SP485ECN-L/TR

Drivers, Receivers, Transceivers Overview

The SP485ECN-L/TR is an enhanced low-power half-duplex RS-485 transceiver manufactured by MaxLinear, Inc. It supports data rates up to 10 Mbps 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 package with dimensions of 4.90 x 3.90 mm and a height of 1.65 mm. It functions reliably across a temperature range of 0°C to +70°C. Key electrical specifications include a propagation delay of 30 ns to 45 ns, a receiver hysteresis of 20 mV, and an output current capability of 250 mA. The component consumes 900 µA during operation and dissipates up to 500 mW.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced low-power design for efficient operation in battery-powered or energy-constrained systems.
• High electromagnetic interference (EMI) immunity through controlled slew rate mechanisms.
• Robust fault protection capabilities safeguarding the device against bus short circuits and overvoltage conditions.

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring reliable half-duplex communication.
• Building automation and control systems utilizing RS-485 protocols.
• Metering infrastructure including electricity and gas metering devices.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix configuration to ensure compatibility with required packaging formats such as tape and reel. Confirm that the operating temperature range meets the environmental constraints of the target application. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 10 Mbps data rate is required alongside low power consumption in a compact surface-mount package. Ensure the system voltage aligns with the 4.75 V to 5.25 V operating range. Consider the 0°C to +70°C industrial temperature rating against ambient conditions. Verify that the 8-SOIC footprint fits the printed circuit board layout constraints.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SP485E series of RS-485 interface integrated circuits from MaxLinear. It shares functional similarities with other members like the SP485EEN-L but differs in packaging and thermal specifications. The SP485ECN-L/TR specifically denotes the commercial temperature grade variant housed in an SOIC-8 tube or reel format, distinguishing it from extended temperature or alternative package options within the same product family.

Drivers, Receivers, Transceivers Replacement Considerations

The LTC1485IS8#TRPBF is listed as a substitute option. Verify pinout compatibility and electrical parameter alignment before implementation.
