MAX13485EELA+T

Drivers, Receivers, Transceivers Overview

The MAX13485EELA+T is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a +5V supply (4.75V to 5.25V) and features one driver and one receiver in an 8-pin µDFN package. The device supports data rates up to 500kbps with slew-rate limiting to minimize EMI. It includes fail-safe circuitry, hot-swap capability, and ±15kV ESD protection on A/B pins. Operating temperature range is -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Fail-safe receiver guarantees logic-high output when inputs are open or shorted
• Hot-swap capability prevents false transitions during live insertion or power-up
• Slew-rate limited drivers reduce electromagnetic interference and cable reflections
• 1/4-unit load receiver input impedance allows up to 128 transceivers on the bus

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Controls
• Industrial Motor Drives
• Automated HVAC Systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package type and lead-free status. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing any acquisition.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust communication over multipoint bus transmission lines where electromagnetic interference is a concern. The slew-rate limitation makes it suitable for longer cables or imperfectly terminated lines compared to high-speed variants. Verify that the system voltage aligns with the specified +5V requirement and that the thermal environment falls within the extended industrial range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13485E/MAX13486E family of half-duplex transceivers. The MAX13485E variant specifically incorporates slew-rate limiting for improved signal integrity at lower speeds, distinguishing it from the unrestricted MAX13486E. Both share similar pinouts and feature sets like fail-safe and hot-swap capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

MAX13486EELA+T offers identical packaging and features but without slew-rate limiting, supporting higher speeds up to 16Mbps.
