7 Application Diagrams for THVD4431

As described earlier, THVD4431 can be configured for RS-485 half duplex network, RS-485 full duplex network or RS-232 3T5R point-to-point communication. Notice how each node in the RS-485 network uses THVD4431, end nodes with on-chip termination engaged and middle nodes with on-chip termination switched off.
