LTC2863HS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2863HS8-2#TRPBF is a full-duplex RS485/RS422 transceiver housed in an 8-lead plastic SOIC 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, ±15kV ESD on interface pins, and an extended common mode range of ±25V. Designed for harsh environments, it guarantees failsafe receiver operation and high input impedance supporting 256 nodes. The industrial temperature grade ensures reliable performance from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides ±60V overvoltage fault protection on transmission lines during all operational modes including power-down.
• Features robust ±15kV HBM ESD protection on interface pins and ±8kV on other pins without latchup.
• Supports extended common mode voltage range of ±25V with guaranteed failsafe receiver operation under open or shorted 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 suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm the HS designation corresponds to the required industrial temperature range for your application environment. Ensure compatibility with existing PCB footprints as this part is pin-compatible with legacy LT1785 and LT1791 devices.

Drivers, Receivers, Transceivers Selection Notes

Select this model for full-duplex applications requiring high-speed communication up to 20Mbps. The HS variant is appropriate for industrial settings demanding operation between -40°C and +125°C. Consider the 250kbps low EMI mode if electromagnetic interference mitigation is critical for the network topology.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of ruggedized transceivers. The LTC2863 specifically denotes a full-duplex configuration, distinguishing it from the half-duplex LTC2862. The HS suffix identifies the industrial temperature grade within the SOIC package lineup.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet confirms pin compatibility with LT1785 and LT1791 devices. Verify that substitute parts maintain the same ±60V fault protection rating and full-duplex architecture to ensure functional equivalence in existing designs.
