SN65HVD230D Texas Instruments SN65HVD230D 3.3-V CAN Bus Transceiver

The Texas Instruments SN65HVD230D is a high-performance 3.3-V CAN bus transceiver designed to provide robust communication in industrial automation, automotive, and networking applications. This compact transceiver serves as the critical interface between a CAN protocol controller and the physical two-wire CAN bus, enabling reliable data transmission at up to 1 Mbps while maintaining compatibility with the ISO 11898-2 standard.

Engineered for harsh operating environments, the SN65HVD230D features industry-leading protection mechanisms including:

• ±16 kV HBM ESD protection on bus pins
• ±25 V common-mode transient protection
• Cross-wire, overvoltage, and loss-of-ground protection
• Thermal shutdown capability

The device operates from a single 3.3 V supply with a wide common-mode range of -2 V to 7 V, allowing seamless integration with 3.3 V microcontrollers and DSPs. Its intelligent power management system offers three operational modes controlled through the RS pin: high-speed mode (direct ground connection), slope control mode (adjustable with resistor), and standby mode (370 µA typical current).

Key Applications

• Industrial automation and process control systems
• Motor and robotic control units
• Building automation and HVAC equipment
• Telecom infrastructure and base stations
• Automotive subsystems and diagnostic tools
• CANopen, DeviceNet, and CAN Kingdom implementations

The SOIC-8 packaged transceiver supports up to 120 nodes on a single bus due to its high-impedance receiver inputs, while its glitch-free power-up/down characteristics make it ideal for hot-plug applications.

Frequently Asked Questions (FAQ)

1. What distinguishes the Texas Instruments SN65HVD230D 3.3-V CAN Bus Transceiver from competing devices?

Its ±16 kV HBM ESD protection, adjustable slew rate control, and three operational modes (including 370 µA standby) provide superior noise immunity and power flexibility compared to basic CAN transceivers.

2. How does the TI SN65HVD230D achieve reliable communication in electrically noisy environments?

The device features ±25 V common-mode rejection and cross-wire protection, while maintaining signal integrity through controlled driver transition times (adjustable via RS pin resistor).

3. What power saving features are available in the SN65HVD230D ICs?

The standby mode (370 µA typical) maintains bus monitoring capability while reducing power by 90% versus active mode. Unlike the SN65HVD231 (40 nA sleep), it preserves receiver functionality.

4. Can the Texas Instruments SN65HVD230D interface with 5V CAN controllers?

While designed for 3.3 V systems, it can interface with 5V logic through level-shifting buffers thanks to its 7 V common-mode tolerance, though direct 5V supply connection isn’t recommended.

5. What makes this transceiver suitable for industrial applications?

With extended -40°C to +85°C operation, thermal shutdown protection, and open-circuit fail-safe design, it withstands harsh conditions common in factory automation and motor control systems.

6. How many nodes can the SN65HVD230D ICs support on a single bus?

The high-impedance receiver inputs (typ. >50 kΩ) enable networks with up to 120 nodes, though practical limits depend on cable length and termination.
