Working Principles

The MM74HC589SJ operates based on the principle of serial-in, parallel-out shifting. It receives data serially through the Ds pin and shifts it into the internal register upon receiving a clock pulse at the CP pin. The shifted data can then be accessed in parallel through the Q0-Q7 pins. The storage enable (STCP) and shift enable (SHCP) inputs control the storage and shifting operations, respectively. The clear (MR) input resets the register to its initial state.
