MAX13089EASD+T

Drivers, Receivers, Transceivers Overview

The MAX13089EASD+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 from a 4.5V to 5.5V supply with a typical current of 1.8mA. It includes ±15kV ESD protection, fail-safe circuitry, and hot-swap inputs on DE and RE. The part supports both half-duplex and full-duplex modes via the H/F pin, with independent phase control for TXP and RXP.

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
• Hot-swap capability on Driver Enable (DE) and Receiver Enable (RE) pins
• Independent transmitter and receiver phase inversion controls

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging and temperature range. Confirm RoHS compliance status directly with the manufacturer or authorized distributors before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when flexible duplex mode switching and high-speed transmission are required. Ensure the application utilizes three-state drivers for the SRL, H/F, TXP, and RXP control pins to properly configure the operating parameters.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of +5.0V RS-485 transceivers. It shares core features like fail-safe receivers and ESD protection with siblings such as the MAX13080E and MAX13086E, but offers unique programmability for speed and duplex configuration.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13089EEPD+ is a verified lead-free PDIP alternative within the same family. Verify that the replacement package matches the PCB footprint requirements.

Drivers, Receivers, Transceivers FAQ

How is the data rate selected on the MAX13089E?

The data rate is selected by driving 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 unselected enables full-duplex operation.

Does the MAX13089E support hot-swap insertion?

Yes, the DE and RE inputs feature internal pull-down/pull-up circuits that prevent erroneous data transfer during board insertion or power-up sequences.
