  • In such types of operations, the data is entered serially and taken out in parallel fashion.

  • Data is loaded bit-by-bit. The output(s) are disabled as long as the data is loading.

  • As soon as the data loading gets completed, all the flip-flops contain their required data. The output(s) are enabled so that all the loaded data is made available over all the output lines at the same time.

  • 4 clock cycles are required to load a four-bit word. Hence the speed of operation of SIPO mode is the same as that of the SISO mode.
