LTC2863CDD-2#PBF

Drivers, Receivers, Transceivers Overview

The LTC2863CDD-2#PBF is a full-duplex RS485/RS422 transceiver in an 8-lead DFN package. It operates on a 3V to 5.5V supply with a maximum data rate of 250kbps. The device features ±60V fault protection and an extended common mode range of ±25V. It includes ±15kV ESD protection on interface pins, guaranteed failsafe receiver operation, and thermal shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication with dedicated driver and receiver channels
• Robust overvoltage tolerance up to ±60V on transmission lines
• Low electromagnetic interference via slew-rate limited data transmission
• High input impedance supporting extensive network node counts

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Building automation and HVAC systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific temperature grade suffix 'C' corresponds to the commercial 0°C to 70°C operating range required for the application. Confirm the DFN package dimensions match the PCB footprint design. Ensure the logic select pin configuration aligns with the low-speed 250kbps mode requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex capability is necessary alongside high fault tolerance. The 250kbps mode is suitable for applications prioritizing low EMI over high throughput. Verify that the 8-lead DFN package fits within the spatial constraints of the target design compared to SOIC alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of rugged transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'C' suffix denotes the commercial temperature grade, while 'IDD' indicates the specific DFN package variant within the Analog Devices portfolio.

Drivers, Receivers, Transceivers Replacement Considerations

LTC2863HDD-2#PBF offers the same electrical specifications but supports an extended industrial temperature range of -40°C to 85°C. LTC2863IS8-2#PBF provides identical functionality in an 8-lead SOIC package instead of the DFN form factor.
