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) within an industrial temperature range of 0°C to +70°C. It incorporates ±15kV ESD protection, fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and allows up to 256 units on the bus. Quiescent current is typically 375µA.

Feature Summary

• Full-duplex communication architecture with independent driver and receiver paths
• Fail-safe receiver design guarantees a logic-high state during input disconnection or shorting
• Enhanced electrostatic discharge protection on all I/O pins

Applications

• RS-422 and RS-485 serial communications 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). Confirm the package type matches the required PCB footprint. Ensure the application voltage remains within the specified 4.75V to 5.25V limits for proper operation.

Selection Notes

Select this component for full-duplex applications requiring speeds up to 10Mbps. Unlike slew-rate limited variants, this model does not restrict edge rates, making it suitable for shorter cable runs where signal integrity is maintained without reflection mitigation.

Part Context

This part belongs to the MAX3080E–MAX3089E family of high-speed transceivers. It shares pin compatibility with industry-standard parts like the 75180 but includes additional features such as enhanced ESD protection and fail-safe logic. It is distinct from half-duplex models in the same series.

Replacement Considerations

Pin-compatible alternatives include the MAX3080E and MAX3083E, though these feature slew-rate limiting that reduces maximum data rates. Verify that any substitute maintains the required full-duplex configuration and operating temperature range.
