MAX13089EESD+

Drivers, Receivers, Transceivers Overview

The MAX13089EESD+ 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, and operates in half-duplex or full-duplex modes selected by the H/F pin. The device provides ±15kV ESD protection on I/O pins, fail-safe circuitry ensuring a logic-high output when inputs are open, and hot-swap capability on DE and RE inputs. Operating supply voltage ranges from 4.5V to 5.5V with a typical quiescent current of 1.2mA.

Drivers, Receivers, Transceivers Feature Summary

• Pin-selectable data rates for flexible system design
• Configurable half-duplex and full-duplex operation modes
• Integrated hot-swap input structures prevent bus errors during insertion
• Fail-safe receiver guarantees high output under undefined conditions

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESD+' indicates a lead-free and RoHS-compliant package configuration. Confirm the operating temperature range matches the 'EE' designation (-40°C to +85°C). Ensure the 14-pin SOIC package dimensions align with the target PCB layout requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when variable transmission speeds are required within a single design. The MAX13089E allows optimization for either low electromagnetic interference at slower speeds or high throughput at faster rates through external pin configuration. Verify that the application requires both phase control and duplex selection features not available in fixed-function variants.

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. Unlike other members of the series which have fixed data rates and duplex modes, the MAX13089E offers programmable slew rates and configurable communication directions to accommodate diverse interface requirements.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional replacements include MAX13086EESD+ for fixed 16Mbps full-duplex applications, or MAX13083EESD+ for fixed 500kbps full-duplex use. Note that these substitutes lack the pin-selectable speed and duplex features of the MAX13089E.

Drivers, Receivers, Transceivers FAQ

How is the data rate configured on the MAX13089E?

The data rate is set via the SRL (Slew-Rate Limit) pin. Connecting SRL to VCC selects 500kbps, leaving it unconnected selects 250kbps, and connecting it to GND selects 16Mbps.

What is the function of the H/F pin?

The H/F pin selects the communication mode. Driving it high configures the device for half-duplex operation, while driving it low or leaving it unconfigured sets it for full-duplex operation.

Does the MAX13089E support hot-swap capabilities?

Yes, the DE and RE inputs feature hot-swap circuitry that prevents false transitions on the bus during power-up or hot insertion into a powered backplane.
