MAX14780EESA+

Drivers, Receivers, Transceivers Overview

The MAX14780EESA+ is a half-duplex RS-422/RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5.0V supply and features one driver and one receiver in an 8-pin SOIC package. The device supports data rates up to 500 kb/s with controlled slew rates to minimize electromagnetic interference. It provides ±30 kV ESD protection and includes fail-safe circuitry that ensures a high logic level output when inputs are open or shorted. The unit load input impedance allows for up to 256 nodes on the bus, with a typical operating current of 1.8 mA.

Drivers, Receivers, Transceivers Feature Summary

• Integrated fail-safe mechanism maintains a high logic state during input disconnection or shorting conditions
• Hot-swap capability prevents transient faults on the bus during power-up or insertion events
• Controlled slew rate driving reduces electromagnetic emissions and signal reflections
• High input impedance architecture enables extensive node density on standard communication buses

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Utility metering systems
• Solar monitoring infrastructure

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact packaging and environmental compliance status. Confirm availability through authorized distribution channels as stock levels fluctuate. Ensure the component matches the required RoHS directives for your target market. Cross-reference the datasheet revision date to validate technical specifications before integration into production designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust noise immunity and high node density on RS-485 networks. The controlled slew rate makes it suitable for environments sensitive to electromagnetic interference. Verify that the system voltage aligns with the specified +5.0V requirement. Consider the thermal performance within the industrial temperature range if operating near limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14780 series of robust interface transceivers designed for harsh industrial environments. It shares functional similarities with other Maxim integrated RS-485 devices but distinguishes itself through specific ESD ratings and node capacity features. The series focuses on reliability and ease of integration into existing communication architectures.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14780EESA+T serves as a tape-and-reel alternative offering identical electrical characteristics. Verify pin compatibility and package dimensions when substituting between tube and reel formats. Ensure the replacement variant meets the same environmental and regulatory standards.
