Product details
Overview
TCAN337GDCNR from Texas Instruments is a 3.3V CAN FD transceiver in an 8-pin SOT-23 package, supporting data rates up to 5 Mbps, compliant with ISO 11898-2, and featuring fault output (FAULT pin), silent mode, and ±12 V common-mode range. It enables robust high-speed CAN communication in automotive and industrial control networks where bus fault detection and low-power operation are critical.
For engineers reviewing the TCAN337GDCNR datasheet, TCAN337GDCNR pinout, TCAN337GDCNR application, or TCAN337GDCNR equivalent, key selection considerations include its integrated FAULT pin for bus fault reporting, 5 Mbps CAN FD timing symmetry (ΔtSYM_5 ≤ 15 ns), silent mode capability, and IEC 61000-4-2 ±12 kV contact ESD protection on CANH/CANL terminals.
Technical Context
The TCAN337GDCNR implements a differential CAN physical layer interface with matched dominant/recessive common-mode behavior for superior EMC performance. Its driver and receiver paths support CAN FD flexible data-rate operation up to 5 Mbps, with verified loop delay symmetry (tBUS_SYM_5 = 155–210 ns, tREC_SYM_5 = 120–220 ns) and total loop delay < 135 ns under standard load conditions.
It integrates dual dominant time-out (TXD DTO: 1.2–3.8 ms; RXD DTO: 1.6–5 ms), undervoltage lockout (UVLO: 2.2–2.6 V rising, 1.65–2.5 V falling), thermal shutdown (175 °C), and open-drain FAULT output-functions confirmed exclusively for TCAN337/TCAN337G variants per device comparison table and block diagram.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 5 Mbps - supports CAN FD high-speed payload transmission without protocol layer changes. |
| Total Loop Delay | <135 ns - ensures timing margin for 5 Mbps bit timing compliance in standard CAN FD networks. |
| Common-Mode Range | ±12 V - maintains reliable operation across noisy industrial bus environments with ground offsets. |
| ESD Protection | IEC 61000-4-2 ±12 kV contact on CANH/CANL - eliminates need for external TVS diodes in system-level ESD design. |
| Supply Voltage | 3.0–3.6 V - single 3.3 V rail directly interfaces with 3.3 V CAN controllers and MCUs. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial embedded applications. |
| FAULT Pin Output | Open-drain, low-active - signals bus faults (e.g., short-to-battery, short-to-ground) to host controller for diagnostics. |
Pinout & Package
TCAN337GDCNR uses an 8-pin SOT-23 package (2.9 mm × 1.6 mm), optimized for space-constrained PCB layouts while maintaining drop-in compatibility with SOIC-8 footprints via adapter designs. Pin functions are validated per TI SLLSEQ7F Rev. May 2025, Figure 4-4 and Table 4-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Input | CAN controller transmit data input; LOW = dominant, HIGH = recessive; internal pull-up. |
| 2 - GND | Ground | Reference return path for supply and signal integrity; must be low-impedance connection. |
| 3 - VCC | Supply | 3.3 V power input; UVLO circuit monitors this rail to disable outputs during brownout. |
| 4 - RXD | Output | CAN bus receive data output; tri-state capable; drives HIGH/LOW per bus state. |
| 5 - FAULT | Output | Open-drain fault indicator; pulled LOW during TXD/RXD DTO, bus overvoltage, or thermal shutdown. |
| 6 - CANL | I/O | Low-side CAN bus line; differential pair with CANH; ±14 V fault tolerant. |
| 7 - CANH | I/O | High-side CAN bus line; differential pair with CANL; ±14 V fault tolerant. |
| 8 - S | Input | Silent mode enable; HIGH activates silent mode (driver disabled, receiver active); internal pull-down. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated FAULT output | Provides real-time hardware-level bus fault indication (e.g., shorts, overvoltage) without software polling. |
| Silent mode operation | Disables driver while keeping receiver active - enables node monitoring without bus arbitration impact. |
| Dual dominant time-out (DTO) | TXD DTO (1.2–3.8 ms) and RXD DTO (1.6–5 ms) prevent bus lockup from stuck-dominant faults. |
| 5 Mbps CAN FD timing symmetry | ΔtSYM_5 ≤ 15 ns ensures accurate bit sampling at high data rates, meeting ISO 11898-2 FD timing requirements. |
| ±12 kV IEC 61000-4-2 ESD | Eliminates need for external ESD protection components on CANH/CANL, reducing BOM count and layout area. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Backplane Communication |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN FD transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN337DR | SOIC-8 package (4.9 mm × 6 mm); identical electrical specs and pinout except larger footprint. | Preferred where manual assembly, thermal mass, or legacy SOIC-8 layout reuse is required. | Select TCAN337DR when board space permits and SOIC-8 reflow compatibility is prioritized over miniaturization. |
| SN65HVD233DGKR | 1 Mbps max rate; no FAULT pin; no silent mode; only basic TXD/RXD/EN pins; lower ESD (±8 kV IEC). | Limited to legacy CAN networks; unsuitable for CAN FD or fault-diagnostic architectures. | Choose SN65HVD233DGKR only for cost-sensitive, non-FD, non-diagnostic applications where 1 Mbps suffices. |
Compared with TCAN337DR, TCAN337GDCNR offers identical functionality in a 60% smaller SOT-23 package but requires tighter layout control; compared with SN65HVD233DGKR, it delivers 5× higher data rate, integrated fault reporting, and 50% higher system-level ESD immunity-critical for next-generation CAN FD deployments.

FAQ
What is the maximum data rate supported by the TCAN337GDCNR?
The TCAN337GDCNR supports data rates up to 5 Mbps, as confirmed in the Features section and Switching Characteristics table (tBUS_SYM_5 and tREC_SYM_5 parameters) of the official TI datasheet SLLSEQ7F. This enables full CAN FD flexible data-rate operation, unlike 1 Mbps-only variants such as TCAN337. The 5 Mbps capability is intrinsic to the "G" suffix in TCAN337GDCNR and applies specifically to this part number.
Does the TCAN337GDCNR have a dedicated fault reporting pin?
Yes, the TCAN337GDCNR includes a dedicated open-drain FAULT pin (Pin 5), explicitly documented in the Device Options table and Pin Functions table of the TI datasheet. This pin asserts LOW during TXD/RXD dominant time-out events, bus overvoltage (>±14 V), or thermal shutdown-functionality unique to TCAN337 and TCAN337G variants and not present in TCAN330, TCAN332, or TCAN334 families.
What package type and dimensions does the TCAN337GDCNR use?
The TCAN337GDCNR uses an 8-pin SOT-23 package measuring 2.9 mm × 1.6 mm, as specified in the Package Information table and mechanical drawings (Figure 4-4) of TI's SLLSEQ7F datasheet. This compact footprint is distinct from the SOIC-8 option (TCAN337DR) and enables high-density PCB layouts in space-constrained applications like telematics modules and sensor nodes.
How does silent mode operate on the TCAN337GDCNR?
Silent mode on the TCAN337GDCNR is activated by driving Pin 8 (S) HIGH, which disables the driver while keeping the receiver fully functional-confirmed in the Device Options table and Functional Block Diagram. This allows the node to monitor bus traffic without transmitting, preventing interference during diagnostics or partial network shutdowns, and is a feature exclusive to TCAN337/TCAN337G devices.
What level of ESD protection does the TCAN337GDCNR provide on its CAN bus pins?
The TCAN337GDCNR provides IEC 61000-4-2 ±12 kV contact discharge ESD protection on CANH and CANL pins, as stated in the Features list and Electrical Characteristics section (5.2 ESD Ratings) of the TI datasheet. This exceeds typical industry requirements and eliminates the need for external ESD protection components in most system-level designs.
