Working Principles

The MC74HC589AFELG operates based on the principles of shift registers. It uses clock signals to shift data bits in and out of the register. When the shift clock (SHCP) is pulsed, the data at the serial input (DS) is shifted into the register, while the existing data is shifted to the next stage. On the other hand, when the storage clock (STCP) is pulsed, the data in each stage is latched and held until the next pulse.
