Parallel loading, in ways, can be viewed as simpler, because you can shift all the data in at one time. So, in recap, it shifts in all data at one time and shifts the data out one a time. So the 74HC165 allows parallel loading on the input side and on the output side shifts bits out serially, meaning Loading allows us to input all 8 bits together during one clock cycle, while serial loading only allows 1 bit to be shifted
This is contrast to serial loading, in which only one bit can be shifted in at a time. Parallel-loading means that all the 8 bits can be loadedĪll together at one time. The 74HC165 register is a parallel-load, serial-out register. In this project, we will build a register circuit using a 74HC165 chip.
