MAX3086CSD+T

Overview

The MAX3086CSD+T is a high-speed RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and features one driver and one receiver in a 14-pin SOIC package. The device supports data rates up to 10Mbps with unrestricted slew rates. It incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The quiescent supply current is typically 375µA, and the receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus.

Feature Summary

• Fail-safe circuitry ensures a logic-high receiver output during idle or fault conditions
• High-speed operation supporting data transmission up to 10Mbps
• 1/8-unit-load receiver input impedance enables connection of up to 256 devices on the bus

Applications

• RS-422/RS-485 communications
• Level translators
• Transceivers for EMI-sensitive applications
• Industrial-control local area networks

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required temperature range and packaging format. Ensure compliance with RoHS directives as indicated in the product specifications before integration into production systems.

Selection Notes

Select this component for full-duplex RS-485/RS-422 applications requiring high-speed data transmission without slew-rate limitations. It is suitable for environments where fail-safe behavior is critical during bus idle states. Consider the 14-pin SOIC package constraints and thermal dissipation requirements for the specific PCB layout design.

Part Context

This device belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 communication. The family includes variants with different slew-rate limits and duplex modes. The MAX3086 specifically provides full-duplex operation with unrestricted driver slew rates for maximum speed performance.

Replacement Considerations

Pin-compatible alternatives within the same family include the MAX3080 and MAX3083, though these feature reduced slew rates limiting their maximum data rate to 115kbps and 500kbps respectively. Verify functional compatibility regarding data rate requirements and duplex mode configuration.
