LTC2864IDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2864IDD-1#TRPBF is a full-duplex RS485/RS422 transceiver in a 10-lead DFN package. It operates on a 3V to 5.5V supply and supports data rates up to 20Mbps or low EMI 250kbps. The device features ±60V fault protection on transmission lines, ±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

• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC
• Medical equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix IDD-1 against the manufacturer's ordering guide to confirm the industrial temperature grade (-40°C to 85°C) and tape-and-reel packaging format. Ensure the component matches the 10-lead DFN footprint requirements for the target PCB design.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring full-duplex communication with robust fault tolerance. The IDD-1 variant provides the necessary industrial temperature range and surface-mount packaging. Verify that the system ground loop voltages remain within the ±25V common mode specification.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC286x family of fault-protected transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The 'HDD' suffix indicates the military-grade temperature range, while 'IDD' specifies the industrial range.

Drivers, Receivers, Transceivers FAQ

Does the LTC2864 provide overvoltage protection when powered down?

Yes, the device maintains ±60V fault protection on the data transmission lines even during power-down conditions.

What is the maximum number of nodes supported by this transceiver?

The high input impedance allows the network to support up to 256 nodes.

How does the failsafe feature operate?

It guarantees the receiver output will be in a logic 1 state if inputs are shorted, left open, or terminated but not driven, provided the condition persists for more than approximately 3µs.
