MAX3086CSD

Overview

The MAX3086CSD is a full-duplex RS-485/RS-422 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 devices on the bus. It is housed in a 14-pin SOIC package and functions within an operating temperature range of 0°C to +70°C.

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
• Supports high-density networks with 1/8-unit-load receiver input impedance

Applications

• RS-422/RS-485 communications
• Industrial-control local area networks
• Level translators

Procurement Notes

Verify the specific suffix 'CSD' corresponds to the commercial temperature range (0°C to +70°C) and 14-pin SOIC package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering part number matches the exact functional requirements for full-duplex operation at 10Mbps.

Selection Notes

Select this component for applications requiring full-duplex communication at speeds up to 10Mbps. It is suitable for environments where standard RS-485 noise immunity is required via fail-safe thresholds. Consider thermal shutdown protection features for high-power dissipation scenarios. Verify that the 14-pin package fits the available PCB footprint constraints.

Part Context

This device belongs to the MAX3080–MAX3089 family of high-speed transceivers designed for RS-485/RS-422 standards. Unlike lower-speed variants in the series, the MAX3086 offers unrestricted driver slew rates to support higher data throughput. It shares the same pinout as industry-standard parts like the 75180 but includes enhanced features such as low quiescent current and specific fail-safe characteristics defined by the Maxim Integrated product line.

Replacement Considerations

The datasheet notes pin-compatibility with the 75180. Designers should verify that any substitute maintains the 1/8-unit-load input impedance and fail-safe threshold specifications to ensure network integrity.
