MAX13485EESA+

Drivers, Receivers, Transceivers Overview

The MAX13485EESA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single +5V supply with a typical current consumption of 4.5 mA and supports data rates up to 500 kbps. The device features one driver and one receiver in an 8-pin SO package. It includes fail-safe circuitry, hot-swap capability, and ±15kV ESD protection on I/O 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 minimize electromagnetic interference and cable reflections
• 1/4-unit load receiver input impedance allows connection of up to 128 transceivers

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 suffix matches the required package type and lead-free status. Check for any regional distribution restrictions or obsolescence notices before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust EMI performance due to slew-rate limiting. Ensure the system operates within the specified +5V supply voltage. Consider the 1/4-unit load feature if high node counts are required on the bus. Verify thermal requirements against the extended industrial temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13485E/MAX13486E family of half-duplex transceivers. While the MAX13486E offers higher speeds without slew-rate limiting, the MAX13485E is optimized for error-free transmission up to 500kbps with reduced emissions. Both share similar pinouts and protective features.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13486EESA+ is a functional variant within the same family but lacks slew-rate limiting and supports higher speeds. Direct pin-compatible replacements should be verified against electrical specifications and package dimensions.
