MAX14783EEUA+T

Drivers, Receivers, Transceivers Overview

The MAX14783EEUA+T is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a supply voltage range of 3.0V to 5.5V and supports data rates up to 30Mbps in the 8-pin µMAX package. The device features ±35kV HBM ESD protection, true fail-safe receiver inputs, and hot-swap capability. It includes low-power shutdown mode with a maximum current draw of 10µA. The component operates within a temperature range of -40°C to +85°C.

• Integrated high-voltage electrostatic discharge protection on A and B pins
• True fail-safe receiver guarantees logic-high output during input short or open events
• Hot-swap functionality prevents false transitions during power-up or board insertion
• Low-power shutdown mode reduces supply current consumption

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix EEUA against official documentation to confirm the 8-pin µMAX package type and the -40°C to +85°C operating temperature range. Ensure compatibility with the required 30Mbps maximum data rate specification for the target application environment before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD tolerance and reliable operation in multipoint bus environments. Consider the 30Mbps speed limit and 8-pin µMAX footprint constraints. Evaluate thermal dissipation requirements relative to the junction-to-ambient resistance specified for the µMAX package under expected load conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14783E family of high-speed RS-485 transceivers. It shares core functional characteristics with variants like the MAX14783EESA+T but differs in physical packaging and specific performance limits dictated by the µMAX form factor. The family emphasizes industrial-grade noise immunity and integrated protection mechanisms.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other MAX14783E variants such as MAX14783EESA+T, provided the system accommodates the SOIC package and higher 40Mbps data rate capability. Verify pinout compatibility and ensure the replacement meets the specific thermal and electrical requirements of the existing design.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate for the MAX14783EEUA+T?

The maximum data rate for the MAX14783EEUA+T in the 8-pin µMAX package is 30Mbps.

How does the device handle hot-swap conditions?

The device features integrated hot-swap inputs that hold the driver disabled and receiver enabled during power-up, preventing false transitions on the bus during board insertion or power sequencing.

What is the fail-safe behavior of the receiver?

The true fail-safe receiver guarantees a logic-high output at RO when the differential receiver inputs (A-B) are shorted, open, or connected to a terminated line with all drivers disabled.
