Overview

The TCAN334GDCNR is a 3.3V CAN transceiver designed to support high-speed CAN FD (Flexible Data Rate) up to 5Mbps. This component provides the physical layer link between a CAN protocol controller and the differential bus lines in systems with a 3.3V power supply rail.

Why Choose This Part

It eliminates the need for 5V regulators by operating directly on 3V to 3.6V supplies while maintaining compatibility with 5V CAN transceivers. The SOT-23-8 package saves significant board space compared to standard SOIC options, and it includes a 120 mV receiver hysteresis for improved noise immunity.

Applications

Industrial Automation
Used in factory control systems where a 3.3V supply is preferred over traditional 5V rails.
Building Automation
Provides reliable communication for HVAC and lighting control systems using CAN protocols.
CAN FD Networks
Ideal for modern networks requiring data rates up to 5Mbps for faster software downloads or high-throughput sensor data.

Getting Started

Integration requires a 3.3V supply and connection to a CAN controller TXD/RXD interface. Engineers should place a 100nF decoupling capacitor close to the VCC pin and ensure proper termination with 120-ohm resistors at the bus endpoints. For evaluation, use the TCAN33x EVM or similar CAN transceiver breakout boards for SOT-23-8 footprints.
