MAX14775EATA+

Drivers, Receivers, Transceivers Overview

The MAX14775EATA+ 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 features ±65V fault protection on driver outputs and receiver inputs, along with a 1/3-unit load input impedance allowing up to 100 devices on the bus. It includes fail-safe circuitry, thermal shutdown, and hot-swap protection. The component is housed in an 8-pin TDFN-EP package (3mm x 3mm) and operates within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±65V overvoltage fault protection for robust communication in harsh industrial environments
• High-speed data transmission capability up to 20Mbps with low-power shutdown mode
• Fail-safe receiver design ensures logic-high output when inputs are open or shorted
• Hot-swap functionality prevents data errors during board insertion into powered backplanes

Drivers, Receivers, Transceivers Applications

• Industrial Field Bus Networks
• Motion Controllers
• HVAC Systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '+T' indicates tape and reel packaging configuration. Confirm the 'A' suffix corresponds to the 8-pin TDFN-EP package variant. Ensure compliance requirements match the lead-free/RoHS-compliant status indicated by the '+' symbol. Cross-reference the manufacturer part number with official Analog Devices documentation to validate availability and revision history before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed RS-485 communication up to 20Mbps alongside significant overvoltage tolerance. The 1/3-unit load characteristic allows for higher node density compared to standard 1/8-unit load devices. Consider the thermal performance of the TDFN-EP package for power dissipation calculations at maximum data rates and duty cycles.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX14775E/MAX14776E series of fault-protected transceivers. The MAX14775E variant specifically targets high-speed applications, whereas the MAX14776E offers slew-rate limiting for lower data rates up to 500kbps. Both share identical pinouts and protection features, differing primarily in their switching electrical characteristics.

Drivers, Receivers, Transceivers Replacement Considerations

MAX14776EATA+ serves as a functional alternative for designs prioritizing lower data rates up to 500kbps with slew-rate limited outputs. Other compatible options include the MAX14775EASA+ for SOIC packaging requirements.
