MAX14776EASA+T

Drivers, Receivers, Transceivers Overview

The MAX14776EASA+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, ensuring robust communication in harsh industrial environments. It includes a fail-safe feature that guarantees a logic-high receiver output when inputs are open or shorted. The component is housed in an 8-pin SOIC package and operates within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±65V fault protection for overvoltage signal faults on communication bus lines
• Fail-safe receiver ensures logic-high output when inputs are open or shorted
• Hot-swap protection safeguards against unwanted driver activation during board insertion
• Thermal shutdown protection disables outputs when junction temperature exceeds limits

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 tape and reel packaging as documented in the official Maxim Integrated datasheet. Confirm the 'A' suffix indicates the 8-pin SOIC package variant. Ensure compliance requirements match the '+' designation for lead-free/RoHS status before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing RS-485/RS-422 interfaces requiring high noise immunity and protection against severe voltage faults up to ±65V. The MAX14776E is appropriate for applications where data rates do not exceed 500kbps, distinguishing it from the higher-speed MAX14775E. Consider the 8-pin SOIC package constraints regarding thermal dissipation and board space availability.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14775E/MAX14776E series of fault-protected transceivers. While functionally similar to the MAX14775E, the MAX14776E is specifically optimized for lower data rates up to 500kbps with slew-rate limiting to reduce electromagnetic interference. Both share identical pinouts, protection features, and package options.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14775EASA+T serves as a direct functional substitute if higher data rates up to 20Mbps are acceptable. Other MAX1477x series variants may require verification of fault protection levels and data rate compatibility.
