Bus controller transceiver Texas Instruments SN65HVD231D — 1 driver, 1 receiver, SO-8

The Texas Instruments SN65HVD231D is a single-driver, single-receiver bus controller transceiver in an SO-8 package designed for differential bus interfaces. It implements robust transmit and receive functions suitable for automotive and industrial communication nodes, offering a compact board-level solution for serial bus connections and embedded control systems.

Advantages

The device provides a standard-compliant differential interface with electrical characteristics geared toward reliable data transmission in noisy environments. Its SO-8 packaging supports easy placement on PCBs and straightforward thermal management. The integrated driver and receiver reduce component count and simplify board-level design while maintaining signal integrity for short- to medium-distance bus links.

Suitable for

• CAN bus nodes and LIN gateways that require a single transceiver channel
• Embedded controllers and microcontroller interfaces for serial communication
• Industrial sensor networks and control systems with differential signaling
• Board-level serial bus connections where compact SO-8 footprint is needed

Key specifications

• Topology: one driver and one receiver in a single package
• Package type: SO-8 surface-mount
• Interface: differential bus transceiver for serial communications
• Operating environment: suitable for automotive and industrial communication nodes
• Signal direction: half-duplex or single-channel differential transmit/receive as required by bus protocol

How to use

Place the SO-8 transceiver on the PCB with attention to recommended signal routing and grounding to preserve differential pair integrity. Connect the driver/receiver pins to the differential bus lines and route control or enable signals to the host microcontroller according to the system’s communication protocol. Ensure supply voltage and decoupling capacitors meet the transceiver’s requirements and provide appropriate termination on the bus to minimize reflections.

Usage recommendations

For reliable operation, follow the bus protocol timing and termination guidelines, use short controlled-impedance traces for differential pairs, and add local decoupling close to the supply pins. Verify layout for thermal dissipation and keep a clear ground return path to reduce electromagnetic interference.
