MAX3086ECSD+T

Overview

The MAX3086ECSD+T is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply (4.75V to 5.25V) and supports data rates up to 10Mbps with unrestricted driver slew rates. The device features ±15kV ESD protection, fail-safe receiver circuitry guaranteeing a logic-high output when inputs are open or shorted, and low quiescent current of 375µA. Packaged in a 14-pin SOIC, it allows up to 256 units on the bus.

Feature Summary

• Full-duplex communication architecture with independent driver and receiver channels
• Fail-safe receiver design ensuring high output state during idle or fault conditions
• Enhanced electrostatic discharge protection on all I/O pins

Applications

• RS-422 and RS-485 serial communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring high-speed differential signaling

Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required temperature range and packaging format. Cross-reference manufacturer part numbers to avoid counterfeit components.

Selection Notes

Select this model for full-duplex applications requiring 10Mbps transmission speeds without slew-rate limitations. Compare against MAX3080E or MAX3083E if lower data rates or half-duplex configurations are sufficient for the system requirements.

Part Context

This component belongs to the MAX3080E–MAX3089E family of high-speed transceivers. It shares the same package and basic interface standards as other members but is specifically optimized for full-duplex operation at maximum speed within the series.

Replacement Considerations

Pin-compatible alternatives include the MAX3080E and MAX3083E. Verify that the replacement supports the required duplex mode and data rate before implementation.

FAQ

What is the fail-safe behavior of the MAX3086ECSD+T?

The receiver guarantees a logic-high output when the A and B inputs are open, shorted, or connected to a terminated line with all drivers disabled.

How does the MAX3086ECSD+T handle ESD events?

All transmitter outputs and receiver inputs are protected to ±15kV using the Human Body Model.

Is the MAX3086ECSD+T compatible with industry-standard pinouts?

Yes, it is pin-compatible with the industry-standard 75180 device.
