Product details
Overview
TCAN1042VDRBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive CAN FD transceiver supporting 2 Mbps data rates, ±58 V bus fault protection, and dual-supply I/O level shifting (VCC/VIO). It operates across –55°C to 150°C junction temperature and features 110 ns typical loop delay, ideal for high-reliability vehicle network nodes in powertrain and body control modules.
For engineers reviewing the TCAN1042VDRBRQ1 datasheet, TCAN1042VDRBRQ1 pinout, TCAN1042VDRBRQ1 application, or TCAN1042VDRBRQ1 equivalent, key selection criteria include its VIO-enabled 3.3 V/5 V MCU interface compatibility, fault-protected CANH/CANL terminals, standby mode with remote wake, and SOIC-8/VSON-8 package options verified per ISO 11898-2:2016 and SAE J2962-2.
Technical Context
The TCAN1042VDRBRQ1 implements a differential driver/receiver pair compliant with ISO 11898-2:2016 high-speed CAN physical layer, with integrated dominant time-out (DTO) limiting TXD low pulses to ≥100 µs and thermal shutdown at 170°C. Its VIO pin enables independent logic-level translation for RXD output and TXD input thresholds, decoupling MCU I/O voltage from VCC.
It supports functional safety system design via documented failure modes and diagnostic coverage metrics, and achieves robust EMC performance-meeting IEC 62228-3 up to 500 kbps and SAE J2962-2 without common-mode chokes-through symmetrical propagation delays and optimized bus termination behavior.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN1042HDRBRQ1 | ±70 V bus fault protection (H variant); same VIO, 2 Mbps, VSON-8 | Required for higher-voltage battery architectures (e.g., 48 V mild hybrid systems) | Select when bus fault margin >±58 V is mandated by system-level safety analysis |
| TCAN1042GVDQ1 | 5 Mbps CAN FD support (G variant); SOIC-8 package; VIO enabled | Suitable for high-bandwidth firmware updates or time-sensitive control loops | Choose only if 5 Mbps data rate is required - not drop-in compatible due to different switching characteristics |
Compared with TCAN1042VDRBRQ1, TCAN1042HDRBRQ1 provides higher bus fault tolerance but identical I/O flexibility and package, while TCAN1042GVDQ1 enables faster data rates in SOIC-8 at the cost of reduced EMC margin at 5 Mbps and no VSON option.

FAQ
What is the maximum data rate supported by TCAN1042VDRBRQ1?
The TCAN1042VDRBRQ1 supports up to 2 Mbps CAN FD data rates. It does not support 5 Mbps - that capability requires the "G" suffix variant (e.g., TCAN1042GVDRBRQ1). This limitation is defined in the device's switching characteristics and confirmed in the Functional Block Diagram and Device Comparison Table of the official datasheet.
Does TCAN1042VDRBRQ1 require both VCC and VIO to operate?
TCAN1042VDRBRQ1 requires VCC (5 V) for core transceiver operation and VIO (3.0–5.5 V) to set logic thresholds and RXD output levels. In standby mode, VCC may be removed while VIO remains powered to maintain RXD state and enable wake detection - a key feature confirmed in Section 9.4 Device Functional Modes.
What is the bus fault protection rating for TCAN1042VDRBRQ1?
The TCAN1042VDRBRQ1 has ±58 V bus fault protection on CANH and CANL terminals, as specified in Absolute Maximum Ratings (Table 7.1) and Device Comparison Table. This applies to all non-"H" variants; "H" variants (e.g., TCAN1042HDRBRQ1) provide ±70 V protection.
Is TCAN1042VDRBRQ1 pin-compatible with TCAN1042DRBRQ1?
No - TCAN1042VDRBRQ1 and TCAN1042DRBRQ1 are not pin-compatible. Pin 5 is NC on TCAN1042DRBRQ1 but VIO on TCAN1042VDRBRQ1. This difference is explicitly documented in Table 6-1 Pin Functions and Figures 6-1 through 6-4, requiring PCB layout changes for substitution.
What thermal performance can be expected from TCAN1042VDRBRQ1 in VSON-8 (DRB) package?
In the VSON-8 (DRB) package, TCAN1042VDRBRQ1 has RθJA = 48.3°C/W (JEDEC High-K board) and RθJB = 17.2°C/W. Thermal shutdown activates at 170°C with 5°C hysteresis. These values are measured per JESD51 standards and published in Section 7.5 Thermal Information of the datasheet.
