MAX3488EESA+

Overview

The MAX3488EESA+ is a full-duplex RS-422/RS-485 transceiver from the MAX3483E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3.0V to +3.6V supply and supports data rates up to 250kbps with slew-rate-limited drivers. The device features ±15kV ESD protection (Human Body Model) and ±6kV contact discharge protection per IEC 1000-4-2. It includes fail-safe receiver inputs that guarantee a logic-high output when inputs are open. Packaged in an 8-pin SOIC, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Slew-rate-limited driver outputs minimize electromagnetic interference (EMI) and reduce signal reflections caused by improperly terminated cables.
• Integrated fail-safe receiver ensures a logic-high output state if both differential inputs are left open-circuit.
• Robust electrostatic discharge protection on all I/O pins withstands high static events without latch-up or damage.
• Driver outputs include short-circuit current limiting and thermal shutdown circuitry for overload protection.

Applications

• Telecommunications systems
• Industrial-control local area networks
• Transceivers for EMI-sensitive applications
• Integrated services digital networks
• Packet switching environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Ensure the specific suffix matches required packaging and temperature grades. Cross-reference datasheet revisions to validate electrical characteristics against design requirements.

Selection Notes

Select this part for full-duplex communication requiring low-power operation at moderate speeds. The slew-rate limitation makes it suitable for noisy environments or long cable runs where reflection management is critical. Verify compatibility with system voltage levels and interface timing constraints before integration.

Part Context

This component belongs to the MAX3483E family of 3.3V-powered transceivers. Unlike half-duplex variants such as the MAX3483E, the MAX3488E provides independent transmit and receive paths. It shares pinout compatibility with industry standards while offering enhanced ESD robustness compared to older generations.

Replacement Considerations

MAX3490EESA+ offers similar functionality but supports higher data rates up to 12Mbps. ADM3488ARZ is a comparable full-duplex alternative from Analog Devices. Verify pinout compatibility and electrical specifications before substituting.
