Is it possible to connect the BU2099 serial IN/parallel OUT driver IC in a cascade connection? And are there any precautions?
- The BU2099 supports cascade connection by inputting the serial data output pin (SO) of the 1st stage IC to the data of the second stage IC. SO changes at the falling timing of the CLK, so the second stage takes in the SO output as data at the rising clock edge, similar to the first stage.
