MAX13085EESA+

Drivers, Receivers, Transceivers Overview

The MAX13085EESA+ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5.0V supply (4.5V to 5.5V) and supports data rates up to 500kbps with slew-rate-limited drivers. The device features ±15kV ESD protection, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and hot-swap capability on the DE and RE pins. It contains one driver and one receiver in an 8-pin SOIC package and operates within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap input structures on DE and RE pins prevent false transitions during power-up or bus insertion.
• True fail-safe receiver guarantees a logic-high output when receiver inputs are open or shorted while maintaining EIA/TIA-485 compatibility.
• Enhanced slew-rate limiting minimizes electromagnetic interference (EMI) and reduces reflections from improperly terminated cables.

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Telecommunications Equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official datasheets to confirm the specific suffix indicates lead-free and RoHS compliance. Ensure the ordering information matches the required package type and temperature range for your application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring half-duplex communication at speeds up to 500kbps. It is suitable for environments where bus insertion occurs while powered, due to its integrated hot-swap functionality. Verify that the 8-pin SOIC package fits the board layout constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13080E–MAX13089E family of +5.0V, ±15kV ESD-protected RS-485 transceivers. The family includes variants for full-duplex operation and different data rate capabilities, ranging from 250kbps to 16Mbps depending on the specific model number.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13084EESA+ is a full-duplex variant within the same family. Other models like the MAX13082E offer half-duplex operation but may differ in data rate specifications or pin configurations.
