MAX14786EAUD+T

Drivers, Receivers, Transceivers Overview

The MAX14786EAUD+T is a full-duplex RS-485 transceiver designed for high-speed communication in harsh industrial environments. It operates from a 3.0V to 5.5V supply with a maximum no-load supply current of 4mA and features ±35kV ESD protection on the RS-485 pins. The device supports data rates up to 25Mbps, includes true fail-safe receiver circuitry, and offers thermal shutdown protection. It is housed in a 14-pin TSSOP package and operates over an extended temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Supports full-duplex or half-duplex configurations with flexible driver and receiver enable/disable control.
• Provides robust signal integrity through integrated receiver deglitch filtering and true fail-safe operation.
• Features enhanced durability with ±35kV HBM ESD protection and short-circuit protected outputs.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'AUD' corresponds to the 14-pin TSSOP package variant when sourcing. Confirm that the '+T' designation indicates reel packaging. Ensure compatibility with the required operating voltage range and environmental conditions before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed RS-485 communication up to 25Mbps. It is suitable for systems needing extended temperature operation and strong ESD immunity. Consider the 14-pin TSSOP footprint for space-constrained designs requiring full-duplex capability.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1478xE family of full-duplex RS-485 transceivers. It shares core features like ESD protection and fail-safe receivers with siblings such as the MAX14784E and MAX14789E, but differs in speed capabilities and package options.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional substitutes within the same family include the MAX14786EASD+ (14-pin SO) and MAX14789EGSA+ (8-pin SO). Verify pinout compatibility and package dimensions when considering these alternatives.

Drivers, Receivers, Transceivers FAQ

Does the MAX14786EAUD+ support half-duplex operation?

Yes, although it is a full-duplex transceiver, it can be configured for half-duplex by connecting the Y output to the A input and the Z output to the B input.

What is the maximum data rate supported by this device?

The MAX14786EAUD+ supports a maximum data rate of 25Mbps under standard loading conditions.

How does the device handle open or shorted receiver inputs?

It features true fail-safe circuitry that guarantees a logic-high receiver output when the inputs are open, shorted, or connected to a terminated line with all drivers disabled.
