Product details
Overview
SN65HVD230QDRG4Q1 from Texas Instruments is an AEC-Q100 qualified 3.3-V CAN transceiver for automotive and industrial networks. It provides differential transmit/receive capability compliant with ISO 11898, supports signaling rates up to 1 Mbps, features 370 µA typical standby current, ±25 V common-mode transient tolerance, and operates across –40°C to 125°C.
For engineers reviewing the SN65HVD230QDRG4Q1 datasheet, SN65HVD230QDRG4Q1 pinout, SN65HVD230QDRG4Q1 application, or SN65HVD230QDRG4Q1 equivalent, key selection criteria include bus fault protection, slope control via RS pin, Vref output availability, thermal shutdown behavior, and compatibility with TMS320Lx240x DSPs in harsh environments.
Technical Context
The SN65HVD230QDRG4Q1 implements a fully differential physical layer interface between a 3.3-V CAN controller and the CAN bus. Its driver uses open-collector outputs with controlled slew via external RS resistor (10–100 kΩ), while the receiver includes open-circuit fail-safe logic and 100 mV hysteresis for noise immunity.
RS (pin 8) enables three operating modes: high-speed (RS = GND), slope-controlled (RS = resistor-to-GND), and low-current standby (RS > 0.75×VCC). Vref (pin 5) delivers a stable VCC/2 reference for external biasing or diagnostics, and unpowered nodes present high-impedance bus termination to prevent bus disturbance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 3.6 V - Enables direct integration with 3.3-V microcontrollers and DSPs without level-shifting. |
| Signaling Rate | Up to 1 Mbps - Meets ISO 11898 high-speed CAN requirements for real-time automotive ECUs. |
| Standby Current | 370 µA typical - Reduces system power during idle without disabling receiver monitoring. |
| Common-Mode Range | –2 V to +7 V - Supports operation in electrically noisy vehicle chassis environments. |
| Bus Transient Tolerance | ±25 V - Withstands load-dump and inductive switching events without latch-up or damage. |
| ESD Protection | 15-kV HBM on CANH/CANL - Eliminates need for external TVS diodes in many automotive designs. |
| Receiver Thresholds | VIT+ = 750–900 mV, VIT− = 500–650 mV - Provides robust noise margin against EMI-induced false triggering. |
Pinout & Package
SN65HVD230QDRG4Q1 is housed in an 8-pin SOIC (D) package with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC footprint. The package is RoHS-compliant, tape-and-reel ready (suffix R), and rated for automotive temperature range (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D | Driver input | CMOS-compatible logic input accepting 0.8 V / 2.0 V thresholds; connects directly to CAN controller TX. |
| GND | Ground reference | Primary return path for supply and signal currents; must be low-inductance connection to minimize ground bounce. |
| VCC | Supply voltage | 3.3-V power input; requires local 100-nF ceramic decoupling placed within 5 mm of pin. |
| R | Receiver output | CMOS-compatible logic output driving CAN controller RX; active-high dominant indication. |
| Vref | Reference voltage | Stable VCC/2 output (±5% at ±5 µA); used for biasing external comparators or ADC references. |
| CANL | Low bus terminal | Differential bus output/input; connects to twisted-pair CAN_L line; withstands –7 V to +16 V. |
| CANH | High bus terminal | Differential bus output/input; connects to twisted-pair CAN_H line; withstands –7 V to +16 V. |
| RS | Standby/slope control | Configures mode: GND = high-speed, 10–100 kΩ to GND = slope control, >0.75×VCC = standby. |
Key Features
| Feature | Design Value |
|---|---|
| ISO 11898 compliance | Fully meets physical layer requirements for high-speed CAN, enabling interoperability with all standard-compliant nodes. |
| Open-circuit fail-safe receiver | Outputs logic high when CANH/CANL are open or disconnected - prevents undefined controller states during wiring faults. |
| Thermal shutdown protection | Disables driver and places bus pins in high-Z state above safe junction temperature - prevents thermal runaway in overcurrent conditions. |
| Unpowered node isolation | Bus terminals enter high-impedance state when VCC = 0 V - eliminates bus contention during hot-plug or power sequencing. |
| Controlled driver transition times | Slope-adjustable rise/fall times (2–15 V/µs) via RS pin resistor - balances EMI reduction and timing margin for long cables. |
Applications
| Automotive Powertrain ECU | Industrial PLC Backplane |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD231QDRG4Q1 | 0.1 µA sleep mode (vs. 370 µA standby); both driver and receiver disabled in sleep; no Vref output. | Better suited for ultra-low-power wake-on-CAN systems where full receiver monitoring is not required during sleep. | Select SN65HVD231QDRG4Q1 only if deep-sleep current is critical and Vref is unused; not drop-in due to different RS behavior and missing Vref. |
| TCAN1042DRQ1 | Higher 70-V bus fault protection; integrated 3.3-V LDO; split VIO for flexible logic interfacing; no Vref pin. | Preferred for new designs requiring enhanced fault tolerance or single-supply simplification; supports 3.3-V or 5-V controller I/O. | Choose TCAN1042DRQ1 for next-gen designs needing higher fault robustness or simplified power architecture; pinout differs and requires layout update. |
Compared with SN65HVD231QDRG4Q1 and TCAN1042DRQ1, SN65HVD230QDRG4Q1 uniquely retains receiver activity in standby and provides Vref - making it optimal for legacy 3.3-V DSP interfaces requiring continuous bus monitoring and analog reference support without added components.

FAQ
What is the maximum signaling rate supported by the SN65HVD230QDRG4Q1?
The SN65HVD230QDRG4Q1 supports signaling rates up to 1 Mbps, as defined by the ISO 11898 standard for high-speed CAN. This rate is achievable with proper bus termination, controlled slew (via RS pin), and cable lengths under 40 meters. At 1 Mbps, propagation delay (tLOOP) remains ≤135 ns in high-speed mode, ensuring timing margin for most automotive and industrial controllers.
How does the RS pin function in the SN65HVD230QDRG4Q1?
In the SN65HVD230QDRG4Q1, the RS pin (pin 8) controls three operating modes: grounding RS enables high-speed mode with fastest transitions; connecting a 10–100 kΩ resistor to GND enables slope control (≈2–15 V/µs slew); applying >0.75×VCC places the device in standby mode (370 µA ICC, receiver active). Unlike SN65HVD231QDRG4Q1, SN65HVD230QDRG4Q1 keeps the receiver enabled during standby.
Does the SN65HVD230QDRG4Q1 provide a voltage reference output?
Yes, the SN65HVD230QDRG4Q1 provides a Vref output on pin 5, delivering a precise VCC/2 voltage (0.45×VCC to 0.55×VCC at ±5 µA load). This reference is stable across temperature and supply variation, and is commonly used to bias external comparators, ADC references, or diagnostic circuits - a feature absent in SN65HVD231QDRG4Q1 and SN65HVD232QDRG4Q1.
What protection features does the SN65HVD230QDRG4Q1 include?
The SN65HVD230QDRG4Q1 includes ±25 V common-mode transient protection, 15-kV HBM ESD protection on CANH/CANL, thermal shutdown, open-circuit receiver fail-safe, and unpowered node isolation. These features eliminate the need for external TVS diodes in most automotive applications and ensure reliable operation during load dump, ground bounce, and bus disconnection events.
Is the SN65HVD230QDRG4Q1 pin-compatible with other devices in the family?
SN65HVD230QDRG4Q1 is pin-compatible with SN65HVD231QDRG4Q1 and SN65HVD232QDRG4Q1 in the same SOIC-8 (D) package, sharing identical pin numbering and placement. However, functional differences exist: SN65HVD231QDRG4Q1 lacks Vref and enters full sleep (receiver off), while SN65HVD232QDRG4Q1 has no RS or Vref functionality. Board reuse is possible but requires firmware and schematic validation.
