MC33399D - LIN Bus Half Transceiver | NXP | Automotive
MPN: MC33399D ✓ सक्रियMC33399D अवलोकन
A LIN bus is a low-cost, single-wire communication network commonly used between automotive electronic control units. The MC33399D provides the physical interface needed to connect a host controller or microcontroller to that network. Its half-duplex arrangement supports bidirectional communication over the LIN conductor while allowing the host-side logic to manage request and response sequencing. The NXP listing identifies the part as an automotive LIN physical-layer transceiver, and a verified technical result associates it with the LIN transceiver category and AEC-Q100 automotive qualification.
The MC33399D is supplied in an 8-SOIC package according to DigiKey, while distributor information specifies a body width of 0.154 inches, or 3.90 mm. This surface-mount format supports compact automotive electronic modules while retaining a widely used package family. The product is intended for vehicle electronic control units, body electronics, sensor interfaces, door modules, lighting controllers, and other low-speed distributed automotive systems.
The primary design consideration is that LIN transceivers operate in a physically different environment from conventional high-speed interfaces. The bus is slower than CAN or Ethernet, but its single-wire topology, long cable runs, automotive transients, ground offsets, and shared-network behavior require careful PCB implementation. The transceiver should be placed near the connector or protected interface path, with its external protection and bus-connection components selected using the manufacturer datasheet and the vehicle platform requirements.
Because the supplied web evidence establishes the MC33399D identity, interface role, automotive qualification association, and 8-SOIC package, but does not provide complete electrical limits, timing values, pin names, or a verified numeric price, those details remain intentionally unasserted. Engineers should download the manufacturer datasheet and validate absolute maximum ratings, supply limits, logic thresholds, LIN bus parameters, termination, protection, and recommended external components before schematic or PCB release.
This page combines verified distributor information, source-traceable specifications, procurement guidance, interface-design considerations, and clearly qualified replacement analysis. It distinguishes documented facts from unavailable parameters so that an MC33399D design decision can be made without turning unverified values into engineering assumptions.

सामान्य अनुप्रयोग
MC33399D के लिए उपयुक्त है 6 अनुप्रयोगs: Automotive Body Control Module, Vehicle Door Control Module, Automotive Lighting Controller, Automotive Sensor Interface, Seat and Convenience-Control Module, HVAC Control Network Node.
Automotive Body Control Module
The MC33399D fits an automotive body-control module because the verified listings identify it as a half-duplex LIN physical-layer transceiver in an 8-SOIC package. A host microcontroller can connect through the transceiver to a single-wire LIN subnet for switches, locks, seat controls, or other distributed body functions. The 8-SOIC format allows placement near the connector or protected bus-entry area without requiring a large package. Because the supplied evidence does not disclose supply voltage, data rate, temperature range, or transient ratings, the implementation must be checked against the NXP datasheet and the vehicle's EMC requirements before production release.

Vehicle Door Control Module
A door-control module can use the MC33399D when a LIN subnet connects the latch or window electronics to a central body controller. The verified one-transceiver, half-duplex LINbus description supports host-side communication over a single-wire bus, while the 8-SOIC package supports conventional surface-mount assembly. The transceiver should be positioned near the harness or connector protection network so the external bus path remains short. Verify the exact TXD and RXD logic levels, wake-up behavior, operating temperature, and transient immunity against the NXP datasheet and the platform electrical specification.
अनुशंसित
Automotive Lighting Controller
The MC33399D can support a LIN-connected lighting controller where a central body ECU commands lamps or a lamp module through a low-cost single-wire network. Using a physical-layer transceiver isolates the host controller's logic signals from the LIN bus interface and organizes communication around request-and-response sequences. The verified 8-SOIC package is suitable for compact electronic modules, but illumination hardware still requires its own switching and protection circuitry. Check bus timing, supply limits, standby current, and fault behavior in the manufacturer datasheet before selecting the device for a lighting ECU.
अनुशंसित
Automotive Sensor Interface
The MC33399D is applicable to a remote sensor interface that communicates over a LIN subnet. Its verified identity as a physical-layer transceiver supports a host MCU's bidirectional communication with remote sensors or actuator nodes using the single-wire bus. The half-duplex arrangement requires the application firmware to manage request and response timing, so communication latency must be checked against the sensor update schedule. Exact baud-rate support, logic thresholds, standby behavior, and protection ratings are unavailable in the supplied excerpts and must be validated from NXP documentation before implementation.
अनुशंसित
Seat and Convenience-Control Module
A seat or convenience-control module can use the MC33399D to join a LIN network serving motors, switches, position sensors, and occupant-related functions. The compact 8-SOIC package leaves board area for the power stage and protection components, while the single-transceiver architecture fits a node that participates in bus communication rather than acting as a separate network hub. Firmware must account for half-duplex operation and deterministic response timing. Before schematic approval, compare the device's verified identity with all electrical and automotive requirements listed in the manufacturer datasheet and module validation plan.
अनुशंसित
HVAC Control Network Node
The MC33399D is suitable for an HVAC control node when a vehicle architecture distributes climate-control commands over LIN. The verified half-duplex LINbus interface allows a host controller to exchange data with actuator modules, and the 8-SOIC package supports automated PCB assembly in a compact electronic control unit. Designers should keep the bus path separated from switching power stages and motor-control traces, and should use the manufacturer's recommended protection arrangement. Supply range, bus rate, sleep current, temperature limits, and fault-recovery behavior are not supplied and remain mandatory datasheet checks before design release.

डिज़ाइन नोट्स
Place the MC33399D close to the LIN connector or protected bus-entry section. The verified evidence establishes an 8-SOIC package but does not provide the manufacturer layout, so follow the exact NXP datasheet for pin placement and external components. Keep the LIN route away from switching nodes, high-current motor returns, and sensitive analog inputs. A short bus connection reduces exposure to coupled noise, while a controlled ground reference helps the interface operate correctly across the vehicle harness environment.
Do not treat a shared 8-SOIC package as proof that every family variant is electrically interchangeable. The verified MC33399D data confirms one half-duplex LIN transceiver and an automotive application, but it does not expose individual pin functions, supply limits, thresholds, or timing. Before substituting MC33390D, MC33391D, MC33392D, MC33394D, or MC33398D, compare every pin, power rating, bus timing parameter, sleep mode, and automotive qualification in the manufacturer datasheets.
Use the manufacturer's recommended LIN protection and bus-interface network, and keep the connector-to-transceiver path short. Automotive wiring introduces transients and ground-potential differences, so the selected external devices must satisfy the vehicle's ESD, pulse, and EMC requirements. Decouple the transceiver supply at its pins according to the NXP datasheet and provide a low-impedance return path. Validate the assembled design with the platform EMC plan because the supplied excerpts do not provide numeric transient ratings.
Confirm the vehicle battery transient profile, nominal supply range, sleep current, and regulator behavior against the exact MC33399D datasheet. Those electrical values were not available in the supplied web excerpts, and an automotive nominal 12 V or 24 V rail should not be treated as proof of safe operating limits. Also determine whether the module requires wake-up through the LIN bus, TXD, or another control signal before finalizing the host firmware and power-management architecture.
