MAX14783EASA+T

Drivers, Receivers, Transceivers Overview

The MAX14783EASA+T is a half-duplex RS-485 transceiver in an 8-pin SO package. It operates on a 3.0V to 5.5V supply and supports data rates up to 42Mbps at 3.0V–3.6V, or 16Mbps at 3.0V–5.5V. The device features ±35kV HBM ESD protection, ±20kV air-gap IEC 61000-4-2 protection, and short-circuit protected outputs. It includes true fail-safe receiver logic and hot-swap capability. Operating temperature ranges from -40°C to +125°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' indicates the 8-pin SO package variant. Confirm the operating temperature range matches the application requirements of -40°C to +125°C. Ensure the system voltage does not exceed the specified limits for the selected data rate configuration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust ESD immunity and high-speed communication over extended cable runs. Verify that the required data rate aligns with the supply voltage constraints defined in the electrical characteristics table. Consider the thermal dissipation capabilities of the SO package for the expected load conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14783E family of high-speed RS-485 transceivers. It shares functional similarities with other variants like the MAX14783EEUA+ and MAX14783EESA+, differing primarily in package type and maximum supported data rates across various supply voltages.

Drivers, Receivers, Transceivers Replacement Considerations

Public confirmed substitutes include MAX14783EEUA+ and MAX14783EESA+. Verify pin compatibility and ensure the replacement meets the specific data rate and temperature requirements of the design.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate at a 5V supply?

At a supply voltage between 3.0V and 5.5V, the maximum data rate is 16Mbps.

How does the device handle hot-swap events?

Internal circuitry holds the DE input low and RE input high during power-up, preventing false transitions on the bus until the external controller drives the signals.

What happens if the receiver inputs are shorted?

The true fail-safe receiver guarantees a logic-high output on RO when the differential input voltage (A-B) is greater than or equal to -10mV, covering shorted or open input conditions.
