Overview

The TCAN334DR is a 3.3V CAN transceiver designed to provide an interface between a CAN protocol controller and the physical bus. It supports data rates up to 1Mbps and is fully compatible with the ISO 11898-2 standard while operating from a lower voltage supply than traditional 5V transceivers.

Why Choose This Part

The primary advantage is the 3V to 3.6V supply range, which eliminates the need for 5V level shifters or dedicated 5V regulators in modern 3.3V MCU designs. It also features 120 mV receiver hysteresis for improved noise immunity and a wide operating temperature range from -40degC to 125degC.

Applications

Industrial Automation
Used in factory floor equipment and programmable logic controllers (PLCs) where a 3.3V system rail is preferred.
Battery Powered Systems
Ideal for portable devices and mobile robotics that utilize 3.3V power architectures to reduce component count.
Automotive Diagnostics
Integration into 3.3V vehicle sub-systems requiring robust differential signaling and fault protection.

Also Consider

TCAN332DR TITexas Instruments - Select this version if you require an integrated shutdown mode for even lower standby power consumption.
MCP2561-E/SN MCHPMicrochip - A common alternative if your design can accommodate a standard 5V supply for the CAN transceiver.
SN65HVD230DR TITexas Instruments - An older, widely used 3.3V CAN transceiver that is often preferred for legacy compatibility in existing designs.
