MAX3483CSA+T

Drivers, Receivers, Transceivers Overview

The MAX3483CSA+T is a low-power, half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. It operates from a single 3.0V to 3.6V supply and contains one driver and one receiver. The device features slew-rate-limited drivers that minimize electromagnetic interference (EMI) and reduce reflections on improperly terminated cables, supporting error-free data transmission up to 250kbps. It includes enhanced electrostatic discharge (ESD) protection of ±15kV on all I/O pins. The component utilizes an industry-standard 75176 pinout and incorporates current-limiting and thermal shutdown circuitry for driver overload protection.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers minimize EMI and reduce cable reflections for error-free data transmission
• Enhanced ±15kV ESD protection on all transmitter outputs and receiver inputs
• Low-power shutdown mode with typically 2nA supply current consumption
• Driver overload protection via short-circuit current limiting and thermal shutdown

Drivers, Receivers, Transceivers Applications

• Telecommunications systems
• Industrial-control local area networks
• Transceivers for EMI-sensitive applications
• Low-power RS-485/RS-422 communication interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CSA' corresponds to the SOIC-8 package and the commercial temperature range of 0°C to +70°C. Confirm the '+' indicates RoHS compliance status. Ensure the datasheet revision matches the required specifications for your design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this part when designing half-duplex RS-485 or RS-422 networks requiring reduced electromagnetic emissions. The MAX3483 is suitable for applications where data rates do not exceed 250kbps but require robust ESD protection and low power consumption in shutdown mode compared to faster variants.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX3483/MAX3485/MAX3486/MAX3488/MAX3490/MAX3491 family of 3.3V-powered transceivers. While other members of the series offer higher speeds up to 10Mbps or full-duplex operation, the MAX3483 specifically provides slew-rate limiting optimized for lower-speed, noise-sensitive environments.

Drivers, Receivers, Transceivers Replacement Considerations

MAX3483ESA+T offers the same electrical characteristics in an industrial temperature range (-40°C to +85°C). MAX3483CPA+ provides identical functionality in a Plastic DIP package.
