MAX14786EAUD+

Drivers, Receivers, Transceivers Overview

The MAX14786EAUD+ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a TSSOP-14 package. It supports data rates up to 10 Mbps and operates within a supply voltage range of 3 V to 5.5 V. The device features ±35 V fault protection on the bus lines and provides 30 kV ESD protection per IEC 61000-4-2 standards. It functions reliably across an industrial temperature range of -40°C to +85°C with a quiescent current of 1.8 mA.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±35 V fault protection for robust operation during bus line errors
• High electrostatic discharge immunity meeting IEC 61000-4-2 Level 4 standards
• Fail-safe receiver design ensures a high logic state when the bus is idle

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Modbus RTU communication links

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix EAUD against official datasheets to confirm the TSSOP-14 package and lead-free status. Confirm RoHS compliance through manufacturer documentation before integration. Ensure the component matches the exact part number to avoid pinout or electrical specification mismatches in existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring moderate speed and high noise immunity without extreme temperature requirements. It serves as a reliable alternative to higher-speed variants when cost and power efficiency are prioritized over maximum throughput. Verify that the system's bus topology aligns with its half-duplex capability.

Drivers, Receivers, Transceivers Part Context

This transceiver belongs to the MAX1478x family of robust RS-485/RS-422 interface devices. It shares core architectural similarities with other members like the MAX14780 but offers distinct packaging and performance trade-offs tailored for space-constrained industrial environments.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MAX14780EESA+ for SOIC-8 compatibility or the MAX14783 series for higher speed requirements. Cross-check pin configurations and thermal characteristics before swapping to ensure mechanical fit and electrical continuity.
