MAX3041CUE+

Overview

The MAX3041CUE+ is a quad RS-485/RS-422 transmitter manufactured by Analog Devices Inc./Maxim Integrated. 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 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. Operating current is 1mA, with a shutdown mode consuming 2nA. It is housed in a 16-pin TSSOP package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Slew-rate limited outputs for reduced electromagnetic interference
• Hot-swap capability prevents erroneous data during board insertion
• High robustness against electrostatic discharge and fast transients
• Ultra-low power consumption with dedicated shutdown mode

Applications

• Telecommunications equipment
• Industrial motor control systems
• Transmitter applications requiring ESD sensitivity
• Hand-held industrial equipment
• Industrial PLC networks

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the ordering suffix matches the required temperature range and package type. Ensure compliance with RoHS standards as indicated by the plus sign in the part number. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this model when a 2.5Mbps data rate is sufficient for the application. Choose this variant over the MAX3040 if higher speed is needed, or over the MAX3042B if lower power consumption is prioritized over maximum speed. Verify that the system requires the specific enable pin configuration associated with the MAX3041/MAX3044 family members.

Part Context

This component belongs to the MAX3040–MAX3045 family of quad RS-485/RS-422 transmitters. It serves as a low-power, ESD-protected upgrade to industry-standard parts like the SN75174 and DS26LS31C. The family offers various speed options, with the MAX3041 specifically optimized for 2.5Mbps transmission over twisted-pair balanced lines.

Replacement Considerations

Pin-compatible replacements include the 'SN75174 and 'DS26LS31C, though these lack the enhanced ESD protection and hot-swap features. Other family members such as the MAX3040 (250kbps) or MAX3042B (20Mbps) may be used if speed requirements differ.
