I need use an shift register, but instead of the typical serial in/parallel out, the inverted functionality, parallel in/serial out. So, there is an several options, like the MC74HC165A. My plan is use two of them and tied to MISO line, but this chip can't put it's output to high-impedance state, so what happens with the MISO line?? I guess that if the MC74 force it's output to LOW, the other slaves on the bus can't be able to TX, right?
If I chain the output of the shift register with an 3-state buffer, would work?
