LTC2862HDD-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862HDD-1#TRPBF is a half-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 20Mbps. The device features ±60V overvoltage fault protection on interface pins during all modes, including power-down. It supports an extended common mode range of ±25V and provides ±15kV ESD protection on interface pins. The component includes current-limited drivers, thermal shutdown, and guaranteed failsafe receiver operation.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults up to ±60V
• Extended common mode input range of ±25V
• Enhanced ESD protection on interface pins

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 this component. Confirm the H grade corresponds to the –40°C to +125°C operating temperature range required for your application environment. Ensure the DFN package footprint matches your PCB layout constraints before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this part for applications requiring high-speed 20Mbps communication with robust fault tolerance. The half-duplex configuration suits bidirectional bus topologies. Consider the DFN package for space-constrained designs. Verify that the ±60V protection level meets the specific electrical noise or ground loop conditions present in the target installation.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862 series of low-power RS485/RS422 transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The HDD suffix denotes the 8-lead plastic DFN package, while the TRPBF suffix specifies tape and reel delivery format.
