Piso Shift Register Circuit. This circuit consists of three d flip flops which are cascaded. The parallel in serial our shift register is also called piso shift register.
Ic 4014 8 stage shift register. The circuit consists of four d flip flops which are connected. Figure 1 shows a piso shift register which has a control line and combinational circuit and and or gates in addition to the basic register components flip flops fed with clock and clear pins.
More likely it will be driven by something else compatible with this serial data format for example an analog to digital converter a temperature sensor a keyboard scanner a serial read only memory.
Parallel in serial out piso shift register. Parallel in serial out piso shift register. The parallel in serial our shift register is also called piso shift register. The ser line of the shift register may be driven by another identical cd4021b circuit if more switch contacts need to be read.
