MAX3041CUE+T

Overview

The MAX3041CUE+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. The device features ±10kV ESD protection (Human Body Model) 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. The component is housed in a 16-pin TSSOP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Hot-swap capability eliminates false transitions on the data cable during power-up or hot insertion
• Slew-rate limiting minimizes electromagnetic interference and reduces reflections caused by improperly terminated cables
• Outputs protected to ±10kV using the Human Body Model and withstand ±4kV per IEC 1000-4-4 Electrical Fast Transient/Burst Stressing

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact temperature range and package variant. Ensure compatibility with system voltage requirements and interface standards before integration. Cross-reference manufacturer datasheets for accurate pin configurations and electrical characteristics.

Selection Notes

Select this component when designing systems requiring quad differential transmission over twisted-pair balanced lines at speeds up to 2.5Mbps. It serves as a low-power, ESD-protected upgrade to industry-standard drivers like the SN75174. Consider its slew-rate limited performance for applications where minimizing EMI and signal reflections is critical.

Part Context

This part belongs to the MAX3040–MAX3045 family of 5V quad RS-485/RS-422 transmitters. The MAX3041 variant specifically provides a guaranteed data rate of 2.5Mbps with slew-rate limiting. It is designed for digital data transmission over twisted-pair balanced lines and offers optimum performance when paired with compatible line receivers.

Replacement Considerations

The MAX3041CUE+T is pin-compatible with the 'SN75174, 'DS26LS31C, and LTC487. When substituting these legacy components, verify that the system can accommodate the updated ESD protection levels and hot-swap functionality provided by the MAX3041.
