MAX3041EWE+

Overview

The MAX3041EWE+ is a quad RS-485/RS-422 transmitter manufactured by Maxim Integrated (Analog Devices). It operates from a single +5V supply and supports data rates up to 2.5Mbps with slew-rate limiting to minimize EMI. The device features ±10kV Human Body Model ESD protection on all outputs and withstands ±4kV Electrical Fast Transient/Burst stress per IEC 1000-4-4. It includes hot-swap capability to prevent false transitions during power-up or insertion. The part is housed in a 16-pin Wide SO package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap capability prevents erroneous data transfer during board insertion or power-up sequences.
• Slew-rate limited output drivers reduce signal reflections and electromagnetic interference.
• Integrated high-level electrostatic discharge protection ensures robustness against transient events.

Applications

• Telecommunications equipment
• Industrial motor control systems
• Hand-held equipment interfaces
• Industrial PLC networks

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the required Wide SO package and extended temperature specifications. Ensure compliance with RoHS directives if applicable to the specific procurement batch.

Selection Notes

Select this model for applications requiring reliable communication over twisted-pair balanced lines at speeds up to 2.5Mbps. It serves as a low-power upgrade to industry-standard parts like the SN75174. Ensure system design accommodates the 1mA operating current and utilizes appropriate termination resistors to match cable impedance.

Part Context

This component belongs to the MAX3040–MAX3045 family of quad transmitters designed for digital data transmission. It offers pin-compatible alternatives to legacy standards, providing enhanced ESD immunity and lower power consumption while maintaining compatibility with standard RS-485 and RS-422 receiver families.

Replacement Considerations

The MAX3041EWE+ is pin-compatible with the 'SN75174 and 'DS26LS31C. Direct replacements include other members of the MAX304x family such as the MAX3040 or MAX3042B, provided the data rate requirements align with the specific application needs.
