XR3087XEDTR-F

Drivers, Receivers, Transceivers Overview

The XR3087XEDTR-F is a half-duplex RS-485/RS-422 transceiver manufactured by MaxLinear. It operates from a single +5.0V supply with a typical quiescent current of 600μA and drops to approximately 300μA when idle. The device supports data rates up to 250kb/s and features an 18V tolerant bus interface capable of withstanding direct shorts. It includes full fail-safe circuitry, thermal shutdown, and short-circuit protection. The component is housed in an 8-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Provides 40% higher signal-to-noise ratio compared to standard RS-485/422 devices for improved noise margin.
• Bus pins tolerate direct shorts up to ±18V and offer ESD protection up to ±15kV.
• Includes hot swap circuitry to prevent false transitions during power-up or live insertion.

Drivers, Receivers, Transceivers Applications

• Industrial environments requiring high fault tolerance
• Profibus compliant communication networks
• Systems utilizing unterminated long data cables

Drivers, Receivers, Transceivers Procurement Notes

Verify the discontinuation status through official MaxLinear channels before design finalization. Confirm that the specific suffix matches the required package and temperature range. Request the latest Product Change Notice (PCN) to ensure no manufacturing changes affect compatibility. Validate RoHS compliance documentation directly with the manufacturer.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection on the RS-485 bus. The 18V tolerance makes it suitable for noisy industrial settings where voltage spikes are common. Ensure the system operates within the specified +5.0V supply constraints and does not require data rates exceeding 250kb/s.

Drivers, Receivers, Transceivers Part Context

This part belongs to the XR3080-88X family of high-performance transceivers designed for industrial reliability. The series emphasizes enhanced signal integrity and fault tolerance over standard interface solutions. It integrates advanced protection features to maintain operation under adverse electrical conditions.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the XR3080-88X family. Verify if other manufacturers offer equivalent 18V tolerant RS-485 transceivers with similar SNR improvements. Ensure any substitute maintains the same +5V supply requirement and SOIC-8 packaging.
