For a new design, we have planned to use four microcontroller's in a single board. Each microcontroller will transfer data in CAN to different peripherals from parallel port interface which is connected from Host. so each controller will act as 1 channel. Now we have planned to use UART interface for debugging for each controller. But in the front panel we are having less space so we have planned to use a single DB9 connector for accessing all 4 microcontrollers in UART interface by doing multiplex. It is required to select the UART channel through DIP switches or some other medium. But this should be configurable by the user in the front panel/on-board. Is it possible to use the SN74LV4052A IC for UART interface multiplexing? Attached the Logic Block diagram for your understanding. Please confirm my assumption is correct and also suggest some more options which should be more efficient and working without any crosstalk.
