MAX3033EESE+T

Overview

The MAX3033EESE+T is a quad RS-422 transmitter manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +3V to +3.6V, with a typical operating voltage of +3.3V. The device supports 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. The unit consumes less than 100µA in static conditions and operates across an extended temperature range from -40°C to +85°C. It is housed in a 16-pin Narrow SO package.

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 all outputs
• Low-power design suitable for battery-operated systems

Applications

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

Procurement Notes

Verify the component against official datasheet specifications to ensure authenticity. Confirm that the part number matches the exact suffix requirements for the desired package and temperature range. Check for RoHS compliance documentation as indicated in manufacturer records. Ensure the supplier provides traceability information consistent with Analog Devices standards.

Selection Notes

Select this model when a 2Mbps baud rate with controlled slew rates is required to limit signal reflections. Choose this variant over the 20Mbps versions if minimizing electromagnetic interference is a priority. Verify that the 16-pin Narrow SO package fits the board layout constraints. Ensure the application requires only transmitter functionality without integrated receivers.

Part Context

This component 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 family offers pin-compatible options with varying data rates and enable configurations to suit different system architectures.

Replacement Considerations

The MAX3031EESE+T is a compatible alternative within the same family, offering identical pinout and functionality but with a guaranteed 20Mbps data rate instead of the 2Mbps slew-rate-limited performance.
