Product details
Overview
TCAN1042GVDRBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive CAN FD transceiver supporting 2 Mbps data rates, ±58 V bus fault protection, and dual-supply I/O level shifting (VCC/VIO). It features 110 ns typical loop delay, integrated driver dominant time-out, thermal shutdown, and operates across –55°C to 150°C junction temperature for engine control unit (ECU) and ADAS domain controller interfaces.
For engineers reviewing the TCAN1042GVDRBRQ1 datasheet, TCAN1042GVDRBRQ1 pinout, TCAN1042GVDRBRQ1 application, or TCAN1042GVDRBRQ1 equivalent, key selection criteria include its VIO-enabled 3.3 V/5 V MCU interface compatibility, ISO 11898-2:2016 compliance, fault-protected bus terminals, and VSON (3.0 mm × 3.0 mm) package with AOI-optimized leadless construction.
Technical Context
The TCAN1042GVDRBRQ1 implements a high-speed differential CAN physical layer transceiver with integrated TXD-to-CANH/CANL driver and CANH/CANL-to-RXD receiver. Its architecture includes independent VCC (5 V) and VIO (3–5.5 V) supplies enabling logic-level translation between 3.3 V microcontrollers and 5 V CAN bus signaling.
Functional safety support includes documentation for ISO 26262 ASIL-B system integration, while Turbo CAN operation delivers symmetrical propagation delays and fast loop times-critical for timing-critical CAN FD networks operating up to 2 Mbps in loaded topologies without common-mode chokes per SAE J2962-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | 2 Mbps CAN FD (not 5 Mbps - "G" suffix required for 5 Mbps; TCAN1042GVDRBRQ1 lacks "G") |
| Bus Fault Protection | ±58 V on CANH/CANL - enables robust operation in 12 V/24 V automotive systems with load dump or reverse battery events |
| VIO Supply Range | 3.0 V to 5.5 V - supports direct interfacing with 3.3 V MCUs while maintaining 5 V CAN bus drive capability |
| Loop Delay | 110 ns typical - ensures tight timing margin for high-speed sampling in CAN FD receivers |
| Operating Junction Temp | –55°C to +150°C - qualified for under-hood placement including transmission control modules and battery management systems |
| ESD Protection | ±15 kV HBM on CANH/CANL - exceeds IEC 61000-4-2 Level 4 for system-level ESD immunity without external protection |
| Standby Current | 0.5–5 µA - enables ultra-low-power wake-on-CAN functionality in always-on vehicle networks |
Pinout & Package
TCAN1042GVDRBRQ1 uses the VSON-8 (DRB) package: 3.0 mm × 3.0 mm, leadless, thermally enhanced with exposed thermal pad (recommended to connect to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Digital input | CMOS-level transmit data input; accepts 0.3×VIO / 0.7×VIO thresholds when VIO is active |
| 2 - RXD | Digital output | CMOS-level receive data output driven to VIO voltage - matches MCU I/O domain |
| 3 - GND | Ground reference | Primary ground return for VCC, VIO, and bus circuitry; thermal pad connection point |
| 4 - VCC | Power supply | 5 V transceiver core supply - powers driver/receiver analog circuitry and internal biasing |
| 5 - VIO | Power supply | I/O level-shifting supply - sets TXD input thresholds and RXD output voltage (3–5.5 V) |
| 6 - CANL | Bus I/O | Differential low-side CAN bus terminal - withstands ±58 V faults and supports ISO 11898-2 DC characteristics |
| 7 - CANH | Bus I/O | Differential high-side CAN bus terminal - paired with CANL for 2.5 V nominal recessive and >2.75 V dominant swing |
| 8 - STB | Digital input | Active-high standby mode control - places transceiver in ultra-low-power state with glitch-free bus/RXD behavior |
Key Features
| Feature | Design Value |
|---|---|
| I/O Level Shifting | VIO supply enables seamless interface between 3.3 V MCUs and 5 V CAN bus - eliminates external level translators |
| Fault-Protected Bus Terminals | ±58 V tolerance on CANH/CANL - sustains operation during battery reversal, load dump, and jump-start conditions |
| Glitch-Free Power Sequencing | Passive bus and logic terminals when unpowered - prevents backfeeding and ensures safe power-up/down transitions |
| Driver Dominant Time-Out | Prevents bus lockup by forcing recessive state after ~100 µs of continuous dominant TXD - supports data rates down to 10 kbps |
| Thermal Shutdown Protection | Triggers at 170°C junction temperature with 5°C hysteresis - protects against sustained overcurrent or ambient overheating |
Applications
| Engine Control Unit (ECU) | Advanced Driver Assistance Systems (ADAS) Domain Controller |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN1042HGVDRBRQ1 | ±70 V bus fault protection (vs. ±58 V); same VIO, VSON-8, and 2 Mbps capability | Better suited for 24 V commercial vehicle systems with higher transient risk (e.g., mining trucks, buses) | Select when system-level testing requires extended bus fault margin beyond ±58 V |
| SN65HVD256DR | Classic CAN only (1 Mbps max); no VIO supply; SOIC-8 package; no CAN FD or thermal shutdown | Limited to legacy CAN networks without FD data rate or functional safety requirements | Choose only for cost-sensitive, non-automotive, low-speed CAN designs where FD and AEC-Q100 are not required |
Compared with TCAN1042GVDRBRQ1, TCAN1042HGVDRBRQ1 offers higher bus fault tolerance but identical pinout and feature set, whereas SN65HVD256DR lacks CAN FD, VIO, thermal protection, and automotive qualification - making it unsuitable for new AEC-Q100 designs requiring 2 Mbps or functional safety support.

FAQ
What is the maximum data rate supported by the TCAN1042GVDRBRQ1?
The TCAN1042GVDRBRQ1 supports up to 2 Mbps CAN FD operation. Although some variants in the TCAN1042-Q1 family (e.g., those with "G" suffix) support 5 Mbps, the TCAN1042GVDRBRQ1 does not include the "G" suffix and is rated for 2 Mbps per TI's official datasheet and device comparison table.
Does the TCAN1042GVDRBRQ1 require both VCC and VIO supplies to operate?
Yes - the TCAN1042GVDRBRQ1 requires both VCC (5 V) for the transceiver core and VIO (3–5.5 V) for I/O level shifting. When VIO is applied, TXD input thresholds and RXD output levels track VIO; if VIO is omitted, the device defaults to 5 V-only operation and is not functional in VIO-dependent configurations.
What package type is used for the TCAN1042GVDRBRQ1?
The TCAN1042GVDRBRQ1 uses the VSON-8 (DRB) package: 3.0 mm × 3.0 mm, leadless, with an exposed thermal pad. This package is optimized for automated optical inspection (AOI) and provides superior thermal performance compared to SOIC-8, with RθJA = 48.3°C/W under high-K board conditions.
How does the TCAN1042GVDRBRQ1 handle undervoltage conditions on VCC and VIO?
The TCAN1042GVDRBRQ1 includes undervoltage protection on both supplies: VCC UVLO triggers at 4.2–4.4 V (rising) with 200 mV hysteresis, and VIO UVLO activates at 1.3–2.75 V (rising) with 80 mV hysteresis. During undervoltage, the device enters protected mode - disabling driver outputs and placing RXD in high-impedance state to prevent bus corruption.
Is the TCAN1042GVDRBRQ1 pin-compatible with other devices in the TCAN1042-Q1 family?
Yes - all TCAN1042-Q1 family members, including TCAN1042GVDRBRQ1, share identical pinouts across SOIC-8 (D) and VSON-8 (DRB) packages. Pin functions (TXD, RXD, VCC, VIO, CANH, CANL, GND, STB) are consistent; only electrical differences (e.g., bus fault rating, presence of "G" or "H") vary between variants.
