Working Principles

The 74HCT194D,653 is a serial-in, parallel-out shift register. It receives data serially and stores it in its internal memory. On each clock pulse, the stored data is shifted to the next stage, while new data is entered at the first stage. After all clock pulses have been applied, the parallel outputs reflect the serial input.
