MAX3089EEPD+

Overview

The MAX3089EEPD+ is a ±15kV ESD-protected, fail-safe, high-speed RS-485/RS-422 transceiver in a 14-pin Plastic DIP package. It operates from a single +5V supply (4.75V to 5.25V) and draws 375µA typical quiescent current. The device features one driver and one receiver with selectable half/full-duplex operation via the H/F pin. Slew rate is programmable between 115kbps, 500kbps, and 10Mbps using the SRL pin. Independent phase control for transmitter (TXP) and receiver (RXP) allows correction for twisted-pair reversal.

Feature Summary

• Pin-compatible with industry-standard 75180 devices while adding enhanced configuration capabilities
• Programmable slew-rate limiting enables error-free data transmission across multiple baud rates
• True fail-safe receiver guarantees logic-high output when inputs are open or shorted
• Independent phase inversion pins correct signal polarity errors caused by reversed twisted-pair connections

Applications

• RS-422 and RS-485 communication networks
• Industrial-control local area networks
• Level translators for EMI-sensitive applications

Procurement Notes

Verify the specific suffix 'EPD+' corresponds to the 14-pin Plastic DIP package and -40°C to +85°C temperature range. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when pin compatibility with standard 75180 interfaces is required alongside flexible duplex and speed configurations. Ensure the application utilizes a single +5V power supply and requires independent control over transmitter and receiver signal phases.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers manufactured by Analog Devices Inc./Maxim Integrated. The series provides robust ESD protection and fail-safe functionality for serial communication buses operating at various data rates up to 10Mbps.

Replacement Considerations

The MAX3089EEPD+ is pin-compatible with the industry-standard 75180 transceiver. Verify that substitute components support the required 14-pin DIP package and offer equivalent ESD protection levels.
