Overview

The SN65HVD233QDRQ1 is a 3.3 V CAN bus transceiver from Texas Instruments with automotive (Q1) qualification. It implements the physical layer interface between a CAN controller (logic-level TX/RX) and the differential CAN bus, providing the required bus drivers and receivers for CAN networks. The device is intended for use in automotive and other harsh-environment CAN systems.

Why Choose This Part

Choose this part when you need an automotive-qualified 3.3 V CAN physical-layer device that directly interfaces to modern microcontrollers and CAN controllers. Its Q1 automotive grade provides higher confidence for in-vehicle deployments, and the 3.3 V logic compatibility avoids level-shifting when used with common MCUs and SoCs. Using a dedicated transceiver like this simplifies meeting CAN bus physical-layer requirements and improves robustness on shared vehicle networks.

Applications

Automotive body and chassis networks
Gateway and body-control modules that require an AEC-Q100-qualified CAN physical layer device.
Telematics and vehicle diagnostics
On-board telematics units and diagnostic adapters that interface with the vehicle CAN bus.
Industrial CAN networks (CANopen, DeviceNet)
Industrial controllers and sensor networks that need a robust 3.3 V CAN transceiver.
Motor controllers and inverters
Motor drive electronics that communicate status and commands over CAN.
CAN-based test and measurement tools
CAN bus sniffers, loggers, and bench interfaces requiring automotive-grade transceivers.

Getting Started

Interface the transceiver TXD and RXD pins to the CAN controller or MCU CAN peripheral; place the recommended 120 ohm termination resistor(s) at the bus ends and follow TI's layout and protection recommendations in the datasheet and application notes. Use a CAN-capable MCU, a USB-CAN adapter, or a CAN analyzer to exercise and monitor the bus. Verify supply decoupling, ESD/protection measures, and thermal requirements for automotive installations.
