MAX3086ECSD+

Overview

The MAX3086ECSD+ 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 includes ±15kV ESD protection, fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and thermal shutdown. The component is housed in a 14-pin SOIC package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Full-duplex communication architecture with independent driver and receiver channels
• High-speed transmission capability up to 10Mbps without slew-rate limitations
• Integrated fail-safe mechanism that guarantees a logic-high receiver output during bus idle states

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 specific suffix 'C' indicates the commercial temperature range (0°C to +70°C), distinct from the industrial grade (-40°C to +85°C). Confirm the 'SD+' designation corresponds to the 14-pin SOIC plastic package. Ensure compatibility with standard +5V logic levels before integration into existing system designs.

Selection Notes

Select this model for full-duplex applications requiring maximum throughput up to 10Mbps. Unlike the MAX3080E series which limits slew rates for lower speeds, the MAX3086E provides unrestricted drive speeds. Verify that the system environment remains within the commercial temperature limits defined by the 'C' suffix rather than the extended industrial range.

Part Context

This component belongs to the MAX3080E–MAX3089E family of high-speed transceivers. It shares pinout compatibility with industry-standard parts like the 75180 but offers enhanced ESD protection and fail-safe features. The MAX3086E specifically addresses the need for unthrottled data rates in full-duplex configurations compared to the slew-rate-limited variants in the same series.

Replacement Considerations

The MAX3086EESD+ serves as the direct industrial-grade replacement, offering identical electrical characteristics but extending the operating temperature range to -40°C to +85°C.
