L9669013TR - 1/1 Half CAN Transceiver | STMicroelectronics
料号： L9669013TR ✓ 量产中L9669013TR 概述
A CAN transceiver is an interface IC that connects a digital controller or microcontroller to a CAN bus. The CAN protocol uses differential signaling to provide noise immunity and reliable communication over longer cable runs than many single-ended interfaces. A 1/1 transceiver combines one transmitter and one receiver, while the word half indicates its position within the broader family of CAN interface devices with different driver and receiver counts.
The L9669013TR is identified in the product listings as an IC transceiver half 1/1 for CANbus, with a 14-SO package. The listed operating supply range is 4.75 V to 5.25 V, making the device suitable for systems using a regulated 5 V CAN interface rail. Its specified operating temperature range of -40°C to 150°C supports use across industrial temperature environments and automotive-oriented equipment.
The principal design consideration is ensuring that the transceiver supply, ground, signal, and bus connections match the host controller interface. CAN bus routing should be kept controlled, with attention to termination, protection, and grounding in the wider network. Because the exact pin assignment and electrical characteristics are not reproduced in the available product snippets, use the manufacturer datasheet for final pin connections and operating details.
Typical uses include CAN-based industrial control, vehicle communication modules, embedded instrumentation, and controller area network gateways. The surface-mount 14-SOIC format also allows the device to be integrated into compact control boards where a through-hole solution is not desirable.

典型应用
L9669013TR 适用于 6 应用s: Industrial CAN Control Module, Automotive Communication Module, Embedded CAN Gateway, Vehicle Diagnostic Interface, CAN-Based Sensor Network, Test and Measurement Instrument.
Industrial CAN Control Module
The L9669013TR is suitable for an industrial controller that needs to communicate over a CANbus with sensors, actuators, or remote equipment. Its 1/1 transceiver arrangement connects one CAN driver and one CAN receiver to the controller logic, while the 4.75 V to 5.25 V supply range aligns with a regulated 5 V interface rail. The 14-SOIC surface-mount package helps reduce board area in compact control equipment. Use the manufacturer datasheet to confirm timing, logic levels, bus loading, termination, and protection requirements before finalizing the circuit.
推荐
Automotive Communication Module
The L9669013TR can be used in an automotive communication module that requires a CANbus interface close to the host microcontroller or application processor. The listed -40°C to 150°C operating range is useful for vehicle environments, and the surface-mount 14-SOIC package supports compact electronic control units. The design must still verify automotive qualification, transient immunity, bus fault handling, and protection requirements. The manufacturer datasheet is the controlling reference for those electrical and qualification details.
推荐
Embedded CAN Gateway
A gateway between an embedded processor and a CAN network can use the L9669013TR as its physical-layer interface. The 1/1 configuration provides the required driver and receiver functions for a single CAN channel, while the 14-SOIC footprint allows straightforward assembly alongside digital logic. Route the differential bus according to the manufacturer's application guidance, include proper termination at the network ends, and evaluate protection for cables connected outside the enclosure. Confirm timing and fault behavior from the manufacturer datasheet.
推荐
Vehicle Diagnostic Interface
The L9669013TR is appropriate for a vehicle diagnostic interface that exposes a CANbus connection to a diagnostic controller. Its one-driver, one-receiver arrangement is suited to a single CAN channel, and the listed operating temperature range covers extended-temperature vehicle conditions. The PCB should preserve controlled bus geometry and include the required termination and protection components. Automotive qualification and exact transient specifications must be confirmed directly with the manufacturer rather than inferred from the temperature rating alone.
推荐
CAN-Based Sensor Network
The L9669013TR can interface a sensor or actuator controller to a CANbus-based industrial sensor network. Its 1/1 CANbus interface supports one communication channel, and the 4.75 V to 5.25 V operating supply range is compatible with regulated 5 V designs. The 14-SOIC surface-mount package is practical for compact sensor nodes and distributed I/O products. Validate the complete bus topology, termination, isolation strategy, grounding, and environmental requirements before deployment.
推荐
Test and Measurement Instrument
The L9669013TR can serve as the CANbus interface in a test instrument that communicates with industrial or vehicle test systems. The one-driver and one-receiver configuration provides a compact physical-layer endpoint for a single CAN channel, while the 14-SOIC package supports automated board assembly. Instrument designers should account for bus termination, fault injection, grounding, and protection when the interface connects to external cables. Use the manufacturer datasheet to verify logic thresholds, timing, and operating limits.

选型指南
设计说明
Use the 14-SOIC land pattern associated with the manufacturer's package drawing and place the transceiver close to the host controller and CAN connector. Keep the CANH and CANL pair routed together, minimize stubs and unnecessary loop area, and separate the bus routing from sensitive analog or high-speed digital signals. Confirm every pin function against the manufacturer pin-description table before releasing the PCB layout.
The listed operating supply range is 4.75 V to 5.25 V, so the device should be powered from a regulated 5 V rail. Place the input decoupling capacitance close to the supply and ground pins and maintain the manufacturer's recommended layout. Because the available product snippets do not state the required capacitor values or quiescent current, use the manufacturer datasheet for the final power-network design rather than estimating those values.
Do not treat a generic 14-pin SOIC as a verified substitute for this exact transceiver. Confirm the supply pins, CAN bus pins, logic reference, enable or standby functions, and exposed-pad requirements from the manufacturer datasheet. Also verify the complete CAN bus architecture: termination belongs at the physical ends of the bus, while transceiver protection must be matched to the cable length and industrial or automotive environment.
CAN is a differential bus, so the two signal traces should have controlled geometry and be routed as a pair. Preserve the intended network impedance with the specified termination arrangement, avoid unnecessary vias and branch stubs, and provide a low-impedance return path to the transceiver ground. For long cables or electrically noisy installations, evaluate isolation and surge protection according to the complete system requirements.
