74HC165 Shift Register (Parallel in Serial Out) 

Here is a great video that shows the use of the 74HC165 (parallel in serial out) shift register: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yna3iJa1hzg.html

Good explanation video mate; I like how you explain the theory then put it into practice!

I liked your video, easy to understand because it's a very clear explanation, you got my sub, thanks.

Interesting way to interface old 8bits ports to communicate with serial eproms, wondering wich circuit would do the reverse way, get the serial signal and convert to parallel 8bits !

Not for the beginner or Analog guys. :)
