MAX1490EACPG

Drivers, Receivers, Transceivers Overview

The MAX1490EACPG is a complete, electrically isolated RS-485/RS-422 data interface IC manufactured by Analog Devices Inc./Maxim Integrated. It integrates transceivers, optocouplers, and a transformer to provide galvanic isolation in a standard 24-pin DIP package. The device operates on a single +5V supply on the logic side, powering both sides of the interface. Key electrical characteristics include ±15kV ESD protection, a data rate up to 250kbps, and an isolation voltage of 1260VRMS for one minute. It features slew-rate limited drivers to reduce electromagnetic interference and signal reflections.

Drivers, Receivers, Transceivers Feature Summary

• Provides complete electrical isolation between logic and bus sides using integrated optocouplers and transformers.
• Features slew-rate limited drivers to minimize electromagnetic interference and signal reflections in noisy environments.
• Includes robust fault protection mechanisms such as short-circuit current limiting and thermal shutdown.
• Offers high electrostatic discharge (ESD) protection rated at ±15kV on input and output lines.

Drivers, Receivers, Transceivers Applications

• Medical equipment requiring strict electrical isolation standards.
• Telecommunications infrastructure with high noise immunity needs.
• Building control networks operating in electrically harsh environments.

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status and specific revision markings against official datasheets before integration. Check for obsolescence notices as this series may have been superseded by newer variants. Ensure proper handling procedures are followed for the DIP package during assembly.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full duplex communication with galvanic isolation is required for RS-485 or RS-422 protocols. It is suitable for applications needing ±15kV ESD protection and operation within commercial temperature ranges. Consider alternative packages if surface-mount technology is preferred over through-hole DIP configurations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1490 family of isolated data interfaces designed for reliable communication in industrial settings. It serves as a bridge between microcontroller systems and field buses, ensuring signal integrity across isolation barriers. The device simplifies design by integrating passive isolation components directly into the semiconductor package.
