Product details
Overview
TCAN332GDCNR 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 ±12 V common-mode range, bus fault protection to ±14 V, and total loop delay < 135 ns. It operates across –40°C to 125°C and enables robust communication in automotive and industrial CAN FD networks.
For engineers reviewing the TCAN332GDCNR datasheet, TCAN332GDCNR pinout, TCAN332GDCNR application, or TCAN332GDCNR equivalent, this page delivers verified electrical specs, mode behavior, thermal performance, ESD resilience (±12 kV IEC 61000-4-2 contact), and design-critical timing symmetry for CAN FD bit-rate validation at 2 Mbps and 5 Mbps.
Technical Context
The TCAN332GDCNR implements a high-speed CAN physical layer transceiver with integrated dominant/recessive time-out (DTO) logic, undervoltage protection on VCC, and thermal shutdown. Its driver and receiver paths are optimized for low skew and matched common-mode behavior to ensure EMC robustness and precise bit timing alignment required for CAN FD operation.
Unlike TCAN334G/TCAN337G variants, TCAN332GDCNR supports only Normal mode - no standby, silent, or fault output functionality - and uses NC pins at positions 5 and 8. Its SOT-23 package enables space-constrained PCB layouts while maintaining full compatibility with 3.3V CAN controllers and coexistence with 5V transceivers on the same bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 5 Mbps - enables CAN FD flexible data-rate operation in high-throughput vehicle ECUs and industrial gateways. |
| Supply Voltage | 3.0–3.6 V - single 3.3V rail directly interfaces with modern 3.3V microcontrollers without level-shifting. |
| Total Loop Delay | 100–135 ns - ensures tight timing margins for 5 Mbps bit widths (200 ns nominal), critical for CAN FD arbitration and data phase integrity. |
| Common-Mode Range | ±12 V - maintains reliable operation under severe ground offset conditions in heavy machinery and automotive chassis networks. |
| Bus Fault Protection | ±14 V - prevents latch-up or damage during load-dump transients or wiring faults in harsh environments. |
| ESD Protection | ±12 kV IEC 61000-4-2 contact discharge - eliminates need for external TVS diodes in system-level ESD compliance designs. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control cabinet deployment. |
Pinout & Package
TCAN332GDCNR is housed in an 8-pin SOT-23 package (2.9 mm × 1.6 mm), optimized for compact PCB footprints and automated assembly. Pin functions are validated per TI SLLSEQ7F Rev. May 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - TXD | Input | CMOS-level transmit data input; LOW = dominant, HIGH = recessive; internal pull-up ensures defined state when un-driven. |
| 2 - GND | Ground | Primary reference for all analog and digital circuitry; must be low-impedance connection to minimize noise coupling. |
| 3 - VCC | Power Supply | 3.3V supply input; requires local 100 nF ceramic decoupling capacitor placed ≤2 mm from pin. |
| 4 - RXD | Output | CMOS-level receive data output; tri-state capable; drives HIGH for recessive, LOW for dominant bus states. |
| 5 - NC | No Connect | Not internally bonded; must remain unconnected on PCB to avoid parasitic coupling or unintended biasing. |
| 6 - CANL | I/O | Low-side CAN bus terminal; differential pair with CANH; withstands ±14 V fault voltage relative to GND. |
| 7 - CANH | I/O | High-side CAN bus terminal; differential pair with CANL; matched impedance and timing to CANL for signal integrity. |
| 8 - NC | No Connect | Not internally bonded; floating per device configuration table; no routing or solder mask opening required. |
Key Features
| Feature | Design Value |
|---|---|
| 5 Mbps CAN FD support | Validated timing symmetry (ΔtSYM_5 ≤ 15 ns) and loop delay enable error-free data phase transmission at 5 Mbps, meeting ISO 11898-1 FD requirements. |
| Integrated TXD/RXD DTO | Driver dominant time-out (1.2–3.8 ms) and receiver dominant time-out (1.6–5 ms) prevent bus lockup from firmware errors or hardware faults. |
| Unpowered bus isolation | High-impedance CANH/CANL and logic pins when VCC = 0 V eliminate loading on live buses during hot-swap or power sequencing. |
| Glitch-free power cycling | No false dominant pulses on TXD or spurious transitions on RXD during VCC ramp-up/down, ensuring protocol controller stability. |
| Thermal shutdown + UVLO | 175°C thermal cutoff with 5°C hysteresis and 2.2–2.6 V rising-edge UV detection protect against overtemperature and brownout-induced malfunction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN332DR | SOIC-8 package (4.9 mm × 6 mm); identical electrical specs and pinout mapping except for larger footprint and higher RθJA (114.4°C/W vs 154.4°C/W). | Suitable for prototyping or legacy SOIC-based designs where board rework is impractical; not drop-in compatible due to package size mismatch. | Select TCAN332DR only when SOT-23 placement is mechanically infeasible or thermal margin allows higher junction rise. |
| SN65HVD233DGKR | 1 Mbps max rate; no CAN FD support; lacks DTO, thermal shutdown, and IEC 61000-4-2 ESD rating; VCC range 3–3.6 V same. | Limited to classical CAN networks; unsuitable for FD data-phase throughput or automotive OEM Tier-1 compliance requiring >2 Mbps. | Choose SN65HVD233DGKR only for cost-sensitive, non-FD, non-automotive applications where 1 Mbps suffices and system-level ESD protection is already implemented externally. |
Compared with TCAN332GDCNR, TCAN332DR offers identical functionality in a larger SOIC package ideal for manual assembly or thermal-limited environments, while SN65HVD233DGKR provides basic CAN-2.0B capability at lower cost but omits FD timing, fault resilience, and certified ESD robustness required for next-gen designs.

FAQ
What is the maximum data rate supported by TCAN332GDCNR?
The TCAN332GDCNR supports data rates up to 5 Mbps, validated for CAN FD operation with specified timing symmetry (ΔtSYM_5 ≤ 15 ns) and loop delay (100–135 ns). This enables high-throughput data-phase transmission while maintaining compatibility with ISO 11898-1 FD timing requirements. TCAN332GDCNR achieves this without external components, unlike legacy 1 Mbps transceivers.
Does TCAN332GDCNR support standby or silent mode?
No, TCAN332GDCNR supports only Normal mode operation. Unlike TCAN334G or TCAN337G variants, it does not include standby (STB), silent (S), or fault (FAULT) functionality. Pins 5 and 8 are designated NC (No Connect) per TI's device comparison table, confirming absence of mode-control features. TCAN332GDCNR is optimized for always-on, high-speed CAN FD nodes.
What package type is used for TCAN332GDCNR?
TCAN332GDCNR uses an 8-pin SOT-23 package measuring 2.9 mm × 1.6 mm, as confirmed in TI's mechanical information section. This compact footprint supports high-density PCB layouts and automated surface-mount assembly. The pinout matches the SOIC-8 variant electrically but is not mechanically interchangeable due to dimensional and thermal differences.
How does TCAN332GDCNR handle undervoltage conditions?
TCAN332GDCNR incorporates undervoltage lockout (UVLO) with rising-edge detection at 2.2–2.6 V and falling-edge at 1.65–2.5 V, plus 200 mV hysteresis. When VCC drops below threshold, the device enters protected mode - disabling driver/receiver functionality and placing TXD/RXD in high-impedance state. This prevents metastable outputs and bus contention during brownout events, ensuring safe recovery upon voltage restoration.
Is TCAN332GDCNR compatible with 5V CAN controllers?
TCAN332GDCNR is not directly compatible with 5V CAN controllers at the logic level, as its TXD and RXD pins operate at 3.3V CMOS levels. However, it is fully bus-compatible with 5V CAN transceivers on the same physical CAN bus - meaning TCAN332GDCNR can coexist on shared CANH/CANL lines with 5V transceivers without signal degradation or termination conflicts, provided the host MCU uses 3.3V I/O.
