I'm wondering if i can constantly convert an 8 bit parallel stream of data to serial?

I have a main clock, and a divide by 8 clock. On every 8 clock pulse i want to "load" the next 8 bits of parallel data. But i want to constantly keep shifting out the serial data without stopping.

I'm wondering if i can use a 74HC165 to achieve this I'm not sure if this is possible, and I can't understand how to load the next 8 bits.

I hope this makes some sense.

74HC597 is a better choice because it has an input latch.

I believe this could be arranged. At least I have a plan in mind.

What is the main clock frequency?

Sure, it's basically called SPI.
