Product details
Overview
SN65HVD233DR from Texas Instruments is a 3.3-V CAN bus transceiver that provides bidirectional differential signaling between a CAN controller and the ISO 11898-2-compliant CAN bus, supporting data rates up to 1 Mbps, featuring ±36 V bus fault protection, ±16 kV HBM ESD rating on bus pins, and loopback diagnostic mode for self-test without bus disturbance.
For engineers reviewing the SN65HVD233DR datasheet, SN65HVD233DR pinout, SN65HVD233DR application, or SN65HVD233DR equivalent, this device is selected for industrial automation nodes requiring robust bus interface, low-power standby (200 µA), adjustable slew rate via RS pin, and compatibility with 5-V tolerant LVTTL I/Os in harsh environments.
Technical Context
The SN65HVD233DR implements a fully integrated CAN physical layer transceiver with driver and receiver circuits sharing a single 3.3-V supply. Its loopback mode (enabled by LBK pin) isolates the bus while maintaining internal D→R signal path for controller diagnostics.
It supports three operational modes via the RS pin: high-speed (RS = GND), slope-controlled (RS pulled to GND via 10–100 kΩ), and standby (RS = VCC). Common-mode range spans –7 V to +12 V, enabling operation across noisy industrial ground offsets and supporting up to 120 nodes on a single bus due to high input impedance (>40 kΩ differential).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - Single 3.3-V rail simplifies power design; no level-shifting required for 3.3-V microcontrollers. |
| Data Rate | Up to 1 Mbps - Supports high-speed CAN applications including SAE J1939 and CANopen real-time control loops. |
| Bus Fault Protection | ±36 V - Withstands sustained overvoltage events such as load dump or wiring misconnection in vehicle or factory settings. |
| ESD Rating (Bus Pins) | ±16 kV HBM - Eliminates need for external TVS diodes in many industrial enclosures per IEC 61000-4-2 Level 4. |
| Standby Current | 200 µA typical - Enables low-power wake-on-CAN functionality in battery-backed or energy-constrained nodes. |
| Common-Mode Range | –7 V to +12 V - Accommodates ground potential differences across long cable runs in building HVAC or motor drive systems. |
| Node Count Support | 120 nodes - High receiver input impedance allows dense network topologies without signal degradation. |
| Loopback Delay | 7.5–12 ns - Enables fast local diagnostics with minimal timing impact on controller firmware execution. |
Pinout & Package
SN65HVD233DR is housed in an SOIC-8 package (4.90 mm × 3.91 mm body size), surface-mount, RoHS-compliant, with standard 1.27-mm pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| D (Pin 1) | Driver Input | LVTTL-compatible transmit data input (TXD); 5-V tolerant, drives internal driver stage. |
| GND (Pin 2) | Ground Reference | Primary return path for VCC and internal bias; must be low-impedance connection to system ground plane. |
| VCC (Pin 3) | Power Supply | 3.3-V supply input; requires local 100-nF ceramic decoupling capacitor placed within 5 mm of pin. |
| R (Pin 4) | Receiver Output | LVTTL-compatible receive data output (RXD); 5-V tolerant, sinks/supplies up to ±10 mA. |
| LBK (Pin 5) | Loopback Control | Active-high logic input; enables internal D→R path while placing CANH/CANL in high-Z to isolate bus during self-test. |
| CANL (Pin 6) | Bus Low Terminal | Differential bus line terminal; connects directly to CAN bus twisted pair; rated for ±36 V fault tolerance. |
| CANH (Pin 7) | Bus High Terminal | Differential bus line terminal; pairs with CANL; supports common-mode transients up to ±100 V. |
| RS (Pin 8) | Mode/Slew Control | Configures operation: GND = high-speed mode, VCC = standby, 10–100 kΩ to GND = adjustable slew rate (2–15 V/µs). |
Key Features
| Feature | Design Value |
|---|---|
| Loopback Diagnostic Mode | Enables controller-initiated bus-free validation of TX/RX signal path integrity with <12 ns latency and no bus contention. |
| Adjustable Driver Slew Rate | Configurable via external RS-to-GND resistor (10–100 kΩ) to optimize EMI emissions vs. timing margin in layout-constrained systems. |
| Unpowered Node Bus Isolation | Remains high-impedance on CANH/CANL when VCC = 0 V, preventing fault current injection into live bus during hot-swap or power sequencing. |
| Thermal Shutdown Protection | Activates at 170°C junction temperature and auto-recovers upon cooling, preventing latch-up or permanent damage during overload. |
| Glitch-Free Power Cycling | Ensures stable R output state during VCC ramp-up/down; avoids spurious CAN frame transmission during boot or brownout. |
| 5-V Tolerant I/Os | D and R pins accept 0–5.5 V logic levels, enabling direct interfacing with legacy 5-V microcontrollers without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CAN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN65HVD230DR | Lower quiescent current (120 µA standby), no loopback mode, identical SOIC-8 package and pinout. | Lacks LBK pin functionality; unsuitable for applications requiring embedded self-test without bus interruption. | Select when lowest possible standby power is critical and loopback diagnostics are handled at controller software level. |
| TCAN1042DR | Higher bus fault tolerance (±70 V), integrated wake-up comparator, same 3.3-V supply and 1-Mbps capability. | Supports partial networking and selective wake-up; not pin-compatible - requires PCB redesign for CANH/CANL and WAKE pin routing. | Choose for automotive or off-road equipment where extreme voltage transients exceed ±36 V and wake-on-CAN is required. |
Compared with SN65HVD230DR and TCAN1042DR, the SN65HVD233DR uniquely balances diagnostic readiness (via LBK), industrial-grade fault resilience, and drop-in SOIC-8 compatibility - making it optimal for programmable logic controllers and field-deployed automation nodes needing verified physical-layer health.

FAQ
What is the function of the LBK pin on the SN65HVD233DR?
The LBK (Loopback) pin on the SN65HVD233DR is an active-high input that enables internal driver-to-receiver signal path while placing CANH and CANL terminals in high-impedance state. This allows the host controller to verify TX/RX functionality without transmitting onto the live CAN bus - a key capability for pre-deployment diagnostics and runtime health checks in the SN65HVD233DR.
Does the SN65HVD233DR support 5-V logic interfaces?
Yes, the SN65HVD233DR features 5-V tolerant D (TXD) and R (RXD) pins, accepting input voltages from 0 V to 5.5 V while operating from a 3.3-V supply. This eliminates external level shifters when interfacing with legacy 5-V microcontrollers or FPGAs, preserving signal integrity and reducing BOM cost in mixed-voltage systems using the SN65HVD233DR.
How does the RS pin affect slew rate and EMI in the SN65HVD233DR?
The RS pin on the SN65HVD233DR controls driver output transition speed: grounded for maximum speed (~20 ns rise/fall), pulled to GND via 10 kΩ for ~15 V/µs slew, or 100 kΩ for ~2 V/µs. Slower slew reduces high-frequency spectral content, easing compliance with CISPR 25/EN 55022 emissions limits - a critical design lever in compact or unshielded enclosures using the SN65HVD233DR.
What is the maximum number of nodes supported on a CAN bus using the SN65HVD233DR?
The SN65HVD233DR supports up to 120 nodes on a single CAN bus due to its high differential input resistance (>40 kΩ) and low bus loading. This scalability is achieved without repeaters and remains valid under recommended termination (120 Ω at each end) and cable length constraints (<40 m at 1 Mbps), making the SN65HVD233DR ideal for large-scale industrial networks.
Is thermal shutdown protection implemented in the SN65HVD233DR?
Yes, the SN65HVD233DR includes integrated thermal shutdown protection that activates at approximately 170°C junction temperature. When triggered, the driver and receiver are disabled until the die cools below the hysteresis threshold (~155°C), preventing permanent damage during sustained overload, short-circuit faults, or inadequate heatsinking - a safeguard confirmed in the SN65HVD233DR datasheet Section 8.4.
