Hello to all Piclisters,

I am designing a circuit which uses 3 shift-registers to spare some
microcontroller inputs. I actually use 74HC165 as a shift register, but
I found also CD4021. In practice, I found out that the data pin of each
register cannot be tied to a common data bus. Is there a solution to do
this ? (for 3 shift-registers, tie the Q7 data out pin to the same data
bus D0 pin, which is also common to other circuits).
