MAX3086ESD+

Overview

The MAX3086ESD+ is a full-duplex RS-422/RS-485 transceiver featuring one driver and one receiver. It supports data rates up to 10Mbps with unrestricted slew rates. The device operates on a single +5V supply (4.75V to 5.25V) and draws 375µA typical quiescent current. It incorporates fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. The receiver input impedance is 1/8-unit-load, allowing up to 256 transceivers on the bus. It is housed in a 14-pin SO package.

Feature Summary

• Fail-safe circuitry ensures a logic-high receiver output during idle or fault conditions
• High-speed transmission capability up to 10Mbps without slew-rate limiting
• Low power consumption with 375µA typical quiescent supply current
• 1/8-unit-load receiver input impedance supporting high node counts

Applications

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

Procurement Notes

Verify the specific suffix 'ESD+' against official documentation to confirm the operating temperature range of -40°C to +85°C. Ensure the package type matches the required 14-SO footprint. Confirm RoHS compliance status through the manufacturer's latest ordering information before finalizing procurement specifications.

Selection Notes

Select this component for full-duplex applications requiring high-speed data transmission up to 10Mbps. It is suitable for systems needing fail-safe protection and low standby power. Consider alternative models like the MAX3080 if reduced slew rates are necessary for lower data speeds to minimize EMI.

Part Context

This device belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 communication. The family shares common features such as fail-safe operation and low power consumption, but varies in duplex mode and slew-rate limitations. The MAX3086 specifically provides full-duplex operation with unrestricted slew rates.

Replacement Considerations

The MAX3086CSD+ is a pin-compatible alternative within the same series, differing primarily in the guaranteed operating temperature range.
