LTC2863IDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2863IDD-1#TRPBF is a full-duplex RS485/RS422 transceiver operating on a 3V to 5.5V supply. It supports data rates up to 20Mbps and features ±60V fault protection on transmission lines during all modes, including power-down. The device provides ±15kV ESD protection on interface pins and an extended common mode range of ±25V. It includes guaranteed failsafe receiver operation, high input impedance supporting 256 nodes, current-limited drivers, and thermal shutdown.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V

• High input impedance supports up to 256 nodes on the bus

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 indicates tape and reel packaging when sourcing components. Confirm that the IDD designation corresponds to the industrial temperature range of –40°C to +85°C for your application requirements. Ensure compatibility with the DFN-8 package dimensions during PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault tolerance against large ground loop voltages. The full-duplex architecture is suitable for simultaneous bidirectional communication. Verify that the system logic levels align with the VCC supply voltage, as the LTC2863 lacks a separate logic supply pin unlike the LTC2865.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC286x family of low-power, fault-protected transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791, facilitating direct upgrades in existing designs. The IDD variant specifically denotes the industrial temperature grade housed in an 8-lead DFN package.

Drivers, Receivers, Transceivers FAQ

Does the LTC2863 have a separate logic supply pin?

No, the LTC2863 uses the primary VCC supply for both the driver/receiver and logic inputs. A separate logic supply pin (VL) is only available on the LTC2865.

What is the maximum data rate supported by this device?

The LTC2863 supports a maximum data rate of 20Mbps.
