SP485ECN-L/TR Descripción general
A differential line transceiver is an interface IC that translates logic-level signals into balanced differential transmissions and converts received differential signals back into CMOS-compatible logic. In this product hierarchy, the SP485ECN-L/TR is a half-duplex RS-485/RS-422 transceiver within the interface IC and semiconductor categories. Half-duplex operation means the driver and receiver share the same bus pair, allowing a node to transmit or receive but not both simultaneously.
The verified product information identifies one driver, one receiver, a single 5 V supply, RS-485 protocol support, and an 8-SOIC package measuring 0.154 inches, or 3.90 mm, wide. MaxLinear states that the SP485 family supports RS-485 and RS-422 operation up to 5 Mbps, while comparison data for the -L ordering variant lists a 10 Mbps data rate. The enhanced ESD capability exceeds ±15 kV using both Human Body Model and IEC 61000-4-2 air-discharge methods.
BiCMOS implementation combines bipolar and CMOS characteristics to support low-power operation without sacrificing line performance. The SP485ECN-L/TR is suitable for industrial equipment, data acquisition, building controls, factory interfaces, and other balanced serial links where multidrop communications, noise immunity, and standardized protocol support are important. Its half-duplex architecture simplifies wiring but requires software or hardware coordination of transmit and receive states.
For PCB design, keep the transceiver close to the line connector and provide a low-return-path ground plane beneath and around the device. Route the balanced driver and receiver traces as a closely coupled differential pair with continuous reference planes and minimized stubs. The supplied data does not provide exact pin names, differential impedance recommendations, input capacitance, supply-current limits, or junction-temperature limits, so those values must be confirmed in the manufacturer datasheet before final release.
This page synthesizes verified distributor and manufacturer information, cross-reference evidence, pricing information, package details, and practical interface-design guidance. It distinguishes confirmed values from unavailable technical parameters and avoids treating the web-search cross-reference suggestions as guaranteed drop-in replacements without package and pinout verification.

Aplicaciones típicas
SP485ECN-L/TR es adecuado para 6 aplicacións: Industrial RS-485 Control Bus, Building Automation Network, Data Acquisition and Sensor Networking, Factory Automation Module Interface, Remote Instrumentation Link, Power and Energy Metering.
Industrial RS-485 Control Bus
The SP485ECN-L/TR fits industrial control and instrumentation buses that need a half-duplex differential interface in a compact 8-SOIC package. Its verified 10 Mbps position for the -L variant provides ample link margin for many controller-to-module connections, while the BiCMOS design supports low-power operation. Place the transceiver near the field connector, route the bus as a differential pair, and verify node count, cable length, termination, and industrial temperature requirements against the manufacturer datasheet.
Recomendado
Building Automation Network
For building-automation equipment, the SP485ECN-L/TR provides a low-power 5 V RS-485/RS-422 interface for sensors, actuators, and supervisory controllers. Half-duplex operation reduces wiring compared with separate full-duplex links, and the verified family data identifies one driver and one receiver for typical multidrop bus nodes. Designers should validate common-mode range, fail-safe behavior, ESD requirements, and the number of remote nodes before deploying it in a long building cable run.
Recomendado
Data Acquisition and Sensor Networking
The SP485ECN-L/TR can connect a controller to distributed sensors over a balanced, noise-resistant bus. The 10 Mbps verified rate is useful for burst-oriented acquisition, while the half-duplex arrangement simplifies one-pair field wiring. Keep the driver and receiver return path continuous, use biasing or termination appropriate to the network, and confirm input sensitivity and common-mode limits in the official datasheet. The supplied information does not state the full receiver threshold or noise performance, so those values remain release-review items.
Recomendado
Factory Automation Module Interface
The device is appropriate for PLC-adjacent modules, motor-control support circuitry, and factory peripherals that communicate over an RS-485 link. Its 5 V supply and 8-SOIC footprint support compact controller boards, while the family’s BiCMOS design targets low-power operation. For factory environments, combine the transceiver with correctly placed surge and ESD protection, a controlled ground reference, and a defined fault strategy. The verified enhanced ESD figure exceeding ±15 kV describes device-level protection positioning, not a complete industrial immunity certification.
Recomendado
Remote Instrumentation Link
Remote test and measurement instruments can use the SP485ECN-L/TR as a balanced host-to-instrument interface when a half-duplex protocol and shared bus pair are acceptable. The 10 Mbps capability supports high-speed command and measurement traffic, but sustained operation still depends on cable attenuation, node loading, and grounding. Verify the transceiver's electrical limits before release and place the line interface close to the connector to keep unprotected traces away from sensitive analog sections.
Recomendado
Power and Energy Metering
Energy meters, power-quality monitors, and distributed measurement cards can use the SP485ECN-L/TR for a compact two-wire RS-485 connection. Its low-power BiCMOS architecture is useful in multi-instrument installations where each node consumes limited power. The design must include correct termination, fail-safe biasing, and isolation strategy when nodes are separated by large ground-potential differences. Confirm operating temperature and common-mode limits from the manufacturer datasheet because those values are not present in the supplied web snippets.

Notas de diseño
Place the SP485ECN-L/TR close to the external RS-485 connector and route the A and B conductors as a tightly coupled differential pair over a continuous ground reference. Keep the differential pair away from switching nodes, clocks, and high-current return paths. Minimize test pads and branch stubs on the cable-side nets. The verified data identifies enhanced device ESD capability above ±15 kV, but that rating does not replace connector-side surge protection or a system-level EMC design.
Do not treat the SP485, SP485E, SP485CN, and SP485ECN-L order codes as automatically interchangeable. The supplied comparison lists 5 Mb/s for SP485CN-L and 10 Mbps for SP485ECN-L, while different suffixes may change enable, shutdown, temperature, or qualification details that are not specified here. Before a substitution, verify the complete pinout, supply limits, receiver thresholds, driver current, fail-safe behavior, and package drawing against the manufacturer datasheet.
Design the 5 V rail with local decoupling close to the transceiver and ensure the power source can support the device plus any external termination and protection components. The verified snippets identify a 5 V supply but do not state the numerical supply-current range, so the current budget must be completed from the official datasheet. Account for voltage tolerance, startup behavior, ground-return current, and any transceiver shutdown-control requirements in the system power budget.
Información de cumplimiento
The verified search data describes the product as lead-free but does not provide authoritative RoHS, REACH, halogen-free, AEC-Q100, or conflict-minerals statements. IEC 61000-4-2 appears in the verified ESD description and is retained as an ESD test method reference, not as a general compliance certification.
