Overview

The TCAN334DCNR is a 3.3V CAN transceiver designed to provide high-speed CAN physical layer communication at data rates up to 1Mbps. It features both a low-power standby mode with wake-up capability and a dedicated shutdown mode to minimize energy consumption in battery-powered or green-energy applications. The device is housed in a compact 8-pin SOT-23 package, making it suitable for space-constrained industrial and automotive designs.

Why Choose This Part

The TCAN334DCNR offers significant space savings via its SOT-23-8 package while maintaining a wide operating temperature range of -40C to 125C. Its low-power architecture consumes only 20uA in standby and shutdown, and its unpowered behavior ensures high impedance on bus pins to prevent glitching during power-up cycles.

Applications

Industrial Automation
Used in factory automation systems where 3.3V microcontrollers require CAN connectivity for sensor and actuator networking.
Battery-Powered Systems
Utilizes the 20uA shutdown and standby modes to extend battery life in portable diagnostic tools and remote monitoring equipment.
Building Automation
Provides reliable CAN communication for HVAC control systems and lighting networks within commercial buildings.
Embedded Control Modules
Integrates into small-form-factor control boards that lack the space for traditional SOIC-packaged transceivers.
