MAX14782EATA+T

Drivers, Receivers, Transceivers Overview

The MAX14782EATA+T is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-pin TDFN-EP package. It supports data rates up to 500 kbps and operates within a supply voltage range of 3 V to 5.5 V. The device features robust protection with 35 kV Human Body Model (HBM) ESD performance on the bus pins. Designed for industrial environments, it functions reliably across an extended temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides high electromagnetic interference immunity through integrated receiver input hysteresis.
• Ensures fail-safe operation by maintaining a defined logic-high output state when inputs are open or floating.
• Delivers superior electrostatic discharge resilience with 35 kV HBM protection on all bus lines.

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring reliable communication in electrically noisy environments.
• Building automation systems utilizing PROFIBUS or Modbus protocols.
• Process control instrumentation connected via RS-485 serial buses.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' and tape-and-reel designation '+T' against official manufacturer documentation to confirm the exact packaging format and lead-free status. Ensure the component matches the required thermal pad specifications for proper PCB mounting and heat dissipation during integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require moderate data speeds alongside extreme ESD tolerance. It is suitable for applications where standard transceivers may fail due to static discharge events. Confirm that the 500 kbps speed meets the network timing requirements before finalizing the design.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX14782E series of robust RS-485 transceivers. It shares functional similarities with other devices in the family but is distinguished by its specific pinout and package configuration. The series is engineered to address common failure modes in harsh industrial settings.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the MAX14782EASA+T variant, which utilizes an SOIC-8 package instead of TDFN. Verify pin compatibility and thermal characteristics when considering alternative packages within the same product line.
