![]() ![]() Perhaps, we will illuminate four LEDs (Light Emitting Diodes) with the four outputs (QA QB QC QD). The practical application of the serial- in/parallel- out shift register is to convert data from serial format on a single wire to parallel format on multiple wires. ![]() If four data bits are shifted in by four clock pulses via a single wire at data- in, below, the data becomes available simultaneously on the four Outputs QA to QD after the fourth clock pulse. Therefore, a serial- in/parallel- out shift register converts data from serial format to parallel format. It is different in that it makes all the internal stages available as outputs. Serial- in, Parallel- out Shift Register : Shift Registers A serial- in/parallel- out shift register is similar to the serial- in/ serial- out shift register in that it shifts data into internal storage elements and shifts data out at the serial- out, data- out, pin. ![]()
