MAX3441EESA+T

Overview

The MAX3441EESA+T is a single RS-485 transceiver in an 8-pin SO package. It operates from a 4.75V to 5.25V supply with a typical quiescent current of 10mA. The device supports data rates up to 10Mbps and features ±60V fault protection on the A and B pins, alongside ±15kV ESD protection. It includes true fail-safe inputs that guarantee a logic-high receiver output when inputs are open or shorted. Hot-swap circuitry prevents false transitions during bus connection.

Feature Summary

• Integrated hot-swap input structure prevents data bus disturbances during board insertion into live backplanes
• True fail-safe receiver design ensures a defined high logic state when differential inputs are open, shorted, or idle
• Robust ±60V fault protection withstands voltage faults on communication lines without requiring external components

Applications

• RS-422/RS-485 Communications
• Industrial Networks
• Telecommunications Systems
• HVAC Controls

Procurement Notes

Verify the component matches the specific MAX3441E variant which lacks slew-rate limiting for higher speeds. Confirm the + suffix indicates lead-free and RoHS compliance. Ensure the ESA suffix corresponds to the 8-pin Small Outline package. Cross-reference the manufacturer's latest documentation to confirm current production status and availability constraints.

Selection Notes

Select this model over the MAX3440E or MAX3442E when data rates exceeding 250kbps are required, as those variants feature enhanced slew-rate limiting. This part is suitable for applications needing fast transmission speeds up to 10Mbps while maintaining standard RS-485 compatibility and fault protection capabilities.

Part Context

This component belongs to the MAX3440E–MAX3444E family of fault-protected transceivers manufactured by Analog Devices / Maxim Integrated. The family shares common features like ±60V protection and fail-safe inputs but differs in data rate capabilities and driver slew-rate characteristics based on the specific model number.

Replacement Considerations

The MAX3443E is a functional substitute within the same family that offers low-power shutdown capability, whereas the MAX3441E does not support this mode. Other models like the MAX3440E provide slower data rates with slew-rate limiting.
