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 unit load input impedance allows up to 256 transceivers on the bus. It is housed in a 14-pin SO package.

Feature Summary

• Fail-safe receiver circuitry ensures a logic-high output during idle or fault conditions
• High-speed transmission capability up to 10Mbps without slew-rate limitations
• Low power consumption with 375µA typical no-load supply current
• Supports high node density with 1/8-unit-load receiver input impedance

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring high-speed data transfer

Procurement Notes

Verify the specific suffix 'ESD' against the manufacturer's ordering information to confirm the commercial temperature range (0°C to +70°C). Ensure the package type matches the required PCB footprint, as this part number corresponds to the 14-pin Small Outline package. Cross-reference the RoHS compliance status with the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select the MAX3086ESD for applications requiring full-duplex operation at speeds up to 10Mbps. This model is distinct from the MAX3080 series, which limits data rates to 115kbps via slew-rate limiting. Choose this variant when minimizing electromagnetic interference through slew-rate reduction is not a primary design constraint compared to maximum throughput requirements.

Part Context

This component belongs to the MAX3080–MAX3089 family of high-speed transceivers manufactured by Analog Devices / Maxim Integrated. The family shares common features such as fail-safe protection and low-power shutdown modes. The MAX3086 specifically differentiates itself within the group by offering unrestricted driver slew rates to support the highest data rates in the series while maintaining full-duplex functionality.

Replacement Considerations

The MAX3080E and MAX3083E are pin-compatible alternatives within the same family. However, they offer reduced data rates of 115kbps and 500kbps respectively due to internal slew-rate limiting. Verify if the application can tolerate these lower speeds before substituting.
