MAX3041CSE+T

Overview

The MAX3041CSE+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 supply and supports data rates up to 2.5Mbps. The device features slew-rate limiting to minimize EMI and reduce reflections. Outputs are protected against ±10kV electrostatic discharge (Human Body Model) and withstand ±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 supply current is typically 1mA, with a low-power shutdown mode consuming 2nA. It is housed in a 16-pin Narrow SO package.

Feature Summary

• Integrated hot-swap capability prevents erroneous data transfer during board insertion or power-up sequences.
• Outputs feature robust protection against ±10kV electrostatic discharge and ±4kV electrical fast transients.
• Slew-rate limited drivers minimize electromagnetic interference and signal reflections on improperly terminated cables.
• Low-power shutdown mode reduces standby consumption to 2nA while maintaining high-impedance outputs.

Applications

• Telecommunications equipment
• Industrial motor control systems
• Networking infrastructure
• Industrial programmable logic controllers

Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm the package type matches the required PCB footprint. Ensure the temperature grade aligns with the operational environment requirements. Cross-reference the ordering suffix to confirm the specific packaging format intended for assembly.

Selection Notes

Select this model when a 2.5Mbps data rate is sufficient for the application. Choose this part if hot-swap functionality is required for telecom backplanes. Verify compatibility with existing receiver components such as the MAX3093E or MAX3095. Consider the narrow SO package dimensions against available board space constraints.

Part Context

This component belongs to the MAX3040–MAX3045 family of quad transmitters. It serves as a pin-compatible upgrade to industry-standard parts like the SN75174 and DS26LS31C. The family offers various speed options, with the MAX3041 specifically optimized for 2.5Mbps performance. It complements Maxim's line of differential line receivers for complete bus solutions.

Replacement Considerations

Pin-compatible replacements include the SN75174 and DS26LS31C. Other family members like the MAX3040 (250kbps) or MAX3042B (20Mbps) may be suitable depending on speed requirements. Verify that the substitute maintains the necessary ESD protection levels and hot-swap capabilities.
