LTC2863CS8-1#TRPBF

Drivers, Receivers, Transceivers Overview

The LTC2863CS8-1#TRPBF is a full-duplex RS-422/RS-485 transceiver manufactured by Analog Devices. It operates on a 3V to 5.5V supply voltage and supports data rates up to 20Mbps. 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 and high input impedance supporting up to 256 nodes. Packaged in an 8-lead SOIC (S8) with tape and reel shipping, it functions within a commercial temperature range of 0°C to 70°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
• High input impedance supports connection of up to 256 nodes on the network

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 confirms the tape and reel packaging format required for automated assembly processes. Confirm the CS8 designation corresponds to the 8-lead plastic SOIC package and the C grade indicates the specified commercial operating temperature range. Ensure compatibility with existing PCB footprints designed for this package style.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside robust fault tolerance. The 20Mbps data rate suits high-speed industrial applications. Verify that the 3V to 5.5V supply range matches the system power architecture. Consider the thermal characteristics and junction temperature limits if operating near the upper bounds of the commercial temperature range.

Drivers, Receivers, Transceivers Part Context

This part belongs to the LTC2862/LTC2863/LTC2864/LTC2865 family of low-power transceivers. The LTC2863 variant specifically provides full-duplex capability, distinguishing it from half-duplex models like the LTC2862. It shares pinout compatibility with legacy parts such as the LT1785 and LT1791, facilitating direct upgrades in existing designs requiring enhanced fault protection.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed pin-compatible replacements include the LT1785 and LT1791. Other members of the same family, such as the LTC2862 or LTC2864, may serve as functional alternatives depending on whether half-duplex or full-duplex operation is required.
