CAN transceiver Texas Instruments SN65HVD234DR, 1 Tx/1 Rx, SOIC-8 package

The Texas Instruments SN65HVD234 is a CAN bus transceiver in an SOIC-8 package providing one transmit and one receive channel. It implements the physical-layer interface between a CAN controller and the bus, supporting standard CAN signaling for bidirectional data transfer. The device is designed for reliable communication in systems that use Controller Area Network protocols and is suitable for environments such as automotive networks, industrial control systems, and embedded platforms requiring a compact SOIC-8 form factor.

Advantages

The transceiver offers a compact SOIC-8 package and a 1 Tx / 1 Rx channel configuration that simplifies board layout and integration with microcontrollers and CAN controllers. It provides the electrical interface necessary for differential CAN signaling and is designed to operate within typical CAN network voltage and timing requirements. The component’s compatibility with standard CAN physical-layer specifications ensures predictable behavior when used with compliant controllers and bus topologies.

Suitable for

• Automotive body and body-control networks
• Industrial automation and machine control
• Embedded systems and microcontroller-based CAN nodes
• Prototyping and small-volume production of CAN devices

Key specifications

• Interface: Controller Area Network (CAN) physical layer transceiver
• Channels: 1 transmit (Tx) and 1 receive (Rx)
• Package: SOIC-8 surface-mount package
• Signal type: Differential CAN bus signaling (CAN_H / CAN_L)
• Data rates: Suitable for standard CAN data rates (depends on network design and bus length)
• Operating environment: Designed for automotive and industrial applications requiring robust bus connectivity

How to use

Place the SOIC-8 transceiver on the PCB according to recommended layout practices for CAN transceivers, keeping CAN_H and CAN_L traces paired and routing termination resistors at the ends of the bus. Connect the Tx input to the CAN controller transmit pin and the Rx output to the controller receive pin, following the controller vendor’s interface guidelines. Provide the correct supply voltage and ground connections, and include any recommended bypass capacitors close to the device supply pins. Ensure proper bus termination and common-mode considerations when integrating into an existing CAN network.

Recommendations

Follow automotive or industrial layout rules for signal integrity: place termination resistors close to the ends of the bus, keep differential traces matched in length, and include ESD protection and decoupling capacitors as recommended. Validate network operation at intended data rates and bus lengths during system testing.
