MAX13089EASD+

Drivers, Receivers, Transceivers Overview

The MAX13089EASD+ 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 from a 4.5V to 5.5V supply with a typical current of 1.8mA. It provides ±15kV ESD protection on I/O pins and includes fail-safe circuitry that guarantees a logic-high output when inputs are open or shorted. The part supports both half-duplex and full-duplex modes through the H/F pin and allows independent phase control for transmitter and receiver outputs.

Drivers, Receivers, Transceivers Feature Summary

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

Drivers, Receivers, Transceivers Applications

• Utility Meters
• Industrial Control Systems
• Profibus Networks
• Security Systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ASD+' indicates the -40°C to +125°C temperature range and 14-pin SOIC package configuration. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the ordering code matches the exact manufacturer part number to avoid functional discrepancies related to packaging or thermal ratings.

Drivers, Receivers, Transceivers Selection Notes

Select this component when variable transmission speeds are required within a single design. The MAX13089E is suitable for applications needing flexible bus topology support due to its selectable duplex mode. Verify that the system requires independent phase inversion capabilities to handle wiring errors without hardware changes.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of high-speed RS-485 transceivers manufactured by Analog Devices/Maxim Integrated. It shares core features like fail-safe operation and hot-swap inputs with siblings such as the MAX13080E and MAX13086E, but distinguishes itself through configurable speed and duplex settings.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other members of the MAX1308xE family, such as the MAX13086E for fixed 16Mbps full-duplex operation or the MAX13080E for fixed 250kbps full-duplex use. Cross-referencing pin compatibility and electrical characteristics is necessary when replacing non-configurable variants.
