SP485RCN-L

Drivers, Receivers, Transceivers Overview

The SP485RCN-L is a high-fanout RS-485 transceiver manufactured by MaxLinear. It supports data rates up to 5 Mb/s and operates within a supply voltage range of 4.75 V to 5.25 V. The device features one driver and one receiver in an 8-SOIC surface-mount package. It is designed for half-duplex communication and complies with RS-422 and RS-485 protocols. The component functions reliably across an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• High fanout capability supporting up to 32 unit loads on the bus
• Integrated fail-safe circuitry to ensure a high receiver output state during idle conditions
• Low power consumption design suitable for battery-operated applications

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building automation systems
• Multi-drop communication buses

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation, as this component was originally part of the Exar portfolio now managed by MaxLinear. Confirm the specific suffix indicates the SOIC-8 surface mount package and commercial temperature grade. Ensure RoHS compliance status matches current production requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a high unit load count is required compared to standard quarter-unit load devices. It is appropriate for designs needing 5 Mb/s speeds with a single 5V supply. Consider the 8-SOIC footprint for PCB layout constraints. Verify that the commercial temperature range meets the environmental specifications of the target application.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SP485 series of RS-485 transceivers. It shares functional similarities with other parts in the family but is distinguished by its high fanout specification. The transition from Exar to MaxLinear has maintained the core electrical characteristics while updating manufacturing sources.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements include the SP485CN-L for standard unit load applications. Other compatible options may include the ADM4850ARZ or LTC1485IS8#TRPBF, though these typically offer lower unit load counts. Verify interface compatibility and thermal performance when substituting.
