MAX14775EATA+T

Drivers, Receivers, Transceivers Overview

The MAX14775EATA+T is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 3V to 5.5V supply and supports data rates up to 20Mbps. The device integrates ±65V fault protection on driver outputs and receiver inputs, along with hot-swap protection and thermal shutdown. It features a 1/3-unit load input impedance, allowing up to 100 devices on a bus. The component includes fail-safe logic that ensures a high receiver output when inputs are open or shorted. It is housed in an 8-pin TDFN-EP package and operates over a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±65V fault protection for robust communication in harsh industrial environments
• High-performance design supporting data rates up to 20Mbps with low-power shutdown capability
• Fail-safe receiver logic guarantees a high output state during input faults or disconnection

Drivers, Receivers, Transceivers Applications

• Industrial field bus networks
• Motion controllers
• HVAC systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '+T' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the 'A' designation aligns with the 8-pin TDFN-EP package type. Ensure the 'E' suffix indicates the extended industrial temperature range specifications are met for the target deployment environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed data transmission up to 20Mbps alongside significant overvoltage tolerance. The integrated ±65V protection eliminates the need for external clamping components, simplifying the circuit design. Consider the 8-pin TDFN-EP package for space-constrained layouts while ensuring adequate thermal management for the exposed pad.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14775E/MAX14776E series of fault-protected transceivers. It shares the same pinout and core functionality as the MAX14775EASA+T but utilizes a different surface-mount package. The series is designed to replace standard RS-485 transceivers in noisy environments where bus line faults are common.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents within the same series include the MAX14775EASA+T, which offers identical electrical characteristics in an 8-pin SOIC package.
