Hello everyone!
I found some 74hc165 IC. The first thing that came to my mind was how to use it with 74hc595. But it seems to me it doesn't have the same functions as the 74hc595. Can I use 74hc165 instead of 74hc595?
The 165 performs the opposite function from the 595. The 595 lets you shift 8 bits in one at a time, then output all 8 bits in parallel. The 165 lets you load 8 bits at once, then shift them out one at a time. So the 595 is serial-in, parallel-out, but the 165 is parallel-in, serial-out.

You can always Google a datasheet for a part like that.
