MAX3485ECSA+T

Drivers, Receivers, Transceivers Overview

The MAX3485ECSA+T is a half-duplex RS-485/RS-422 transceiver operating from a single +3.3V supply without requiring a charge pump. It supports data rates up to 12Mbps and features ±15kV ESD protection on all I/O pins. The device includes one driver and one receiver with fail-safe logic that guarantees a high-level output when inputs are open. It operates within a temperature range of 0°C to +70°C in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Operates from a single +3.3V power supply
• Provides ±15kV ESD protection for RS-485 I/O pins
• Includes fail-safe receiver logic for open-circuit inputs
• Features current-limiting and thermal shutdown for driver overload protection

Drivers, Receivers, Transceivers Applications

• Telecommunications systems
• Industrial-control local area networks
• Integrated services digital networks (ISDN)
• Packet switching applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range and 'SA' denotes the SOIC package. Confirm the '+T' designation corresponds to tape-and-reel packaging as specified in the manufacturer's ordering information. Ensure compatibility with standard 8-pin SO footprints during integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for half-duplex RS-485 or RS-422 communication links requiring 12Mbps speeds. It is suitable for designs needing robust ESD protection and low-power operation at 3.3V. Verify that the 0°C to +70°C operating range meets environmental requirements, as extended temperature variants use different suffixes.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX3483E family of low-power transceivers designed for multipoint bus transmission lines. It shares pinouts with industry-standard devices like the 75176 but offers enhanced electrostatic discharge protection and optimized performance for 3.3V logic systems.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other MAX3485E variants such as MAX3485EEPA+ for plastic DIP packages or MAX3485EESA+ for extended temperature ranges. Cross-reference pinouts and electrical characteristics to ensure functional equivalence.
