What product types are included in the mobile registers?

In digital circuits, the circuit used to store binary data or code is called a shift register.

Registers are composed of triggers with storage capabilities. A trigger can store one bit binary code and a register for N bit binary code, which consists of n triggers.

Shift registers can be roughly divided into four types according to the input/output connection mode, including: Serial Input Serial Output Type (SISO), Serial Input Serial Output Type (SISO), Parallel Input Serial Output Type (PISO), Parallel Input Parallel Output Type (PIPO).

The SISO shift register, with the shift direction left or right, is the most basic form of the shift register, which displaces the trigger step by step each time a clock signal is applied. Since each trigger locks 1 bit of data, four of them are used as 4-bit displacement registers. This also means that they will be output in the same order as the input signal.

SIPO shift registers are used to convert serial and parallel signals. The data in the input shift register is one bit, but the data locked in the trigger can be collected at the output, i.e. sent out through parallel transmission.

PISO shift registers are used to convert between serial and parallel signals. When using PISO shift registers, multiple input signals need to be loaded at once. In addition, LOW and other controls are required to write data through the clock signal, and HIGH shift bits are required, but if only the first trigger is input, it can also be used as the SISO shift register mentioned above. Yes, it is possible.

Like PISO, PIPO shift registers load multiple input signals into the shift registers, and when the clock signal becomes high, they shift to their respective output simultaneously. It is used to lock specific information, such as backup history.
