MAX14786EASD+T

Drivers, Receivers, Transceivers Overview

The MAX14786EASD+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 I/O ports. The device supports data rates up to 25Mbps, offering low propagation delay and tight output skew. It includes true fail-safe receiver circuitry, short-circuit protected outputs, and thermal shutdown. Available in a 14-pin SO package, it 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 independent driver and receiver enable controls
• Provides robust signal integrity through true fail-safe receivers that guarantee a logic-high state when inputs are open or shorted
• Features integrated thermal shutdown and short-circuit current limiting to protect against excessive power dissipation and bus faults

Drivers, Receivers, Transceivers Applications

• Motion Controllers
• Encoder Interfaces
• HVAC Control Systems
• Utility Meters

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the package type and RoHS compliance status. Ensure the selected variant matches the required operating temperature range and pin configuration for the target PCB layout. Cross-reference the manufacturer's latest documentation to confirm active production status and any potential design changes.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed data transmission up to 25Mbps alongside strong electrostatic discharge immunity. It is suitable for systems needing flexible half-duplex or full-duplex operation within a wide voltage range. Consider the 14-pin SO package constraints and thermal performance characteristics during the initial hardware design phase.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14784E/MAX14786E/MAX14787E/MAX14789E family of full-duplex RS-485 transceivers. While sharing common interface standards and protection features, variants differ in maximum data rates, slew-rate limitations, and package options. This specific model provides the highest speed option within the 14-pin form factor.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX14784EASD+T serves as a lower-speed alternative within the same package. The MAX14786EAUD+T offers identical electrical performance but utilizes a 14-pin TSSOP package instead of SO.
