MAX3488EESA+T

Overview

The MAX3488EESA+T is a full-duplex transceiver for RS-422 and RS-485 communications, manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +3.6V supply with a typical current of 1.1mA. The device supports data rates up to 250kbps using slew-rate-limited drivers to minimize EMI. It features ±15kV ESD protection on all I/O pins and includes thermal shutdown and short-circuit current limiting. The component is housed in an 8-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Full-duplex communication capability with independent driver and receiver channels
• Slew-rate-limited drivers designed to reduce electromagnetic interference and signal reflections
• Robust electrostatic discharge protection rated at ±15kV across multiple testing standards
• Integrated thermal shutdown and current limiting mechanisms for driver overload protection

Applications

• Telecommunications systems requiring reliable serial data transmission
• Industrial-control local area networks operating in electrically noisy environments
• Transceivers specifically designated for EMI-sensitive applications
• Integrated Services Digital Networks (ISDN) interfaces

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and RoHS compliance status. Confirm that the 'T' designation corresponds to the intended reel packaging format rather than tube packaging. Cross-reference the part number with the latest datasheet revision to ensure compatibility with current manufacturing specifications and regional regulatory requirements.

Selection Notes

Select this component when full-duplex operation is required alongside low electromagnetic interference characteristics. The MAX3488EESA+T is suitable for designs needing robust ESD protection without external components. Ensure the application voltage remains within the specified 3.0V to 3.6V range. Consider the 250kbps data rate limit when designing high-speed communication links.

Part Context

This device belongs to the MAX3483E family of 3.3V-powered transceivers. Unlike half-duplex variants such as the MAX3483E or MAX3485E, the MAX3488E provides simultaneous two-way communication. It shares the industry-standard pinout configuration with other members of the series, facilitating design flexibility across different duplexing requirements within the same product line.

Replacement Considerations

The MAX3490E serves as a functional alternative offering higher speed capabilities. Designers must account for differences in driver slew rates and propagation delays when substituting parts. Verify pin compatibility and electrical parameter alignment before implementing any cross-model replacements in existing circuit layouts.
