LTC2863CDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2863CDD-1#TRPBF is a full-duplex RS485/RS422 transceiver manufactured by Analog Devices Inc. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. The device features ±60V fault protection on the transmission lines, ensuring robustness against overvoltage conditions during all operational modes. It includes ±15kV ESD protection on interface pins and an extended common mode range of ±25V. Packaged in an 8-lead DFN with an exposed pad, it is designed for industrial environments requiring high reliability.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V fault protection on data lines during power-down and active operation
• Features ±15kV HBM ESD protection on A/B/Y/Z pins without latchup
• Supports extended common mode input range from -25V to +25V
• Guarantees failsafe receiver operation when inputs are open or shorted

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 ordering suffix #TRPBF indicates tape and reel packaging rather than tube packaging. Confirm the temperature grade 'C' corresponds to the commercial range of 0°C to 70°C as defined in the manufacturer's selection guide. Ensure the DFN package variant matches the required footprint for the design.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with high-speed data rates up to 20Mbps. It is suitable for designs needing integrated overvoltage protection without external components. Consider the thermal performance of the DFN package and ensure adequate PCB copper area connected to the exposed pad for heat dissipation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of rugged transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'CDD-1' designation specifies the commercial temperature grade, DFN package, and full-duplex configuration with a 20Mbps data rate capability.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2863IDD-1#TRPBF offers the same electrical specifications but with an extended industrial temperature range (-40°C to 85°C). LTC2863HDD-1#TRPBF provides a high-temperature grade (-40°C to 125°C). Both are direct pin-compatible replacements if thermal requirements exceed the commercial grade limits.
