MAX3083ECSD+

Overview

The MAX3083ECSD+ is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 500kbps with slew-rate-limited drivers. The device features ±15kV ESD protection on all I/O pins and fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. It utilizes a 14-pin SOIC package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output during bus idle states, input shorts, or open circuits.
• Slew-rate limiting minimizes electromagnetic interference (EMI) and reduces signal reflections on improperly terminated cables.
• Enhanced electrostatic discharge (ESD) protection rated at ±15kV via the Human Body Model for robust industrial operation.

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• Level translation applications

Procurement Notes

Verify the specific suffix 'CSD+' against official documentation to confirm the 14-pin SOIC package and commercial temperature range. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement orders.

Selection Notes

Select this component for full-duplex applications requiring moderate speeds up to 500kbps. It is suitable where EMI reduction is critical due to its slew-rate-limited driver characteristics. Verify that the system operates within the specified +5V supply voltage constraints.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. While sharing core architecture with other variants like the MAX3086E, it is specifically configured for half-duplex or full-duplex modes with defined slew-rate limits distinct from the uncontrolled high-speed models in the series.

Replacement Considerations

The datasheet notes pin compatibility with industry-standard parts such as the 75180. Engineers should verify electrical parameter alignment and pinout definitions before substituting legacy components.
