LTC2862HDD-2#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2862HDD-2#TRPBF is a half-duplex RS-485/RS-422 transceiver manufactured by Analog Devices Inc. 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, ±15kV ESD on interface pins, and an extended common mode range of ±25V. It utilizes an 8-lead DFN package with exposed pad and functions within a -40°C to +125°C temperature range.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±60V overvoltage fault protection on transmission lines during all operational modes
• Enhanced electrostatic discharge tolerance with ±15kV HBM rating on interface pins
• Extended common mode input range supporting operation in high ground loop voltage environments
• Guaranteed failsafe receiver operation ensuring logic high output under open or shorted bus conditions

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA) systems
• Industrial control and instrumentation networks
• Automotive and transportation electronics
• Building automation, security systems, and HVAC controls

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the 'H' grade designation matches the required industrial temperature range for the target application environment. Ensure compatibility with existing PCB footprints for the 8-lead DFN package configuration.

Drivers, Receivers, Transceivers Selection Notes

Select this model for applications requiring robust fault protection against line faults up to ±60V. The 250kbps slew-rate limited mode is suitable for reducing electromagnetic interference in sensitive environments. Verify that the half-duplex architecture aligns with the system's communication protocol requirements compared to full-duplex alternatives.

Drivers, Receivers, Transceivers Part Context
