LTC2871CFE#PBF

Drivers, Receivers, Transceivers Overview

The LTC2871CFE#PBF is a robust pin-configurable multiprotocol transceiver supporting RS232, RS485, and RS422 protocols on a single 3V to 5.5V supply. It integrates two independent RS232 transceivers and one RS485 transceiver on dedicated I/O lines. The device features software-selectable interface modes, half-/full-duplex RS485 switching, and logic loopback mode for diagnostics. An integrated DC/DC boost converter eliminates the need for multiple supplies. It supports up to 256 RS485 nodes with full failsafe operation and high ESD protection of ±16kV.

Drivers, Receivers, Transceivers Feature Summary

• Integrated termination resistors allow easy interface reconfiguration without external components
• Supports simultaneous RS232 and RS485 protocols with dedicated I/O lines
• Built-in DC/DC boost converter generates required voltages from a single supply

Drivers, Receivers, Transceivers Applications

• Point-of-Sale Terminals
• Cable Repeaters
• Protocol Translators

Drivers, Receivers, Transceivers Procurement Notes

Verify the package type matches the design requirements, as this specific part number corresponds to the 38-lead TSSOP variant. Confirm that the commercial temperature grade (0°C to 70°C) aligns with the operational environment constraints. Ensure all control pins are properly terminated to prevent floating states during operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when independent control of two RS232 channels and one RS485 channel is required on separate pins. Consider the LTC2870 if shared I/O lines or different pin counts are acceptable. Verify that the 3V to 5.5V supply range covers the system voltage rails and that the 38-pin footprint fits the PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This component belongs to the LTC2870/LTC2871 family of multiprotocol transceivers. While the LTC2870 offers configurable combinations on shared lines, the LTC2871 provides dedicated I/O for its two RS232 and one RS485 transceivers. Both devices share similar internal architectures including integrated termination and boost converters.
