MAX3086ESD+T

Overview

The MAX3086ESD+T is a high-speed RS-422/RS-485 transceiver featuring one driver and one receiver. It operates on a single +5V supply (4.75V to 5.25V) with a typical quiescent current of 375µA. The device supports full-duplex communication at data rates up to 10Mbps without slew-rate limiting. It incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The component provides a 1/8-unit-load receiver input impedance, allowing up to 256 transceivers on the bus. It is housed in a 14-pin SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Fail-safe design ensures a logic-high receiver output during idle or fault conditions
• High-speed transmission capability reaching 10Mbps without slew-rate limitations
• Supports extensive network topologies with 1/8-unit-load receiver impedance

Applications

• RS-422 and RS-485 serial communications networks
• Industrial control local area networks
• Level translation interfaces for digital systems

Procurement Notes

Verify the specific suffix 'ESD' against the manufacturer's official documentation to confirm the extended industrial temperature rating (-40°C to +85°C). Ensure the '+T' designation matches the required reel packaging format for surface-mount assembly processes. Cross-reference the pinout configuration with the standard 14-SOIC layout to prevent integration errors.

Selection Notes

Select this component for applications requiring full-duplex operation at speeds up to 10Mbps. It is suitable for environments where fail-safe behavior is critical to maintain system integrity during bus faults. Consider the 1/8-unit-load specification when calculating total node capacity for multi-drop networks exceeding standard unit load limits.

Part Context

This device belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-422 and RS-485 standards. While other members of the series offer selectable slew rates or half-duplex configurations, the MAX3086 specifically targets full-duplex applications requiring maximum speed without signal distortion from slew-rate limiting.

Replacement Considerations

The MAX3086EESA+ is a pin-compatible alternative within the same product family. Verify that the replacement maintains the required full-duplex functionality and 10Mbps data rate specifications before implementation.
