LTC1387 RS-232/RS-485 Multiprotocol Transceiver
Overview
The LTC1387CG#PBF is a multiprotocol interface IC from Analog Devices used for serial communications at 5 V. It is intended to support both RS-232 and RS-485-style interfacing, making it useful when a design needs to connect a UART to different physical layers.
Why Choose This Part
This part simplifies designs that need more than one serial standard by combining multiprotocol support in a single IC. Using a dedicated transceiver helps offload level shifting and line-driver requirements from the MCU, while keeping the interface compact and easy to integrate on a board.
Applications
Getting Started
Use it in a design with a standard UART on the logic side and follow the Analog Devices reference schematics and layout guidance for the chosen serial standard. For prototyping, an evaluation or reference design from Analog Devices is the most practical way to confirm line behavior, connector pinout, and any required external components before committing to a custom PCB.
