MAX3031EEUE+T

Overview

The MAX3031EEUE+T is a quad RS-422 transmitter from the MAX3030E–MAX3033E family, designed for digital data transmission over twisted-pair balanced lines. It operates on a single +3V to +3.6V supply with low static current consumption of less than 100µA. The device guarantees a maximum data rate of 2Mbps and features slew-rate limiting to minimize electromagnetic interference. It provides ±15kV ESD protection on driver outputs and includes hot-swap functionality to prevent false transitions during power-up or insertion. The component is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Slew-rate-limited 2Mbps data rate minimizes EMI and reflections
• Hot-swap capability eliminates false transitions during power-up
• ±15kV ESD protection on all transmitter outputs
• Low-power design suitable for battery-operated applications

Applications

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

Procurement Notes

Verify the specific suffix EEUE+T corresponds to the industrial temperature grade (-40°C to +85°C) and the 16-pin TSSOP package configuration. Confirm that the ordering information matches the exact pinout requirements for your circuit design, as the MAX3031E variant utilizes global enable pins compatible with the 26LS31 standard rather than the dual-enable SN75174 pinout found in other family members.

Selection Notes

Select this component when a guaranteed 2Mbps data rate with slew-rate limiting is required to reduce signal reflections and EMI. It is appropriate for designs needing industry-standard pinouts compatible with the 26LS31. Ensure the application benefits from the integrated hot-swap feature to protect against bus contention during board insertion. Verify that the 16-pin TSSOP footprint fits the available PCB space constraints.

Part Context

This part belongs to the MAX3030E–MAX3033E family of quad RS-422 transmitters manufactured by Analog Devices / Maxim Integrated. These devices serve as low-power, ESD-protected upgrades to the industry-standard 26LS31 and SN75174. The family offers options for both 2Mbps and 20Mbps baud rates across various packages, with the MAX3031E specifically providing the slew-rate-controlled 2Mbps performance.

Replacement Considerations

Direct replacements within the same family include MAX3031ECSE (SO package), MAX3031ECUE (commercial temp), and MAX3031EESE (SO package). Cross-family alternatives like the MAX3044EEUE+T offer similar quad RS-422/RS-485 capabilities but may differ in voltage levels or speed specifications.
