MAX3041ESE+T

Overview

The MAX3041ESE+T 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 ±4kV Electrical Fast Transient immunity 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 Narrow SO package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap capability eliminates false transitions on the data cable during power-up or hot insertion.
• Slew-rate limited design minimizes electromagnetic interference (EMI) and reduces reflections caused by improperly terminated cables.
• Outputs protected to ±10kV using the Human Body Model and withstand ±4kV Electrical Fast Transient/Burst Stressing.
• Low-power shutdown mode consumes only 2nA, while operating supply current is 1mA.

Applications

• Telecommunications Equipment
• Industrial Motor Control
• Transmitter for ESD-Sensitive Applications
• Hand-Held Equipment
• Industrial PLCs

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required package type and temperature range. Ensure compliance with RoHS directives if applicable to your assembly process. Cross-reference the datasheet revision date to ensure all electrical characteristics align with your system requirements before finalizing procurement.

Selection Notes

Select this component when interfacing with twisted-pair balanced lines requiring robust ESD protection and low EMI emissions. It serves as a pin-compatible upgrade to industry-standard devices like the SN75174. Consider the MAX3041ESE+T for applications needing guaranteed device-to-device skew and hot-swap functionality. Pair with compatible receivers such as the MAX3093E or MAX3095 for optimal performance in RS-485/RS-422 networks.

Part Context

This part belongs to the MAX3040–MAX3045 family of 5V quad RS-485/RS-422 transmitters. The MAX3041 variant specifically targets data rates up to 2.5Mbps. It is designed for digital data transmission over twisted-pair balanced lines. The family offers space-saving packages including TSSOP, narrow SO, and wide SO options. It provides an upgrade path for legacy designs requiring enhanced transient immunity.

Replacement Considerations

The MAX3041ESE+T is pin-compatible with the 'SN75174, 'DS26LS31C, and LTC487. Verify that replacement parts support the same 2.5Mbps data rate and slew-rate limiting characteristics. Ensure the substitute component also offers ±10kV HBM ESD protection and hot-swap capability to maintain system reliability during board insertion.
