MAX3485EESA+T

Drivers, Receivers, Transceivers Overview

The MAX3485EESA+T is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.0V to +3.6V supply without requiring a charge pump. The device supports data rates up to 12Mbps and features ±15kV ESD protection on all I/O pins. It includes one driver and one receiver in an 8-pin NSOIC package, with an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced electrostatic discharge (ESD) protection for transmitter outputs and receiver inputs
• Low-power shutdown mode with typical 2nA standby current
• Fail-safe receiver input that guarantees a logic-high output when inputs are open
• Driver short-circuit current limiting and thermal shutdown protection

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix matches the required package type and RoHS compliance status. Ensure the supply voltage and interface requirements align with the system design specifications before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex communication applications requiring high-speed data transmission up to 12Mbps. It is suitable for designs needing robust ESD protection and low power consumption. Verify compatibility with +5V logic levels if interfacing with higher voltage systems.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3483E family of 3.3V-powered transceivers. Unlike slew-rate-limited variants designed for lower speeds, the MAX3485E provides full-speed performance while maintaining industry-standard pinouts compatible with legacy designs like the 75176.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3485ECSA+T serves as a direct replacement offering identical electrical characteristics in a different SOIC-8 variant.
