MAX14783EAUA+T

Drivers, Receivers, Transceivers Overview

The MAX14783EAUA+T is a half-duplex RS-485 transceiver in an 8-pin µMAX package. It operates on a 3.0V to 5.5V supply with a maximum data rate of 42Mbps at 3.0V to 3.6V, and 6Mbps at 3.0V to 5.5V. The device provides ±35kV HBM ESD protection and supports -40°C to +125°C operation. Key electrical parameters include a typical supply current of 4mA, shutdown current under 10µA, and driver propagation delays of 20ns.

Drivers, Receivers, Transceivers Feature Summary

• Integrated hot-swap capability prevents false transitions during power-up or hot insertion
• True fail-safe receiver ensures logic-high output when inputs are shorted or open
• High electrostatic discharge tolerance protects against ±35kV HBM events
• Low-power shutdown mode reduces supply current to less than 10µA

Drivers, Receivers, Transceivers Applications

• Motion Controllers
• Field Bus Networks
• Encoder Interfaces
• Backplane Busses

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'UA' corresponds to the 8-pin µMAX package configuration. Confirm the operating temperature range aligns with industrial requirements (-40°C to +125°C). Ensure the voltage supply constraints match the application's bus speed needs, as higher voltages reduce the maximum supported data rate.

Drivers, Receivers, Transceivers Selection Notes

Select this component for high-speed RS-485 applications requiring robust ESD protection and extended temperature ranges. Consider the trade-off between data rate and supply voltage; lower voltages support higher speeds. Verify that the 8-pin µMAX footprint fits the design constraints compared to SOIC or TDFN alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14783E family of high-speed RS-485 transceivers. It shares core features like ESD protection and fail-safe receivers with other variants but differs in package type and thermal characteristics. The EAUA variant specifically utilizes the µMAX package for compact surface-mount designs.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include MAX14783EESA+ (SO package) and MAX14783EEUA+ (µMAX package, 85°C range). Cross-package replacements require verifying pin compatibility and thermal performance differences.
