MAX3031EEUE+

Overview

The MAX3031EEUE+ 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 provides ±15kV ESD protection on driver outputs and includes hot-swap functionality to prevent false transitions during power-up. The component is housed in a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Slew-rate-limited 2Mbps data transmission for reduced EMI
• Hot-swap capability prevents false transitions during insertion
• ±15kV Human Body Model ESD protection on outputs
• Low-power design suitable for battery applications

Applications

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

Procurement Notes

Verify the specific suffix EEUE corresponds to the extended temperature range (-40°C to +85°C) and the 16-pin TSSOP package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring quad differential drivers with low electromagnetic interference due to its controlled slew rates. It serves as a pin-compatible upgrade to industry-standard 26LS31 devices, ensuring compatibility with existing layouts while offering enhanced ESD protection and lower power consumption.

Part Context

This part belongs to the MAX3030E–MAX3033E family of quad RS-422 transmitters. While other variants in the series offer 20Mbps speeds, the MAX3031E specifically provides 2Mbps operation with slew-rate limiting. It shares the same physical footprint and pinout as the MAX3030E, MAX3032E, and MAX3033E models.

Replacement Considerations

Publicly confirmed substitutes include the MAX3030EEUE+, MAX3032EEUE+, and MAX3033EEUE+. These parts share identical pinouts and packages but differ in data rate capabilities (20Mbps vs 2Mbps). Verify that the system timing requirements align with the selected variant's speed specifications.
