MAX13089EESD+T

Drivers, Receivers, Transceivers Overview

The MAX13089EESD+T is a +5.0V RS-485 transceiver featuring one driver and one receiver in a 14-pin SO package. It supports selectable data rates of 250kbps, 500kbps, and 16Mbps via the SRL pin. The device operates within a supply voltage range of 4.5V to 5.5V and draws 1.2mA of supply current. It provides ±15kV ESD protection on I/O pins and includes fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The part supports both half-duplex and full-duplex modes through the H/F pin.

Drivers, Receivers, Transceivers Feature Summary

• Pin-selectable operation for half-duplex or full-duplex communication modes
• Programmable slew rate limiting for data rates up to 16Mbps
• Hot-swap capability on DE and RE inputs to prevent false transitions during bus insertion
• Independent phase control pins for correcting twisted-pair reversal

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Telecommunications Equipment
• Profibus Networks

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESD' corresponds to the required temperature range (-40°C to +85°C) and packaging format (Reel/Cut Tape). Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering information matches the exact datasheet revision to validate electrical characteristics and pin configurations before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when flexible data rate configuration between 250kbps and 16Mbps is required. The MAX13089E is suitable for designs needing independent control over transmitter and receiver phases. It is appropriate for applications requiring hot-swap protection and fail-safe behavior on RS-485 buses without sacrificing high-speed performance capabilities.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of +5.0V RS-485 transceivers manufactured by Analog Devices/Maxim Integrated. While other family members offer fixed data rates or specific duplex modes, the MAX13089E provides unique configurability for both speed and duplex operation through dedicated selector pins.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same family include MAX13086E for fixed 16Mbps full-duplex operation and MAX13083E for fixed 500kbps full-duplex operation. Verify pin compatibility and thermal requirements when replacing with these variants.

Drivers, Receivers, Transceivers FAQ

How is the data rate selected on the MAX13089E?

The data rate is selected via the SRL pin: leave unconnected for 250kbps, connect to VCC for 500kbps, or connect to GND for 16Mbps.

What is the function of the H/F pin?

The H/F pin selects the communication mode; connecting it to VCC enables half-duplex operation, while connecting it to GND or leaving it unconnected enables full-duplex operation.

Does the MAX13089E support hot-swap insertion?

Yes, the DE and RE inputs feature hot-swap capability to eliminate false transitions on the bus during power-up or hot insertion.
