Product details
Overview
TCAN332GDR 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 operates across –40°C to 125°C, features ±12 V common-mode range, ±14 V bus fault protection, and total loop delay <135 ns. It enables robust high-speed CAN communication in automotive and industrial control networks.
For engineers reviewing the TCAN332GDR datasheet, TCAN332GDR pinout, TCAN332GDR application, or TCAN332GDR equivalent, key selection criteria include CAN FD timing symmetry (ΔtSYM_5 ≤ 15 ns), driver/receiver dominant time-out (1.2–3.8 ms / 1.6–5 ms), IEC 61000-4-2 ±12 kV contact ESD rating, and SOIC-8 drop-in compatibility with legacy 3.3V CAN systems.
Technical Context
The TCAN332GDR implements a fully differential CAN physical layer interface with matched dominant/recessive common-mode behavior for superior EMC performance. Its integrated TXD and RXD dominant time-out (DTO) circuits autonomously release the bus or RXD output after configurable timeout periods, preventing network lock-up due to local faults.
Unlike TCAN334G/TCAN337G variants, TCAN332GDR lacks standby (STB) and fault (FAULT) pins - Pin 5 and Pin 8 are NC (no connect). It supports only Normal mode operation and requires no external biasing, with bus pins remaining high-impedance when unpowered and glitch-free power sequencing.
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 | 3.3 V nominal (3.0–3.6 V) - directly interfaces with 3.3V CAN controllers without level-shifting. |
| Common-Mode Range | ±12 V - ensures reliable operation in noisy industrial environments with ground offsets. |
| Bus Fault Protection | ±14 V - protects against transients and short-circuits on CANH/CANL without external TVS diodes. |
| Total Loop Delay | <135 ns - meets strict CAN FD timing budgets for 5 Mbps bit timing and sampling window integrity. |
| ESD Rating | IEC 61000-4-2 ±12 kV contact - eliminates need for system-level ESD protection components. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and factory-floor industrial deployment. |
Pinout & Package
TCAN332GDR is housed in an industry-standard 8-pin SOIC package (4.9 mm × 6.0 mm), enabling drop-in replacement for legacy CAN transceivers. Pin functions are fixed per device variant: Pins 5 and 8 are NC (no connect), eliminating mode configuration overhead.
| 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 VCC and signal return; must be low-impedance connection to system ground plane. |
| 3 - VCC | Supply | 3.3 V power input; bypass capacitor (100 nF) required within 1 cm of pin for noise suppression. |
| 4 - RXD | Output | CMOS-level receive data output; tri-state capable; drives HIGH for recessive, LOW for dominant. |
| 5 - NC | No Connect | Not internally bonded; must be left floating - no routing or termination required. |
| 6 - CANL | I/O | Low-side CAN bus line; differential pair with CANH; withstands ±14 V fault conditions. |
| 7 - CANH | I/O | High-side CAN bus line; differential pair with CANL; matched impedance for EMI reduction. |
| 8 - NC | No Connect | Not internally bonded; must be left floating - no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| 5 Mbps CAN FD support | Validated timing symmetry (ΔtSYM_5 ≤ 15 ns) ensures accurate bit sampling at 5 Mbps, critical for payload-rich CAN FD frames. |
| Integrated TXD/RXD DTO | Driver DTO (1.2–3.8 ms) and receiver DTO (1.6–5 ms) autonomously recover bus/RXD from stuck-dominant faults without MCU intervention. |
| Unpowered bus isolation | Bus pins (CANH/CANL) and logic pins enter high-impedance state when VCC = 0 V - prevents loading of live CAN bus during power cycling. |
| Glitch-free power sequencing | No false dominant pulses occur during VCC ramp-up/down - avoids spurious bus arbitration errors during startup or brownout. |
| ±12 kV IEC ESD protection | Eliminates need for external ESD diodes on CANH/CANL, reducing BOM count and PCB area in space-constrained designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCAN334GDR | Includes STB pin for low-power standby mode with wake detection; same 5 Mbps capability and SOIC-8 package. | Required where battery-powered nodes need ultra-low quiescent current (<20 µA) during sleep. | Select TCAN334GDR only if standby mode functionality is needed; TCAN332GDR offers simpler control with no mode pins. |
| SN65HVD233DGKR | 1 Mbps max data rate; no CAN FD timing symmetry specs; lower ESD rating (±8 kV IEC); same SOIC-8 footprint. | Suitable for cost-sensitive 1 Mbps CAN networks without FD requirements or stringent ESD demands. | Choose SN65HVD233DGKR only for legacy 1 Mbps systems; TCAN332GDR provides FD readiness and higher robustness. |
Compared with TCAN334GDR, TCAN332GDR simplifies design by removing standby control complexity while retaining full 5 Mbps CAN FD performance and protection. Against SN65HVD233DGKR, TCAN332GDR delivers 5× higher data throughput, tighter timing symmetry, and 50% higher IEC ESD immunity - justifying upgrade in next-gen CAN FD deployments.

FAQ
What is the maximum data rate supported by TCAN332GDR?
TCAN332GDR supports up to 5 Mbps, validated for CAN FD operation with specified timing symmetry (ΔtSYM_5 ≤ 15 ns) and loop delay (<135 ns). This enables high-bandwidth payload transmission while maintaining ISO 11898-2 compliance. The 5 Mbps capability is intrinsic to the "G" suffix variant and confirmed in TI's SLLSEQ7F datasheet Section 5.6.
Does TCAN332GDR support standby or shutdown modes?
No, TCAN332GDR supports only Normal mode operation. Pins 5 (SHDN/FAULT) and 8 (S/STB) are NC (no connect), confirming absence of standby, silent, or shutdown functionality. This distinguishes it from TCAN334GDR (standby) and TCAN337GDR (fault output). All operational current specs in the datasheet apply exclusively to Normal mode.
What package type is used for TCAN332GDR?
TCAN332GDR uses an 8-pin SOIC package (package code D), measuring 4.9 mm × 6.0 mm. This footprint ensures drop-in compatibility with legacy CAN transceivers and supports standard automated assembly processes. The datasheet explicitly lists "SOIC (8)" for TCAN332G in the Package Information table.
How does TCAN332GDR handle bus faults and ESD events?
TCAN332GDR provides ±14 V bus fault protection on CANH/CANL and ±12 kV IEC 61000-4-2 contact discharge ESD rating. These protections are integrated into the silicon - no external components required. The device also features driver and receiver dominant time-out (DTO) to autonomously recover from stuck-dominant faults, enhancing network robustness beyond passive protection.
Is TCAN332GDR compatible with 5V CAN controllers?
TCAN332GDR is a 3.3V-only transceiver and is not directly compatible with 5V CAN controllers. However, it is fully interoperable with 5V CAN transceivers on the same bus because its differential bus voltage levels (e.g., VOD(D) = 1.6–3 V) meet ISO 11898-2 thresholds regardless of node supply voltage. Level-shifting is required only for the logic-side TXD/RXD signals.
