SP485CN-L/TR

Drivers, Receivers, Transceivers Overview

The SP485CN-L/TR is a low-power half-duplex RS-422/RS-485 transceiver manufactured by MaxLinear. It integrates one driver and one receiver in an 8-SOIC package. The device supports data rates up to 5 Mbps with a supply voltage range of 4.75 V to 5.25 V. It operates within a commercial temperature range of 0°C to +70°C. Key electrical specifications include a quiescent current of 300 µA, a shutdown current of less than 10 µA, and a differential output voltage of at least 1.5 V. The receiver features a 10 mV hysteresis for noise immunity.

Drivers, Receivers, Transceivers Feature Summary

• Low-power operation with dedicated shutdown mode for energy conservation
• High electromagnetic interference (EMI) immunity through slew-rate controlled drivers
• Fail-safe receiver design ensures a high logic state when the bus is idle
• Compliant with TIA/EIA-485-A standards for reliable data transmission

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation and security networks
• Multi-drop communication buses
• Point-to-point serial communication links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L/TR' confirms the tape-and-reel packaging format required for automated surface-mount assembly. Confirm that the commercial temperature grade (0°C to +70°C) aligns with the operational environment requirements. Ensure compatibility with existing 5V power rails before integration into the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring standard 5V operation and moderate data rates up to 5 Mbps. It is suitable for cost-sensitive designs where low standby power is critical. Compare against industrial-grade variants if extended temperature ranges are necessary. Verify pinout compatibility with legacy RS-485 footprints during PCB layout.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP485 family of half-duplex transceivers from MaxLinear. It serves as a surface-mount alternative to through-hole versions like the SP485CN-L. The device is designed to replace older generation RS-485 chips while maintaining pin compatibility and functional equivalence for standard industrial interfaces.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives include the ADM485ARZ from Analog Devices. Other potential substitutes within the same family may offer different temperature grades or packaging options.
