LTC2863CDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2863CDD-2#TRPBF is a full-duplex RS485/RS422 transceiver from Analog Devices, operating on a 3V to 5.5V supply. It features ±60V fault protection on data lines and supports a maximum data rate of 250kbps with low EMI characteristics. The device includes ±15kV HBM ESD protection on interface pins and an extended common mode range of ±25V. Packaged in an 8-lead DFN (3mm × 3mm) with an exposed pad, it operates within a temperature range of 0°C to 70°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on transmission lines during all operational modes, including power-down.
• Features fully balanced differential receiver thresholds to ensure low duty cycle distortion and enhanced noise immunity.
• Includes current-limited drivers and thermal shutdown mechanisms to protect against short circuits and excessive power dissipation.

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• Industrial control and instrumentation networks
• Automotive and transportation electronics

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF confirms tape and reel packaging rather than tube packaging. Confirm the C-grade designation matches the required 0°C to 70°C operating temperature for your application environment. Ensure the DFN package footprint aligns with your PCB layout constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with a fixed 250kbps low EMI data rate. Choose this variant over the -1 version if half-duplex operation is not needed. Verify that the 3V to 5.5V VCC supply range meets your system's power requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of rugged RS485/RS422 transceivers. It shares pin compatibility with older LT1785 and LT1791 series devices while offering improved fault tolerance and ESD protection specifications.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate for the LTC2863-2 variant?

The LTC2863-2 variant is limited to a maximum data rate of 250kbps to provide low EMI performance.

How does the failsafe feature operate on this transceiver?

The receiver guarantees a logic 1 state when inputs are shorted, open, or terminated but undriven, provided the condition persists for more than approximately 3µs.

What is the ESD protection rating for the interface pins?

The A, B, Y, and Z interface pins are protected to ±15kV Human Body Model (HBM) without latchup or damage.
