Don’t forget to tie OE low and SRCLR bit high for everything to work properly :-) Crazy fast too. Times for shifting are in tens of nanoseconds.
The 75HC595 shift register is a great and fast way to add I/O pins to your microcontroller. It only requires 3 pins to drive it and has an unlimited number of outputs, assuming you have enough chips.
