AZRS3082

Drivers, Receivers, Transceivers Overview

The AZRS3082 is a half-duplex RS-485 transceiver designed for 5V power supply applications, fully compliant with EIA/TIA-485 standards. It features integrated transient voltage suppression providing ±30kV IEC 61000-4-2 protection on bus terminals, alongside ±15kV HBM and ±800V MM ESD protection. The device supports data rates up to 115kbps with controlled slew-rate limiting to minimize EMI. Key electrical characteristics include a 96kΩ receiver input impedance (1/8 unit load), enabling up to 256 devices on the bus. Operating temperature ranges from -40°C to +85°C, with shutdown current as low as 1nA.

Drivers, Receivers, Transceivers Feature Summary

• Integrated TVS protection for robust bus terminal defense against ESD, EFT, and surge events
• True fail-safe receiver guarantees logic high output during open, short, or idle bus conditions
• Hot-swap glitch protection maintains high-impedance state during power-up sequences
• Thermal shutdown and current limiting protect against system fault conditions

Drivers, Receivers, Transceivers Applications

• Energy meter networks
• Motor control systems
• Industrial control equipment
• Telecommunications infrastructure
• Security systems
• Building automation networks

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity by checking the marking code 'RS3082' followed by date and control codes on the SO-8 package. Confirm the ordering suffix matches specific packaging requirements such as tape and reel quantities. Ensure the supplier provides valid traceability documentation consistent with Amazing Micro manufacturing standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component for 5V RS-485 networks requiring high noise immunity and internal surge protection. The 1/8 unit load specification allows for extensive node expansion beyond standard limits. Ensure application environments remain within the specified -40°C to +85°C operating range for optimal performance.

Drivers, Receivers, Transceivers Part Context

This device belongs to the RS-485 transceiver family from Amazing Micro, focusing on industrial-grade reliability. It complements other interface solutions by offering integrated protection without external components. The SO-8 package facilitates compact PCB layouts for space-constrained embedded designs.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes must match the half-duplex topology, 5V operation, and SO-8 package. Verify that alternative components offer comparable ±30kV ESD protection and 1/8 unit load input impedance to maintain network compatibility.
