Product details
Overview
TCAN1042HVDR from Texas Instruments is a fault-protected high-speed CAN FD transceiver compliant with ISO 11898-2:2016 and ISO 11898-5:2007, supporting up to 2 Mbps data rates, ±70 V bus fault protection, and dual-supply I/O level shifting (VIO/VCC). It operates across –55°C to 150°C junction temperature and delivers 110 ns typical loop delay for timing-critical automotive and industrial CAN networks.
For engineers reviewing the TCAN1042HVDR datasheet, TCAN1042HVDR pinout, TCAN1042HVDR application, or TCAN1042HVDR equivalent, this page provides verified functional specifications, SOIC-8 package details, real-world use cases in heavy machinery and industrial automation, and validated alternative parts with documented technical differences.
Technical Context
The TCAN1042HVDR implements a robust differential driver/receiver pair with integrated dominant timeout, thermal shutdown, and undervoltage protection on both VCC and VIO supplies. Its H-variant architecture enables ±70 V bus fault tolerance - exceeding standard ±58 V - while maintaining full compatibility with classic CAN and CAN FD protocols.
It features symmetrical propagation delays (tpHR = 75 ns, tpLD = 55 ns), fast mode transition (tMODE = 9 µs typ), and receiver common-mode range of ±30 V. The dual-supply design (VCC = 4.5–5.5 V, VIO = 3–5.5 V) allows seamless interfacing with 3.3 V or 5 V MCUs without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 2 Mbps CAN FD - supports flexible data-rate networks without requiring G-suffix 5 Mbps variants. |
| Bus Fault Protection | ±70 V - enables operation in harsh environments like ISOBUS tractors or industrial power systems where voltage transients exceed ±58 V. |
| Loop Delay | 110 ns typical - ensures tight timing margins in high-speed CAN FD nodes with minimal signal skew. |
| Common-Mode Range | ±30 V - maintains reliable reception under severe ground offset conditions in distributed control systems. |
| Supply Voltages | VCC = 4.5–5.5 V; VIO = 3–5.5 V - allows direct connection to 3.3 V microcontrollers while powering transceiver core from 5 V rail. |
| ESD Protection | HBM ±16 kV on CANH/CANL - eliminates need for external TVS diodes in many automotive ECU designs. |
| Junction Temp | –55°C to +150°C - qualified for under-hood and motor-drive applications without derating. |
Pinout & Package
TCAN1042HVDR is supplied in an 8-pin SOIC (D) package (4.90 mm × 3.91 mm) with gull-wing leads, optimized for automated optical inspection and reflow soldering in industrial PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Digital input | MCU transmit data input; LOW = dominant bus state, HIGH = recessive; accepts 3.3 V or 5 V logic levels. |
| 2 - GND | Ground reference | Primary return path for VCC, VIO, and bus signals; must be low-impedance for noise immunity. |
| 3 - VCC | Power supply | 5 V transceiver core supply; UVLO triggers at 3.8–4.4 V to prevent undefined bus behavior during brownout. |
| 4 - RXD | Digital output | Receiver output driven to VIO level - matches MCU I/O voltage regardless of VCC, enabling mixed-voltage systems. |
| 5 - VIO | I/O level-shift supply | 3.3 V or 5 V reference for TXD input thresholds and RXD output level - required for V-suffix devices like TCAN1042HVDR. |
| 6 - CANL | Bus I/O | Low-side CAN bus terminal; forms differential pair with CANH; withstands ±70 V faults. |
| 7 - CANH | Bus I/O | High-side CAN bus terminal; pairs with CANL; integrated fault protection prevents latch-up during load dump. |
| 8 - STB | Digital input | Standby mode enable (active-high); places transceiver in ultra-low-power state (<5 µA) with remote wake capability. |
Key Features
| Feature | Design Value |
|---|---|
| Fault-tolerant bus interface | ±70 V bus fault protection - sustains operation during battery reverse-connection or load-dump events in 24 V vehicle systems. |
| Dual-supply I/O level shifting | VIO pin enables independent 3.3 V/5 V logic interfacing - eliminates external level translators in mixed-voltage CAN nodes. |
| Glitch-free power sequencing | Passive bus and logic terminals when unpowered - prevents bus contention or false wakeups during MCU boot or power-down. |
| Thermal shutdown with hysteresis | Triggers at 170°C with 5°C hysteresis - protects against sustained overloads in enclosed enclosures without system-level intervention. |
| Driver dominant time-out | 1.2–3.8 ms timeout - prevents bus lockup if TXD remains LOW indefinitely, ensuring network recovery without host intervention. |
Applications
| Heavy Machinery ISOBUS | Industrial Drive Systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN1042HDR | No VIO pin; RXD output referenced to VCC only - requires matching 5 V MCU I/O. | Limited to single-supply 5 V systems; cannot interface directly with 3.3 V microcontrollers. | Select when cost-sensitive 5 V-only designs eliminate need for level shifting and reduce BOM count. |
| SN65HVD256DR | Lower bus fault protection (±40 V); no VIO pin; supports only classic CAN (1 Mbps max). | Not suitable for ISO 11783 ISOBUS or CAN FD networks; lacks thermal shutdown and dominant timeout. | Choose only for legacy 1 Mbps CAN nodes where extended fault tolerance and FD features are unnecessary. |
Compared with TCAN1042HDR and SN65HVD256DR, TCAN1042HVDR uniquely combines ±70 V fault protection, dual-supply I/O flexibility, and full CAN FD support - making it the only option among the three qualified for safety-critical, mixed-voltage, high-transient industrial and off-road vehicle applications.

FAQ
What is the bus fault protection rating of TCAN1042HVDR?
The TCAN1042HVDR provides ±70 V bus fault protection on CANH and CANL terminals - a key differentiator from standard ±58 V variants. This rating is explicitly specified in the device comparison table and absolute maximum ratings section of the datasheet, enabling reliable operation during 24 V system load dumps and reverse-battery conditions commonly found in off-road and agricultural vehicles.
Does TCAN1042HVDR support CAN FD data rates above 2 Mbps?
No, TCAN1042HVDR supports up to 2 Mbps CAN FD - consistent with all non-G-suffix devices in the TCAN1042 family. Devices with the "G" suffix (e.g., TCAN1042HG) are required for 5 Mbps operation. The datasheet clearly states that only G-variants support higher data rates, and TCAN1042HVDR's functional description and device comparison table confirm its 2 Mbps limit.
How does the VIO pin function in TCAN1042HVDR?
In TCAN1042HVDR, the VIO pin (Pin 5) supplies the reference voltage for TXD input thresholds and RXD output logic levels - allowing independent 3.3 V or 5 V MCU interfacing while VCC powers the transceiver core. This dual-supply architecture eliminates external level shifters and is confirmed in the Pin Functions table, electrical characteristics, and functional block diagram of the official datasheet.
What is the typical loop delay of TCAN1042HVDR and why does it matter?
The TCAN1042HVDR has a typical loop delay of 110 ns (tPROP(LOOP2)), measured from TXD input to RXD output in dominant-to-recessive transitions. This value is critical for timing budget allocation in high-speed CAN FD networks - especially in multi-node systems where cumulative delay affects bit sampling accuracy and synchronization margins.
Is TCAN1042HVDR compatible with ISO 11898-2:2016 and ISO 11898-5:2007?
Yes, TCAN1042HVDR explicitly meets both ISO 11898-2:2016 (high-speed CAN physical layer) and ISO 11898-5:2007 (fault-tolerant CAN for road vehicles) standards. This compliance is stated in the "Features" section and reinforced in the "Description" and "Device Information" sections of the official Texas Instruments datasheet SLLSES7D.
