Hello all!
I am use RF UART into a project. I am using a PIC16F690 as microcontroller and RF digital RFD21733. The pic16f690 is 5v and the rfd21733 is 3.3v. I would like use a TXB0104 level convertor to send data and receive data over the serial communications of UART. I have has anyone done this? In reading the data sheet I am not able to understand how I would hook up this TXB0104 convert my logic levels. Every thing done has not worked and dont want to wreck rf module as they expensive.
Thank you help me with this.

 

I forgot say that I use mode 2 on rfmodule to communicate with another pic 16f690.

 

Upload the datasheets. All three of them.
