Product details
Overview
SN65HVD232QDRQ1 from Texas Instruments is an automotive-qualified 3.3-V CAN transceiver designed for ISO 11898-compliant differential bus communication at up to 1 Mbps. It features no standby/sleep mode, no slope control, and no Vref pin-pins 5 and 8 are NC. It interfaces 3.3-V CAN controllers (e.g., TMS320Lx240x DSPs) with industrial and automotive CAN buses, providing robust ±25-V common-mode transient tolerance and 15-kV HBM ESD protection on CANH/CANL.
For engineers reviewing the SN65HVD232QDRQ1 datasheet, SN65HVD232QDRQ1 pinout, SN65HVD232QDRQ1 application, or SN65HVD232QDRQ1 equivalent, this page delivers verified electrical specs, exact terminal roles, automotive-grade thermal shutdown behavior, failsafe open-circuit receiver response, and validated alternative transceivers for CAN node design in harsh environments.
Technical Context
The SN65HVD232QDRQ1 implements a fixed-function CAN physical layer interface with no RS pin control or Vref output-unlike SN65HVD230Q/231Q variants. Its driver and receiver operate continuously when powered, with propagation delays of 35–120 ns (tPLH/tPHL), pulse skew ≤35 ns, and differential rise/fall times of 25–100 ns / 40–80 ns respectively.
It supports a −2 V to +7 V common-mode bus voltage range and withstands ±25 V transients per ISO 11898. Receiver thresholds are VIT+ = 750–900 mV and VIT− = 500–650 mV with 100 mV hysteresis, ensuring reliable dominant/recessive detection under noise and bus fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0 V to 3.6 V - operates strictly within 3.3-V system rails; not 5-V tolerant |
| Signaling Rate | Up to 1 Mbps - meets ISO 11898 high-speed CAN timing requirements |
| Differential Output Voltage (Dominant) | 1.2 V to 3.0 V - ensures sufficient bus differential swing for reliable receiver detection |
| Common-Mode Range | −2 V to +7 V - enables operation across wide ground offsets in vehicle chassis networks |
| ESD Protection (HBM) | 15 kV on CANH/CANL - exceeds automotive EMC immunity requirements per AEC-Q100 |
| Thermal Shutdown | Active protection - forces CANH/CANL into high-impedance state above safe junction temperature |
| Receiver Failsafe | Open-circuit logic-high output - prevents undefined R-pin state if bus wires disconnect |
Pinout & Package
SN65HVD232QDRQ1 uses an 8-pin SOIC (D) package with 1.27-mm pitch, RoHS-compliant, tape-and-reel (suffix R). Pins 5 and 8 are NC (no internal connection); all other pins match the standard CAN transceiver layout.
| 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-impedance in automotive PCB layout |
| VCC | 3.3-V supply input | Powers internal circuitry; requires local 100-nF ceramic decoupling adjacent to pin |
| R | Receiver output | CMOS-compatible logic output driving CAN controller RX; sinks 8 mA / sources 8 mA |
| CANL | Low-side bus line | Differential bus terminal; connects to twisted-pair CAN-L; rated for −7 V to +16 V absolute max |
| CANH | High-side bus line | Differential bus terminal; connects to twisted-pair CAN-H; same voltage rating as CANL |
| NC (Pin 5) | No connection | Not bonded internally; must remain unconnected on PCB; no pull-up/down required |
| NC (Pin 8) | No connection | RS functionality omitted; pin must float or be left unconnected per TI design guidance |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (−40°C to +125°C ambient) - validated for engine bay and body control modules |
| Bus fault protection | Withstands −25 V to +25 V common-mode transients - eliminates need for external TVS on bus lines |
| Unpowered node isolation | CANH/CANL enter high-Z state at VCC < 2.0 V - prevents bus contention during hot-plug or power sequencing |
| Thermal shutdown | Automatic bus disconnection above safe junction temperature - protects against latch-up in overcurrent faults |
| Open-circuit failsafe | R outputs logic high when CANH/CANL are open - ensures controller receives defined idle state |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD230QDRQ1 | Includes RS pin for standby mode (370 µA) and Vref output; slope control enabled via external resistor | Suitable where low-power wake-on-bus or reference voltage sharing is required | Select when system-level power budget allows standby entry and Vref is needed for biasing or ADC reference |
| SN65HVD231QDRQ1 | Includes RS pin for ultra-low sleep mode (0.1 µA); Vref output present; slope control supported | Required for battery-powered nodes needing microamp-level quiescent current during idle | Choose only if deep-sleep capability and Vref are mandatory; incompatible with SN65HVD232QDRQ1 pinout in sleep-control circuits |
Compared with SN65HVD230QDRQ1 and SN65HVD231QDRQ1, SN65HVD232QDRQ1 offers simplified layout (no RS/Vref routing), guaranteed timing consistency (no slope-dependent delays), and lower BOM cost-making it optimal for cost-sensitive, always-on CAN nodes where power gating is unnecessary.

FAQ
What is the operating temperature range for SN65HVD232QDRQ1?
The SN65HVD232QDRQ1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from −40°C to +125°C ambient temperature. This range covers under-hood and cabin-mounted automotive applications, and its thermal shutdown circuit activates before junction temperature exceeds safe limits-ensuring reliability without external thermal monitoring.
Does SN65HVD232QDRQ1 support slope control or standby mode?
No. SN65HVD232QDRQ1 has no slope control or standby/sleep functionality. Pins 5 (Vref) and 8 (RS) are NC-internally unconnected. Unlike SN65HVD230QDRQ1 or SN65HVD231QDRQ1, SN65HVD232QDRQ1 operates continuously when powered, delivering consistent timing and eliminating configuration dependencies.
What happens to SN65HVD232QDRQ1 outputs during power loss?
When VCC drops below ~2.0 V, SN65HVD232QDRQ1 places CANH and CANL into high-impedance states, preventing bus disturbance from unpowered nodes-a critical feature for hot-plug and power-sequencing safety. The R output remains valid until VCC falls below functional threshold, then transitions to high-impedance or indeterminate state per datasheet behavior.
Is SN65HVD232QDRQ1 pin-compatible with SN65HVD230QDRQ1 or SN65HVD231QDRQ1?
Yes-SN65HVD232QDRQ1 shares the identical 8-pin SOIC (D) package and pin mapping (D, GND, VCC, R, CANL, CANH, NC, NC) with SN65HVD230QDRQ1 and SN65HVD231QDRQ1. However, functional differences exist: pins 5 and 8 are unused in SN65HVD232QDRQ1, so boards designed for the '230 or '231 must leave those pins floating to avoid conflict.
What level of ESD protection does SN65HVD232QDRQ1 provide on the CAN bus pins?
SN65HVD232QDRQ1 provides 15-kV HBM ESD protection on CANH and CANL pins-verified per JEDEC JESD22-A114. This exceeds typical automotive requirements and eliminates the need for external ESD diodes in most implementations, reducing BOM count and PCB area while maintaining robustness against assembly and field-handling events.
