6 MODE Configurations for THVD4431

THVD4431 can be configured into various modes through the MODE pins. Below are the diagrams that explain those modes. THVD4431 greatly benefits the application by reducing test and qualification time and re-use of schematics and layout, as the device can be used for any mode via pin control. Notice that same bus and logic pins are used whether the device is operating in any RS-232 or in any RS-485 modes.
