MAX3033EEUE/GG8

Overview

The MAX3033EEUE is a quad RS-422 transmitter operating from a +3V to +3.6V supply, featuring a guaranteed 2Mbps data rate with slew-rate limiting to minimize EMI. It provides ±15kV Human Body Model ESD protection on outputs and includes hot-swap functionality to prevent false transitions during power-up. The device operates within a -40°C to +85°C temperature range and consumes less than 100µA of static supply current. Packaged in a 16-pin TSSOP, it meets TIA/EIA-422-B and ITU-T V.11 standards.

Feature Summary

• Slew-rate-limited 2Mbps transmission minimizes electromagnetic interference and cable reflections.
• Integrated hot-swap capability prevents false data transitions during board insertion or power sequencing.
• Outputs withstand ±15kV electrostatic discharge stress using the Human Body Model.
• Low static current consumption supports battery-powered and power-sensitive designs.

Applications

• Telecom backplanes
• V.11/X.21 interface circuits
• Industrial programmable logic controllers (PLCs)
• Motor control systems

Procurement Notes

Verify the specific suffix EEUE confirms the extended temperature range (-40°C to +85°C) and TSSOP package type. Confirm RoHS compliance status for the specific manufacturing lot. Ensure the ordering quantity matches the tube packaging format specified by the manufacturer. Cross-reference the datasheet revision date to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a 2Mbps baud rate with controlled slew rates is required to reduce signal integrity issues. Choose this part over the MAX3030E/MAX3032E family if lower electromagnetic emissions are critical compared to higher speed requirements. Verify that the dual enable pin configuration (EN1&2, EN3&4) aligns with the system's control logic needs.

Part Context

This device 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 and SN75174. The MAX3033E variant specifically offers the 2Mbps slew-rate-limited performance, distinguishing it from the 20Mbps variants within the same series.

Replacement Considerations

Pin-compatible replacements include other members of the MAX3030E–MAX3033E family, such as the MAX3031EEUE for similar 2Mbps performance. Direct equivalents to legacy parts include the 26LS31 and SN75174, though these lack the enhanced ESD protection and hot-swap features.
