About Texas Instruments

Texas Instruments (TI) stands as a global semiconductor leader with over 90 years of innovation in analog and embedded processing technologies. Their components are renowned for industrial-grade reliability, rigorous quality testing, and longevity in critical applications.

TI’s CAN transceiver portfolio sets industry standards for electromagnetic compatibility (EMC) and electrostatic discharge (ESD) protection. Their commitment to documentation and design resources simplifies implementation, making TI ICs a preferred choice for automotive and industrial engineers worldwide.

About CANbus Transceivers

CANbus transceivers serve as critical interface components between microcontrollers and physical communication buses in networked systems. They convert digital signals to differential bus voltages while providing electrical isolation and noise filtering.

In industrial and automotive applications, these ICs enable real-time data exchange between distributed electronic control units (ECUs). Their fault-tolerant design ensures continued operation despite wiring shorts or electromagnetic interference, making them essential for safety-critical systems like engine controls and medical devices.

Packaging Options

Available in industry-standard formats for automated assembly:

• Tape & Reel (TR)
• Cut Tape (CT)
• Digi-Reel®

Frequently Asked Questions

Q: Is this compatible with 5V microcontrollers?
A: Yes, when used with 3.3V logic via level-shifting resistors as shown in TI’s application notes.

Q: Does it support partial networking for power savings?
A: No, the SN65HVD234DR operates in classic CAN mode. For partial networking, consider TI’s TCAN33x family.

Q: What’s the maximum cable length at 1Mbps?
A: Up to 40 meters when using ISO 11898-2 compliant twisted-pair cabling.

Q: Are termination resistors required?
A: Yes, 120Ω resistors must be installed at both ends of the CAN bus per standard implementation.

Q: Can this interface with 3.3V DDR3L memory systems?
A: While sharing the same voltage range, it’s designed for communication buses – not direct memory interfacing.

Q: Is automotive qualification available?
A: This industrial-grade version (SN65HVD234DR) operates at -40°C to 125°C. For full AEC-Q100 qualification, request the SN65HVD234-Q1 variant.
