MAX3082EESA-C2S

Overview

The MAX3082EESA-C2S is a half-duplex RS-485 and RS-422 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a single 5V supply voltage and supports data transmission rates up to 10 Mbps. The device integrates one driver and one receiver within an SOIC-8 surface-mount package. Key electrical characteristics include 15 kV electrostatic discharge (ESD) protection on all bus pins and fail-safe functionality that ensures a high logic state at the receiver output when the inputs are open or floating.

Feature Summary

• High-speed data transmission capability up to 10 Mbps with slew-rate limiting to minimize electromagnetic interference (EMI).
• Robust 15 kV ESD protection on all bus terminals, enhancing reliability in electrically noisy industrial environments.
• Fail-safe receiver design guarantees a defined high logic level at the output if differential inputs are disconnected.
• Half-duplex operation allows bidirectional communication over a single differential pair using a single 5V power supply.

Applications

• Industrial automation systems requiring robust serial communication over long distances.
• Building automation networks utilizing RS-485 multi-drop configurations.
• Metering applications such as electricity, gas, and water meters needing reliable data telemetry.
• Security and access control systems involving multiple peripheral devices.

Procurement Notes

Verify the specific suffix 'C2S' against official Analog Devices documentation to confirm temperature range and packaging specifications. Ensure compatibility with existing board layouts for the SOIC-8 package. Confirm RoHS compliance status through current manufacturer datasheets before finalizing procurement plans.

Selection Notes

Select this component for designs requiring high-speed RS-485/RS-422 communication with integrated ESD protection. The 5V supply requirement suits legacy systems or those without dedicated 3.3V rails for interface logic. Consider the fail-safe feature for applications where bus line integrity must be monitored during idle states or disconnection events.

Part Context

This part belongs to the MAX308x family of low-power, half-duplex transceivers. It shares functional similarities with the MAX3080 and MAX3081 but offers higher speed capabilities. The device is designed to replace older discrete solutions, providing a compact footprint and enhanced noise immunity for standard serial communication protocols.

Replacement Considerations

Direct pin-compatible alternatives include the MAX3082EESA+ and MAX3082EESA-T. Verify that substitute parts match the required operating temperature range and package dimensions. Check for any differences in ESD protection levels or drive strength when evaluating cross-brand replacements.
