MAX3031ECUE+

Overview

The MAX3031ECUE+ is a quad RS-422 transmitter manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3V to +3.6V supply with a typical static current of 100µA. The device supports a maximum data rate of 2Mbps and features slew-rate limiting to minimize EMI. It includes ±15kV Human Body Model ESD protection, hot-swap capability, and thermal shutdown. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Slew-rate-limited 2Mbps operation minimizes electromagnetic interference and reflections
• Hot-swap functionality prevents false transitions during power-up or board insertion
• Enhanced ±15kV ESD protection on all driver outputs
• Low-power design suitable for battery-powered applications

Applications

• Telecom backplanes
• V.11/X.21 interface systems
• Industrial PLCs
• Motor control circuits

Procurement Notes

Verify the specific suffix 'UE+' corresponds to the 16-pin TSSOP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when a 2Mbps RS-422 data rate with controlled slew rates is required to reduce signal reflections. Ensure the application utilizes a 3.3V supply and requires hot-swap protection for backplane environments. Verify that the 16-pin TSSOP footprint matches the PCB layout constraints.

Part Context

This part belongs to the MAX3030E–MAX3033E family of quad RS-422 transmitters. It serves as a low-power, ESD-protected upgrade to industry-standard devices like the 26LS31. The MAX3031 variant specifically provides the 2Mbps baud rate option within this family.

Replacement Considerations

Pin-compatible replacements include other members of the MAX3030E–MAX3033E family, such as the MAX3030E or MAX3032E, provided the data rate requirements align with the specific variant's capabilities.
