MAX14776EATA+T

Drivers, Receivers, Transceivers Overview

The MAX14776EATA+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 500kbps with slew-rate limited outputs. The device features ±65V fault protection on driver outputs and receiver inputs, along with hot-swap protection and thermal shutdown. It includes a fail-safe receiver that guarantees a logic-high output when inputs are open or shorted. The component utilizes an 8-pin TDFN-EP package and functions 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
• Slew-rate limited outputs optimized for data rates up to 500kbps to minimize EMI
• Fail-safe receiver design ensures a logic-high output during input faults or bus idle states
• Hot-swap functionality prevents unintended driver activation during board insertion

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 component meets lead-free and RoHS compliance standards as indicated by the '+' suffix before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model specifically for applications requiring data rates up to 500kbps where slew-rate limiting is beneficial for noise reduction. Choose this part over the MAX14775E variant if high-speed transmission exceeding 500kbps is not required. Verify that the 8-pin TDFN-EP package dimensions fit the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX14775E/MAX14776E series of fault-protected transceivers. It shares the same physical package and pinout as the MAX14775E but differs in electrical performance characteristics regarding maximum data rate and output slew rate specifications.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14775EATA+T serves as a direct functional replacement for the MAX14776EATA+T, provided the application does not require data rates higher than 500kbps.
