MAX3031EESE+T

Overview

The MAX3031EESE+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 a maximum static current consumption of 100µA. The device supports a guaranteed 2Mbps baud rate and features slew-rate limiting to minimize electromagnetic interference. It provides ±15kV ESD protection on all outputs using the Human Body Model and includes hot-swap functionality to prevent false transitions during power-up or insertion. The component is housed in a 16-pin Narrow SO package.

Feature Summary

• Slew-rate-limited 2Mbps data rate to reduce EMI
• Hot-swap capability prevents false transitions
• ±15kV ESD protection on driver outputs
• Low-power design suitable for battery applications

Applications

• Telecom Backplanes
• V.11/X.21 Interface
• Industrial PLCs
• Motor Control

Procurement Notes

Verify the specific suffix EESE+T against the manufacturer's official documentation to confirm the -40°C to +85°C temperature range and the 16-pin Narrow SOIC package configuration. Ensure compatibility with existing board layouts by checking pin assignments against industry-standard 26LS31 and SN75174 equivalents. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a low-power, high-speed RS-422 transmitter is required for noisy environments. The MAX3031E variant is specifically chosen over the MAX3030E/3032E series due to its 2Mbps slew-rate-limited output, which minimizes reflections on improperly terminated cables. Verify that the system requires global enable control compatible with the 26LS31 pinout rather than the dual-enable SN75174 format.

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 industry-standard drivers. The family offers options for both 2Mbps and 20Mbps data rates, with the MAX3031E specifically providing the slower, slew-rate-controlled performance optimized for reducing electromagnetic emissions.

Replacement Considerations

Public confirmed substitutes include MAX3030EESE+T, MAX3032EESE+T, and MAX3033EESE+T within the same family.
