MAX14787EGSA+

Drivers, Receivers, Transceivers Overview

The MAX14787EGSA+ is a full-duplex RS-485 transceiver designed for robust communication in harsh industrial environments. It operates from a 3.0V to 5.5V supply with a maximum no-load supply current of 4mA. The device features ±35kV ESD protection on the RS-485 pins and supports data rates up to 500kbps. It includes slew-rate limited outputs, an integrated receiver deglitch filter, short-circuit protected outputs, true fail-safe receiver functionality, and thermal shutdown. The component is housed in an 8-pin SO package and operates within a temperature range of -40°C to +105°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated receiver deglitch filter enhances noise immunity for signals with slow rise and fall times.
• Slew-rate limited driver minimizes electromagnetic interference (EMI) and reduces reflections on improperly terminated cables.
• True fail-safe receiver guarantees a logic-high output when inputs are open or shorted.
• Thermal shutdown circuitry protects drivers against excessive power dissipation by forcing outputs into a high-impedance state.

• Utility Meters

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. Ensure the selected variant matches the required operating temperature range and data rate specifications for the target application environment. Cross-reference the manufacturer's latest documentation to confirm availability and any potential design changes.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 communication with high ESD protection and noise immunity. The MAX14787E is optimized for space-constrained designs using an 8-pin SO package. Consider the MAX14789E if a higher data rate of 25Mbps is needed without slew-rate limiting. Verify that the 3V to 5.5V supply voltage aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

The MAX14787EGSA+ belongs to the MAX14784E/MAX14786E/MAX14787E/MAX14789E family of full-duplex RS-485 transceivers. This series is engineered for high-speed communication in demanding industrial settings. The family offers variations in data rates, package sizes, and feature sets such as slew-rate limiting and deglitching to suit different design requirements.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14789EGSA+ is a confirmed substitute within the same family, offering 25Mbps data rate capability but lacking slew-rate limiting and deglitch filtering. Both devices share the 8-pin SO package and similar electrical characteristics.

Drivers, Receivers, Transceivers FAQ

Does the MAX14787EGSA+ support half-duplex operation?

Yes, the device can be configured for half-duplex applications by connecting the Y output to the A input and the Z output to the B input.

What is the purpose of the integrated receiver deglitch filter?

The deglitch filter reduces false triggers caused by noise when data is transmitted over long cables or when differential signals have very slow rise and fall times.

How does the device protect against short circuits?

The driver outputs are short-circuit current-limited, and thermal shutdown circuitry forces the outputs into a high-impedance state if the die temperature exceeds approximately +160°C.
