SN65HVD10D CAN Transceiver

Updated: 2026-08-10

Overview

The SN65HVD10D is a Controller Area Network (CAN) transceiver manufactured by Texas Instruments, designed to facilitate high-speed communication in industrial and automotive networks. It operates at 3.3V, making it compatible with modern low-power microcontrollers. The device adheres to the ISO 11898-2 standard, ensuring interoperability in CAN bus systems. As a key component in B2B industrial electronics, it bridges logic-level signals from microcontrollers to the differential signaling required by CAN buses. Its robustness against electromagnetic interference (EMI) and fault tolerance makes it a preferred choice for applications demanding reliability, such as vehicle diagnostics and factory automation.

Structure and Working Principle

The SN65HVD10D integrates a differential transmitter and receiver, along with protection circuits. The transmitter converts digital signals from a microcontroller into differential voltage pairs (CAN_H and CAN_L), while the receiver translates bus signals back to logic levels. Internally, it includes a dominant state timeout timer to prevent bus lockup during faults. The device also features thermal shutdown and bus pin protection (±36V), safeguarding against short circuits or miswiring. Its low-current standby mode (typ. 10µA) enhances energy efficiency in battery-operated systems.

Key Features

1. **Voltage Compatibility**: 3.3V operation aligns with energy-efficient designs, reducing power consumption compared to 5V alternatives. 2. **Fault Tolerance**: Withstands transient voltages up to ±36V on bus pins, critical for automotive environments. 3. **EMI Performance**: Meets stringent industrial EMC standards, minimizing interference in dense electronic assemblies. 4. **Speed**: Supports data rates up to 1Mbps, suitable for real-time control systems. Additional features include a wide operating temperature range (−40°C to +125°C) and compatibility with 3.3V/5V logic, offering design flexibility.

Application Areas

1. **Automotive**: Used in engine control units (ECUs), infotainment systems, and OBD-II ports for diagnostics. 2. **Industrial Automation**: Enables communication between PLCs, sensors, and actuators in Industry 4.0 setups. 3. **IoT Gateways**: Facilitates reliable data exchange in smart infrastructure and agricultural telemetry. Its small footprint (SOIC-8 package) allows integration into space-constrained designs, while its robustness suits outdoor or high-vibration environments.

Maintenance and Precautions

To ensure longevity, avoid exposing the SN65HVD10D to voltages exceeding its specified limits. Proper PCB layout is essential—route CAN bus traces as a matched pair to maintain signal integrity. For ESD protection, use TVS diodes on bus lines. Regularly inspect termination resistors (typically 120Ω) to prevent signal reflections. In automotive applications, conformal coating may be necessary to protect against moisture and contaminants.

B2B Procurement Guide

1. **Volume Discounts**: Prices drop significantly for orders exceeding 1,000 units; negotiate with distributors like Digi-Key or Mouser. 2. **Lead Time**: Stock availability varies; TI’s official website provides real-time updates. 3. **Alternatives**: Compare with similar transceivers like MCP2562 (Microchip) or TJA1050 (NXP) for cost-performance trade-offs. 4. **Certifications**: Ensure the part meets AEC-Q100 for automotive use if required. Always request samples to validate performance in your specific application before bulk purchases.
