MAX3041EUE+T

Overview

The MAX3041EUE+T is a quad RS-485/RS-422 transmitter designed for digital data transmission over twisted-pair balanced lines. It operates from a single +5V power supply and supports data rates up to 2.5Mbps. The device features slew-rate limiting to minimize electromagnetic interference (EMI) and reduce reflections caused by improperly terminated cables. All outputs are protected against ±10kV electrostatic discharge (ESD) using the Human Body Model and withstand ±4kV Electrical Fast Transient/Burst stress per IEC 1000-4-4. It includes hot-swap capability to eliminate false transitions during power-up or insertion. The component consumes 1mA of operating supply current and enters a low-power shutdown mode with 2nA consumption.

Feature Summary

• Slew-rate limited outputs at 2.5Mbps to minimize EMI and cable reflections
• Hot-swap capability prevents erroneous data transfer during board insertion
• Robust protection against ±10kV ESD and ±4kV fast transient bursts
• Low-power operation with 1mA active current and 2nA shutdown current

Applications

• Telecommunications equipment
• Industrial motor control systems
• Transmitter applications requiring ESD sensitivity
• Hand-held industrial equipment
• Industrial PLCs and networking devices

Procurement Notes

Verify the specific ordering suffix to confirm package type, temperature range, and lead-free status. Confirm that the '+T' designation indicates tape-and-reel packaging. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Selection Notes

Select this component when a quad transmitter with 2.5Mbps speed and slew-rate limiting is required. It serves as a pin-compatible upgrade to industry-standard parts like the SN75174 and DS26LS31C. Consider the TSSOP package for space-constrained designs compared to SO packages.

Part Context

This part belongs to the MAX3040–MAX3045 family of 5V quad transmitters. While other members support 250kbps or 20Mbps, the MAX3041 specifically targets the 2.5Mbps tier. It is designed to pair optimally with MAX3093E/MAX3095 receivers.

Replacement Considerations

Public confirmed substitutes include SN75174, DS26LS31C, and LTC487 due to pin compatibility.
