TD341SCAN

Overview

The TD341SCAN is an isolated CAN transceiver housed in a DFN package. It complies with the ISO11898-2 standard and integrates a 3.3V power supply. The device supports I/O voltages of 3.3V and 5V for microprocessors, offering isolation withstand voltage up to 5000VDC. Bus electrostatic discharge protection reaches 15kV (HBM), with communication speeds up to 1Mbps. It provides bus fault protection from -40V to 40V and transient immunity exceeding 25kV/μs. The driver dominant timeout feature ensures safety, while low loop delay and support for up to 110 nodes are included. Operating temperature ranges from -40°C to +105°C, with MSL level 3.

Feature Summary

• Ultra-small, ultra-thin chip-level DFN packaging
• Integrated 3.3V high-efficiency power supply
• High isolation withstand voltage up to 5000VDC
• Robust bus electrostatic discharge protection up to 15kV (HBM)

Applications

• Industrial automation, control, sensor, and drive systems
• Building and greenhouse environmental control (HVAC) automation
• Security systems

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific part number matches the required DFN package and isolation specifications. Check for any recent certification status updates, as some related product lines have experienced temporary UL archive anomalies affecting post-dated certifications. Ensure compliance with RoHS standards before integration.

Selection Notes

Select this component when designing CAN networks requiring galvanic isolation between microprocessor domains and the bus. The integrated 3.3V regulator simplifies power architecture by eliminating external isolation supplies. Choose this model for applications demanding high ESD protection and wide common-mode range due to its -40V to 40V fault protection. Verify that the 1Mbps data rate and 110-node load capacity meet system requirements.

Part Context

This component belongs to a family of isolated interface devices designed for robust industrial communication. It complements other isolated transceivers like the TD341S485H, which serves RS-485 networks. Both share similar packaging and isolation characteristics but differ in protocol compliance, with this unit specifically optimized for CAN bus environments according to ISO11898-2.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult the manufacturer's official replacement guide or equivalent isolation transceiver datasheets for pin-compatible alternatives if this specific model becomes unavailable.
