MAX3033EEUE+

Overview

The MAX3033EEUE+ 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 maximum data rate of 2Mbps and features slew-rate limiting. The device provides ±15kV ESD protection on outputs, hot-swap functionality, and thermal shutdown. It 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 transmission
• Hot-swap capability for safe insertion
• ±15kV ESD protection on driver outputs
• Low-power design with <100µA static current

Applications

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

Procurement Notes

Verify the component matches the exact part number MAX3033EEUE+. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the package type is 16-TSSOP and the temperature grade is industrial (-40°C to +85°C). Check for RoHS compliance markings as indicated by the '+' suffix.

Selection Notes

Select this component when a quad RS-422 transmitter with a guaranteed 2Mbps data rate is required. It is suitable for applications needing slew-rate control to minimize EMI. Choose this over the 20Mbps variants (MAX3030E/MAX3032E) if lower electromagnetic interference is a priority. Verify that the system requires the dual-enable pinout configuration specific to the MAX3033E.

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 specifically offers the 2Mbps baud rate variant with slew-rate limiting, distinguishing it from the higher-speed 20Mbps models in the same series.

Replacement Considerations

Public confirmed substitute part numbers include MAX3033ECUE+, MAX3033EESE, and MAX3033ECSE.
