MAX3041EUE+

Overview

The MAX3041EUE+ 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 IEC 1000-4-4 Electrical Fast Transient immunity. It includes hot-swap capability for safe insertion into live backplanes. The component is housed in a 16-pin TSSOP package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Hot-swap capability prevents false transitions during power-up or board insertion
• Slew-rate limited outputs reduce reflections on improperly terminated cables
• Robust transient immunity including ±10kV HBM ESD and ±4kV IEC fast transients

Applications

• Telecommunications equipment
• Industrial motor control systems
• Hand-held equipment
• Industrial PLCs
• Networking applications

Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range of -40°C to +85°C, as opposed to the 'C' suffix which covers 0°C to +70°C. Confirm the 'UE' suffix corresponds to the 16-pin TSSOP package type required for the design. Ensure compliance with RoHS standards indicated by the '+' symbol in the part number.

Selection Notes

Select this model when a 2.5Mbps data rate is required alongside slew-rate limiting to manage signal integrity on long or unterminated lines. It serves as a pin-compatible upgrade to industry-standard parts like the SN75174. Consider the MAX3040 if a lower 250kbps rate suffices, or the MAX3042B for speeds up to 20Mbps without slew-rate limiting.

Part Context

This component belongs to the MAX3040–MAX3045 family of 5V quad RS-485/RS-422 transmitters. The family offers various speed grades and enable configurations. The MAX3041 specifically targets the 2.5Mbps tier with controlled edge rates, distinguishing it from the faster MAX3042B/MAX3045B and the slower MAX3040/MAX3043 models.

Replacement Considerations

Public confirmed substitutes include the MAX3041CUE (commercial temperature) and other variants within the MAX3040-MAX3045 family that share the same pinout and functionality but differ in speed or temperature rating.
