LTC2863IS8-2#TRPBF

Drivers, Receivers, Transceivers Overview

The Analog Devices LTC2863IS8-2#TRPBF is a full-duplex RS485/RS422 transceiver operating on a 3V to 5.5V supply. It features ±60V fault protection and an extended common mode range of ±25V. The device supports a maximum data rate of 250kbps with low EMI characteristics. It includes ±15kV ESD protection on interface pins, guaranteed failsafe receiver operation, and high input impedance supporting up to 256 nodes. Packaged in an 8-lead SOIC (S8) format, it operates within a temperature range of –40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Protected from overvoltage line faults to ±60V during all modes of operation
• Enhanced ESD protection allows withstand of ±15kV HBM on interface pins without latchup
• Extended common mode range of ±25V improves reliability in electrically noisy environments
• Fully balanced differential receiver thresholds ensure low duty cycle distortion

Drivers, Receivers, Transceivers Applications

• Supervisory Control and Data Acquisition (SCADA)
• 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 ordering suffix #TRPBF indicates tape and reel packaging when sourcing this component. Confirm that the IS8 designation matches the required industrial temperature grade for your deployment environment. Ensure the full-duplex configuration aligns with the system architecture requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select the LTC2863 variant specifically for full-duplex communication needs requiring separate transmit and receive lines. Choose the -2 suffix version when low EMI transmission at 250kbps is prioritized over higher speed data rates. Verify that the 8-lead SOIC package dimensions fit the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of rugged transceivers. It shares pin compatibility with legacy parts like the LT1785 and LT1791. The series addresses industrial needs for fault-tolerant communication where standard RS485 devices might fail due to ground loop voltages or electrical noise.

Drivers, Receivers, Transceivers Replacement Considerations

LT1785 and LT1791 are confirmed pin-compatible replacements.
