MAX3080ECPD

Overview

The MAX3080ECPD is a high-speed RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver in a single package. The device supports data rates up to 115kbps with slew-rate-limited drivers to minimize electromagnetic interference. It operates on a single 5V supply, typically drawing 375µA of supply current. The component features fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It provides ±15kV ESD protection on the bus pins and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe design ensures a logic-high receiver state during bus idle or fault conditions
• Slew-rate-limited drivers reduce signal reflections and electromagnetic emissions
• Integrated electrostatic discharge protection rated at ±15kV for robust operation

Applications

• RS-422 and RS-485 communication networks
• Industrial control systems requiring noise immunity
• EMI-sensitive applications utilizing controlled slew rates

Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and temperature grade. Ensure compatibility with system voltage levels and interface requirements before integration. Cross-reference manufacturer part numbers to avoid counterfeit components.

Selection Notes

Select this component for applications requiring full-duplex communication with moderate data speeds. The integrated fail-safe feature simplifies bus management in multi-drop configurations. Consider thermal dissipation limits when operating near maximum temperature boundaries.

Part Context

This part belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485 and RS-422 standards. The family offers various slew-rate options and unit-load capabilities to suit different network topologies and speed requirements across industrial environments.

Replacement Considerations

Direct substitutes include other members of the MAX308x series such as the MAX3081 or MAX3082, provided they match the required package and electrical specifications. Verify pinout compatibility and functional equivalence before substitution.
