Overview

The TCAN334GDCNT is a 3.3V CAN transceiver capable of data rates up to 5 Mbps, supporting both standard CAN and CAN FD (Flexible Data Rate) protocols. It is designed to interface between a single-ended controller and the differential CAN bus in space-constrained industrial and automotive environments. The device features integrated protection including shutdown and standby modes to minimize system power consumption.

Why Choose This Part

This transceiver operates from a 3V to 3.6V supply, eliminating the need for 5V rails in 3.3V-only systems. It offers excellent EMC performance and a wide operating temperature range from -40C to 125C, making it suitable for harsh environments. The inclusion of a 2.5 uA shutdown mode and a 20 uA standby mode significantly extends battery life in portable or remote applications.

Applications

Industrial Automation
Used in PLC networks and factory floor control systems where 3.3V logic levels are required for modern microcontrollers.
Building Automation
Integrates into HVAC and security systems requiring robust differential signaling over long distances.
Sensor and Drive Systems
Ideal for motor control and remote sensor nodes that need high EMC performance and low-power standby modes.

Getting Started

To evaluate this part, use the TCAN33x evaluation module from Texas Instruments which allows for testing all functional modes and bus timings. Ensure the CAN bus is terminated with 120-ohm resistors at both ends of the network for signal integrity. Connect the TXD and RXD pins directly to a microcontroller CAN controller using 3.3V logic levels.
