I have a question about the interface of 3 devices connected to UART.
Device A's I/O control is done by FPGA, and it processes UART TX and RX signals of devices B and C.
I am trying to connect FPGA and Device B (or Device C) by using the non inverting buffer SN74LVC1T45.
Device B inputs/outputs 3.3V level UART signals with TXB0108 chip, and device C inputs/outputs 5V level UART signals with TXS0102 chip.
I want to use SN74LVC1T45 buffer as below.
In this case, the buffer can drive the TXS and TXB chips with sufficient current, and is there any problem with UART communication?
Or, please introduce a chip that can be used instead of SN74LVC1T45.
Devices B and C have already been manufactured, so it is difficult to change the TXS and TXB chips.
Thank you in advance.
Best regards.
