1042T/3/1U, verify that the PCB footprint accommodates the 8-pin SOIC package and that the controller supply level matches the VIO arrangement of the /3 variant. CAN bus layouts should follow the routing and termination guidance in the manufacturer datasheet, including correct 120-ohm termination only at the physical ends of the bus. This product overview combines the verified NXP family characteristics with application guidance, pin-role clarification, practical layout considerations, and qualified replacement comparisons. It is intended to help engineers distinguish the TJA1042T/3/1U from related SOIC-8 CAN transceivers whose logic, supply, standby, or bus-behavior details differ.
TJA1042TK/3/1J - 5 Mbit/s CAN FD Transceiver | NXP
NXP Semiconductors TJA1042TK/3/1J is a high-speed Controller Area Network transceiver with a maximum supported data rate of 5 Mbit/s, CAN FD compatibility, and a low-power Standby mode. The device is packaged in an 8-pin HVSON package measuring 3 mm by 3 mm and interfaces a CAN protocol controller with a physical two-wire CAN bus. A CAN transceiver is an interface IC that converts logic-level signals from a CAN controller into the differential dominant and recessive states carried by a CAN bus. It also converts received bus states into signals the controller can interpret. The TJA1042 family belongs to the CAN transceiver hierarchy within interface ICs, semiconductors, and automotive communication electronics. The TJA1042 supports reliable CAN and CAN FD communication up to 5 Mbit/s. Its Standby mode provides a low-power operating state, while the 3.3 V VIO connection supports communication with CAN controllers operating at that logic level. The manufacturer identifies improved electromagnetic compatibility and electrostatic-discharge performance as principal benefits of the family. The TJA1042TK/3/1J ordering code identifies the 8-HVSON 3 mm by 3 mm package configuration and a 3.3 V VIO variant. The package offers a compact surface-mount implementation for automotive electronics, but its exposed-pad construction and limited thermal path require careful PCB layout. CAN bus traces should be routed as a controlled differential pair with appropriate termination and common-mode considerations. Typical uses include automotive CAN FD gateways, body and comfort controllers, electric-vehicle subsystems, industrial CAN equipment, and battery-management systems with 3.3 V CAN controllers. The combination of 5 Mbit/s operation, CAN FD support, and Standby mode is useful where high communication bandwidth and reduced inactive-state consumption are both important. Use the manufacturer pin-description table when assigning PCB tracks and land patterns, and confirm the controller voltage, bus termination, transceiver supply levels, and standby-control polarity before releasing a board layout. The small HVSON package also requires adequate copper around the thermal pad and controlled assembly-planarity conditions. This page organizes the TJA1042TK/3/1J specifications, verified source links, application guidance, engineering design notes, and compatibility considerations to support faster component selection and PCB implementation.
TJA1043AT/0Z - 5 Mbps CAN Transceiver | NXP | Automotive
The NXP TJA1043AT/0Z is a high-speed CAN transceiver supporting data rates up to 5 Mbps in a 14-pin SOIC package. It operates from a 4.5 V to 5.5 V supply and provides Normal, Sleep, and Standby operating modes for power-managed automotive and industrial CAN networks. The part is identified as an AEC-Q100 automotive-grade device and is supplied in tape-and-reel packaging. A CAN transceiver is the physical-layer interface between a host controller and a Controller Area Network bus. The CAN standard assigns the physical signaling, termination, dominant and recessive states, and bus fault behavior that allow nodes to communicate reliably over a wired network. A CAN interface IC therefore bridges digital controller signals and the differential CANH and CANL bus conductors. The TJA1043AT/0Z family is designed for high-speed communication while adding fail-safe and diagnostic capabilities intended to improve system reliability. Its supported modes give a host controller opportunities to reduce power use when communication is not required. The verified product data specifies 5 Mbps operation, a 4.5 V to 5.5 V DC operating range, Normal/Sleep/Standby modes, AEC-Q100 qualification, and a 14-pin SOIC package. The TJA1043 product family combines a CAN transmitter, CAN receiver, bus-driver enable control, and low-power management in one interface device. This integration reduces the number of discrete components required around a CAN controller and centralizes bus-domain behavior. Because CAN bus reliability depends on correct termination and layout, the transceiver remains only one element of the complete network design. Typical uses include automotive body and comfort modules, industrial automation equipment, engine controllers, gateways, sensors, and embedded control systems. A controller such as the site's ISO1500DBQ can provide an isolated interface layer, while the TJA1043AT/0Z handles the non-isolated physical CAN connection. Its 5 Mbps capability supports communication-intensive vehicle networks and industrial equipment. Designers should verify the complete pinout against the current NXP datasheet before layout because the supplied verified data confirms the 14-pin package but does not expose individual pin assignments. CANH and CANL routing also requires controlled impedance, a common-ground strategy, correct 120 ohm termination at the physical bus endpoints, and protection appropriate for the target environment. This product page consolidates current distributor availability, the confirmed electrical envelope, automotive qualification, packaging information, and practical interface-selection guidance. It also distinguishes verified drop-in candidates from broader functional alternatives so engineers can assess PCB reuse, power-mode behavior, and bus-system compatibility before committing to a replacement.
TJA1043T - High-Speed CAN Transceiver, 1Mbps, SO-14 | NXP
The NXP TJA1043T is a high-speed Controller Area Network (CAN) transceiver that provides the physical interface between a CAN protocol controller and a differential two-wire CAN bus, housed in a 14-pin SO (SOIC-14) package. It supports data rates up to 1 Mbps across the ISO 11898-2 / ISO 11898-5 compliant physical layer, and operates from a 5 V supply with very low standby and sleep-mode quiescent currents for ECU sleep-current budgets. The device provides differential transmit and receive capability and integrates dominant-timeout, bus-failure diagnostics, and thermal protection. A CAN transceiver (sometimes called a CAN physical layer or CAN PHY) is the analog interface between a digital CAN protocol controller (typically inside an MCU) and the differential CANH/CANL bus wires that carry data across a vehicle network. It belongs to the broader hierarchy of bus transceivers -> interface ICs -> wired communication ICs. Automotive ECUs (Electronic Control Units) require a certified transceiver that meets ISO 11898 EMC and ESD specifications; the TJA1043 family is a third-generation NXP design widely used in body, chassis, and powertrain CAN nodes. Key features include 1 Mbps maximum bit rate, ±8 kV HBM ESD on bus pins (per NXP datasheet figures), very low quiescent current in Sleep mode (typically a few microamps), an SPLIT pin for bus biasing when the bus is off, and three operating modes (Normal, Standby, Sleep) selectable via the EN and STBN pins. The IC operates across -40 °C to +125 °C ambient and is qualified to the automotive quality flow. Internally the TJA1043T uses a bipolar-CMOS-DMOS (BCD) process that combines 5 V analog drive strength on the bus with low-power digital logic. The receiver includes a wide common-mode range for excellent EMC immunity, and the transmitter incorporates slew-rate control to limit EMI on unshielded bus segments. Typical applications include automotive body control modules, gateway ECUs, chassis controllers, infotainment CAN nodes, and industrial CAN-FD ready nodes that need backward-compatible high-speed CAN. The wide common-mode range also makes it suitable for 12 V and 24 V battery systems in trucks and off-road equipment. When designing with this part, place a 100 nF decoupling capacitor close to VCC and respect the SPLIT-pin biasing network shown in the datasheet typical application. Verify bus termination (120 Ω at each end) and dominant-timeout behaviour when using a permanently dominant TXD input. This page synthesizes distributor pricing, drop-in alternative guidance, and practical design notes that complement the manufacturer datasheet and accelerate your component selection.
TJA1043T-1J - High-Speed CAN Transceiver, 5Mbit/s | NXP
The NXP TJA1043T-1J is a third-generation high-speed Controller Area Network (CAN) transceiver providing the physical interface between a CAN protocol controller and a differential two-wire CAN bus, supporting data rates up to 5 Mbit/s in a 14-pin SOIC package. It features VIO supply pin for direct interfacing with 3.3V microcontrollers, SPLIT voltage output for bus biasing stabilization, dedicated wake-up input, standby control (STBN), and an enable pin. The part is qualified for automotive networks and conforms to ISO 11898-2:2024 high-speed CAN physical layer requirements. A CAN transceiver is an interface IC that translates single-ended logic-level TXD/RXD signals from a microcontroller into the differential voltage signaling required on the CANH and CANL bus wires, while simultaneously protecting the controller from bus-side ESD and EMC events. Within the broader hierarchy, the TJA1043 belongs to the class of bus transceivers (also called physical-layer devices or PHYs), which sit between the data-link-layer CAN controller and the physical CAN bus medium in an in-vehicle network. Key features include very low quiescent current consumption in standby and sleep modes, passive bus behavior when supply is off (no reverse current into the bus), integrated thermal shutdown, and bus-pin ESD protection up to ±8 kV HBM. The VIO pin allows the logic supply to be tied directly to a 3.3V microcontroller without level shifters, simplifying mixed-voltage ECU designs. Typical applications include automotive body and powertrain ECUs, gateway modules, ADAS sensor nodes, industrial CAN automation networks, and CAN-FD backbone segments where bus termination biasing and EMC robustness are critical. The SPLIT pin stabilizes the recessive bus common-mode voltage, especially important in networks with multiple unpowered nodes. When designing with this device, keep the SPLIT pin terminated through a capacitor to ground per the datasheet reference design, and ensure the VIO and VCC rails are sequenced correctly to avoid latch-up during cold-crank events in 12V automotive systems.
