MAX14782EAUA+

Drivers, Receivers, Transceivers Overview

The MAX14782EAUA+ is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 500 kbps. The device features 35 kV Human Body Model (HBM) electrostatic discharge protection on the bus pins, ensuring robust performance in electrically noisy environments. It is housed in an 8-pin uMAX package, designed for surface-mount applications with a compact footprint suitable for space-constrained industrial designs.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-level ESD protection rated at 35 kV HBM on differential I/O lines
• Operates across a wide single-supply voltage range from 3 V to 5.5 V
• Provides fail-safe receiver functionality to ensure a high logic output when the bus is idle

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building automation systems
• Metering infrastructure communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AUA+' against official datasheets to confirm the 8-pin uMAX package configuration. Ensure compatibility with required operating temperature ranges and signal integrity specifications before integration into final hardware designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring moderate data speeds up to 500 kbps with enhanced noise immunity. Compare pinout and package dimensions against existing board layouts. Verify that the 35 kV ESD rating meets the environmental requirements of the target deployment site.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14782E series of robust RS-485/RS-422 transceivers. It shares functional similarities with other members of the family but differs in package type and specific electrical characteristics. It serves as a reliable interface solution for serial communication in harsh industrial settings.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other MAX14782 variants with different packages, such as MAX14782EESA+ (SOIC-8). Cross-reference pinouts and electrical parameters carefully to ensure functional equivalence without redesigning the PCB layout.
