MAX483MSA/PR

Drivers, Receivers, Transceivers Overview

The MAX483MSA/PR is a low-power, half-duplex RS-485 and RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates one driver and one receiver within an 8-pin SOIC package. The device supports data transmission rates up to 250 kbps with slew-rate-limited drivers to minimize electromagnetic interference (EMI). It operates on a single +5V supply voltage, drawing only 150 µA in shutdown mode. The component features fail-safe receiver logic and is designed for industrial applications requiring reliable serial communication over long distances.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate-limited drivers reduce EMI and reflections for error-free transmission at high speeds
• Fail-safe receiver logic ensures a high output state when inputs are open or floating
• Shutdown mode significantly reduces power consumption for battery-operated systems

Drivers, Receivers, Transceivers Applications

• Industrial control networks using RS-485 multi-drop configurations
• Building automation and security systems requiring low-power communication
• Portable instrumentation and medical devices utilizing RS-422 point-to-point links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PR' against official Analog Devices documentation to confirm tape-and-reel packaging status. Ensure the part number matches the exact temperature range and RoHS compliance requirements for your manufacturing process. Cross-reference with authorized distributors to confirm current availability and authenticity of the Maxim Integrated branded component.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require robust RS-485 or RS-422 communication with minimal power consumption. The slew-rate limitation makes it suitable for noisy environments where signal integrity is critical. Compare with non-slew-rate limited variants if higher data rates above 250 kbps are required, or consider 3.3V versions if operating voltage differs from the standard 5V supply.

Drivers, Receivers, Transceivers Part Context

The MAX483 belongs to the broader MAX48x family of low-power transceivers from Maxim Integrated. This family includes variants like the MAX485 and MAX487, which share similar pinouts but differ in slew-rate characteristics and fault tolerance. The MAX483 specifically targets applications needing reduced EMI without sacrificing the reliability of standard RS-485 protocols.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include the MAX485CPE+T for non-slew-rate applications or the MAX487ESA+ for enhanced fault tolerance. Verify compatibility with existing PCB footprints and ensure electrical parameters such as drive strength and receiver sensitivity meet system requirements before substitution.
