MAX3084ECSA+T

Overview

The MAX3084ECSA+T is a half-duplex RS-485/RS-422 transceiver from the MAX3080E–MAX3089E family. It operates on a single +5V supply (4.75V to 5.25V) and supports data rates up to 500kbps with slew-rate limiting enabled via the SRL pin. The device features ±15kV ESD protection, fail-safe circuitry ensuring a logic-high receiver output when inputs are open or shorted, and low quiescent current of 375µA typical. It is housed in an 8-pin SO package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Fail-safe receiver guarantees a logic-high output when inputs are open or shorted
• Slew-rate-limited driver minimizes electromagnetic interference and reflections
• Enhanced ±15kV electrostatic discharge protection on all I/O pins
• Low-power shutdown mode reduces supply current significantly

Applications

• RS-422 and RS-485 communication networks
• Industrial control local area networks
• EMI-sensitive applications requiring controlled signal transitions

Procurement Notes

Verify the component against official Analog Devices documentation to confirm the specific suffix matches the required operational parameters. Ensure the ordering information aligns with the intended application requirements before procurement.

Selection Notes

Select this model for half-duplex applications requiring 500kbps transmission speeds. Verify that the operating environment falls within the specified commercial temperature range and voltage constraints.

Part Context

This component belongs to the MAX3080E–MAX3089E series of high-speed transceivers. It shares pin compatibility with industry-standard parts like the 75180 but includes enhanced features such as improved ESD protection and configurable slew rates.

Replacement Considerations

Pin-compatible alternatives include the 75180. Verify functional equivalence regarding slew rate limits and duplex operation before substitution.
