LTC2863HDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863HDD-2#PBF is a full-duplex RS485/RS422 transceiver from Analog Devices, housed in an 8-lead DFN package. It supports a maximum data rate of 250kbps with a supply voltage range of 3V to 5.5V. The device features ±60V fault protection on transmission lines and operates within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on data lines during all operational modes, including power-down.
• Features ±15kV ESD protection on interface pins and ±8kV on other pins for reliable operation in harsh environments.
• Includes extended common mode range of ±25V and guaranteed failsafe receiver operation to maintain data integrity.
• Offers current-limited drivers and thermal shutdown protection to prevent damage during short-circuit or overload conditions.

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA) systems
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC controls

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'HDD' corresponds to the 8-lead DFN package and '-2' indicates the 250kbps slew-rate limited data rate. Confirm the '#PBF' designation ensures lead-free compliance and RoHS adherence. Cross-reference the manufacturer's ordering guide to ensure availability matches the required industrial temperature grade.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside high fault tolerance. The 250kbps rate suits applications prioritizing low electromagnetic interference over high-speed throughput. Ensure the system ground loop voltages remain within the ±25V common mode limit to utilize the extended operating range effectively.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2863 family, which provides full-duplex RS485/RS422 connectivity. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'H' suffix denotes the extended industrial temperature range, while the 'D' indicates the DFN package style.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with the LT1785 and LT1791. Verify that substitute components support the same ±60V fault protection and full-duplex architecture to ensure direct interchangeability without circuit redesign.
