MAX13431EEUB+

Drivers, Receivers, Transceivers Overview

The MAX13431EEUB+ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 10-pin µMAX package. It operates with a VCC supply voltage ranging from +3V to +5.5V and supports a low-voltage logic interface (VL) from +1.62V to VCC. The device features an unrestricted driver slew rate, enabling data transmission up to 16Mbps. It includes thermal shutdown protection, hot-swap input structures on DE and RE pins, and enhanced ESD protection for RS-485 I/O pins rated at ±30kV Human Body Model. The receiver input impedance is 1/8-unit load, allowing up to 256 transceivers on the bus.

Drivers, Receivers, Transceivers Feature Summary

• Adjustable low-voltage logic interface for direct interfacing with low-voltage ASICs or FPGAs without extra components
• Unrestricted driver slew rate supporting high-speed data transmission up to 16Mbps
• Hot-swap capability on DE and RE inputs to eliminate false transitions during power-up or insertion
• Enhanced ESD protection on RS-485 I/O pins meeting IEC 61000-4-2 standards

Drivers, Receivers, Transceivers Applications

• Industrial Control Systems
• Portable Industrial Equipment
• Motor Control
• HVAC Systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix EEUB+ corresponds to the 10-pin µMAX package variant when sourcing. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the component meets the extended operating temperature range of -40°C to +85°C required for the application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485 applications requiring high data rates up to 16Mbps. It is suitable for multivoltage systems due to the adjustable VL interface. Consider the 10-pin µMAX package for space-constrained designs. Verify that the system does not require full-duplex communication, which would necessitate the MAX13433E series instead.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13430E–MAX13433E family of RS-485 transceivers. The MAX13431E variant specifically provides half-duplex operation with unrestricted slew rates. It shares the same low-voltage logic interface and ESD protection features as the rest of the family but differs from the MAX13430E/MAX13432E which feature reduced slew rates for lower EMI at 500kbps.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13430EEUB+ is a functional substitute within the same package if lower data rates are acceptable. For full-duplex requirements, the MAX13433EEUB+ is the corresponding high-speed alternative. Cross-referencing pinouts confirms compatibility within the 10-pin µMAX form factor.
