RS-485 / RS-232 Multiprotocol Transceiver Reference Design

TIDA-00540

Design files

Overview

This design (TIDA-00540) allows for communication over RS-485 or RS-232 data buses without requiring separate wiring for each.  Data lines are shared between two different transceiver types, and a single control signal is used to determine which protocol is to be used.

Features
  • Same interconnects can be used for both RS-485 and RS-232 communication
  • Easy control of active protocol
  • On-board TVS diodes for protection against overvoltage transients
  • Compact size and minimum number of components
  • This circuit is designed and tested, and its performance is documented in a test report.
Industrial

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
