Product details
Overview
TCAN337GDR from Texas Instruments is a 3.3V CAN FD transceiver in SOIC-8 package, supporting up to 5 Mbps data rate and compliant with ISO 11898-2. It features fault output (FAULT pin), silent mode, ±12 V common-mode range, ±14 V bus fault protection, and total loop delay < 135 ns. Used in industrial automation and telecom base station control where robust CAN FD communication and fault reporting are required.
For engineers reviewing the TCAN337GDR datasheet, TCAN337GDR pinout, TCAN337GDR application, or TCAN337GDR equivalent, this page delivers verified specifications, SOIC-8 terminal mapping, silent-mode operation details, fault-output behavior, and direct alternatives for CAN FD network design with integrated diagnostics.
Technical Context
The TCAN337GDR implements a high-speed CAN physical layer interface with driver/receiver pair optimized for Flexible Data Rate (FD) timing symmetry-tBUS_SYM_5 ≤ 210 ns and tREC_SYM_5 ≤ 220 ns at 5 Mbps. Its integrated FAULT open-drain output signals bus or internal faults including TXD/RXD dominant time-out events and undervoltage conditions.
It operates across –40°C to 125°C ambient, supports silent mode (pin 8 = S), and includes driver/receiver DTO, thermal shutdown (175°C), and IEC 61000-4-2 ±12 kV contact ESD protection on CANH/CANL-enabling system-level robustness without external protection components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 5 Mbps - enables CAN FD high-speed data phase in automotive and industrial networks. |
| Supply Voltage | 3.3 V nominal (3.0–3.6 V) - directly interfaces with 3.3 V CAN controllers without level-shifting. |
| Common-Mode Range | ±12 V - ensures reliable operation in electrically noisy environments like motor drives and factory floors. |
| Bus Fault Protection | ±14 V on CANH/CANL - prevents damage during load-dump or ground-shift transients. |
| Total Loop Delay | < 135 ns - meets strict CAN FD timing budgets for deterministic low-latency communication. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood, industrial, and telecom infrastructure applications. |
| ESD Protection | IEC 61000-4-2 ±12 kV contact on CANH/CANL - eliminates need for external TVS diodes in most designs. |
Pinout & Package
TCAN337GDR is housed in an 8-pin SOIC package (4.9 mm × 6 mm), compatible with standard PCB footprints and reflow processes. Pin functions are device-specific per TI's Device Options table; TCAN337G variants assign Pin 5 to FAULT (open-drain output) and Pin 8 to S (silent mode enable).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Input | CMOS-level transmit data input; LOW = dominant, HIGH = recessive; internal pull-up. |
| 2 - GND | Ground | Primary reference for all logic and analog circuitry; must be low-impedance connection. |
| 3 - VCC | Supply | 3.3 V power input; includes undervoltage lockout (UVLO) with 200 mV hysteresis. |
| 4 - RXD | Output | CMOS-level receive data output; tri-state capable; LOW = dominant, HIGH = recessive. |
| 5 - FAULT | Output | Open-drain fault indicator - asserts LOW on TXD/RXD DTO, thermal shutdown, or UV event. |
| 6 - CANL | I/O | Low-side CAN bus line; internally biased; withstands ±14 V fault voltage. |
| 7 - CANH | I/O | High-side CAN bus line; internally biased; withstands ±14 V fault voltage. |
| 8 - S | Input | Silent mode enable - HIGH disables driver output while receiver remains active; used for bus monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Fault Output Pin | Open-drain FAULT pin reports TXD/RXD dominant time-out, undervoltage, and thermal shutdown - enables real-time diagnostics without software polling. |
| Silent Mode | Pin 8 (S) enables bus monitoring without affecting bus state - critical for non-intrusive debugging and node isolation in live CAN FD networks. |
| 5 Mbps CAN FD Timing | tBUS_SYM_5 ≤ 210 ns and tREC_SYM_5 ≤ 220 ns - ensures bit-width symmetry required for reliable high-speed FD arbitration and data phases. |
| Integrated Protection | Driver/receiver DTO, ±12 kV IEC ESD, ±14 V bus fault tolerance, and thermal shutdown - reduces BOM count and improves field reliability. |
| Unpowered Bus Isolation | High-impedance CANH/CANL and logic pins when VCC = 0 V - prevents loading of live bus during hot-swap or power sequencing. |

FAQ
What is the maximum data rate supported by TCAN337GDR?
The TCAN337GDR supports up to 5 Mbps, meeting CAN FD high-speed data phase requirements. This is confirmed in TI's datasheet Section 5.6 (Switching Characteristics), where tBUS_SYM_5 and tREC_SYM_5 are specified for 5 Mbps operation. The "G" suffix explicitly denotes the 5 Mbps variant within the TCAN33x family.
Does TCAN337GDR include a fault reporting pin, and how does it function?
Yes, TCAN337GDR includes an open-drain FAULT pin (Pin 5) that asserts LOW during TXD dominant time-out, RXD dominant time-out, undervoltage lockout, or thermal shutdown. As documented in Figures 5-1 and 5-2 and Section 5.5, this pin enables hardware-level fault detection without MCU intervention - a key differentiator versus TCAN330/332/334 variants.
What package type is TCAN337GDR supplied in, and what are its dimensions?
TCAN337GDR is supplied in an 8-pin SOIC package measuring 4.9 mm × 6 mm (nominal, including pins). This is explicitly stated in the "Package Information" table and Section 9 of the TI datasheet. The SOIC-8 footprint ensures drop-in compatibility with existing CAN transceiver layouts.
How does silent mode operate on TCAN337GDR, and which pin controls it?
Silent mode on TCAN337GDR is enabled by driving Pin 8 (S) HIGH, which disables the driver output while keeping the receiver active. This allows non-intrusive bus monitoring - essential for debugging and diagnostics. The functionality is defined in Table 4-1 and Section 4 ("Pin Configuration and Functions") of the official datasheet.
Is TCAN337GDR compatible with 5 V CAN controllers or only 3.3 V systems?
TCAN337GDR is a 3.3 V-only transceiver (VCC = 3.0–3.6 V), but it is fully interoperable with 5 V CAN controllers on the same bus because its bus side (CANH/CANL) is voltage-level agnostic and compliant with ISO 11898-2. Logic-side I/O is strictly 3.3 V tolerant - direct connection to 5 V MCU pins requires level translation.
