Welcome to PhysicsForums!

When trying to decipher the operation of an IC (in this case, a shift register), one of the first (and often the best) places to go is the datasheet:

You can find a truth table as well as a timing diagram within the datasheet which should allow you to decipher the operation of the shift register and answer your questions. Here at PhysicsForums, we can't give you answers to homework, but will try to help you through them.

If you don't have much exposure to shift registers, here's the Wikipedia article:

The 74HCT597 is a 8-bit shift register and storage register integrated circuit (IC). It is used to store and manipulate digital data in electronic circuits. The component is composed of two main parts, the shift register and the storage register, as shown in Figures 1 and 2.

The shift register is responsible for shifting data in a serial manner, while the storage register is used to store the data in parallel. The shift register consists of a chain of flip-flops, which are connected in a series to form a shift register. The function of the shift register is to receive and transfer data serially from one flip-flop to the next, allowing for the movement of data through the circuit.

The storage register, on the other hand, is made up of latches, which are used to store and hold the data in parallel. This allows for the data to be accessed and manipulated by other components in the circuit. The storage register also has a clock input, RCK, which is used to control the transfer of data from the shift register to the storage register.

The use of two circuits 74HCT597 allows for the efficient acquisition of input data. The shift register is used to receive and shift the data, while the storage register is used to store and hold the data in a parallel form. This allows for faster processing of data and easier manipulation of the input data by other components in the circuit.

The RCK input of the storage register plays a crucial role in controlling the data transfer from the shift register to the storage register. When the RCK input is triggered, the data in the shift register is transferred to the storage register, allowing for the data to be stored and accessed by other components.

The other inputs, /SRCLR, SRCK, and /SRLOAD, are used to control the operation of the shift register. /SRCLR is used to clear the shift register, SRCK is used to shift the data, and /SRLOAD is used to load the data into the first cell of the shift register.

The SER input of the first cell of the shift register is used to input the data into the shift register. This data is then shifted through the rest of the cells in the shift register, allowing for the data to be manipulated and stored in the storage register.

In conclusion, the 74HCT597 is an important component in electronic circuits, allowing for the efficient acquisition, manipulation, and
