This article will discuss the application fields and working principles of the NLV74HC164ADTR2G Logic - Shift Register. The chip is a low-power, high-performance, 8-bit serial-in/parallel-out shift register capable of operating from -20°C to 85°C.The logic structure of the NLV74HC164ADTR2G is an 8-bit, synchronous serial-in/parallel-out shift register composed of eight data-storing flip-flops and their associated logic gates and enables the chip to transfer information serially. This differs from a conventional shift register where data is transferred parallel-in and parallel-out. With the NLV74HC164ADTR2G, serial data must be shifted in one bit at a time to store and shift out the data from the register.The NLV74HC164ADTR2G is used in applications that require the transfer of serial data such as for motion control, communication control, data acquisition, or where multiple bits of data need to be stored. It is also used in clocking applications, where information can be transferred in both directions.The NLV74HC164ADTR2G operates either in a serial transmission mode or in a parallel transmission mode. In the serial transmission mode, data is transmitted one bit at a time. In the parallel transmission mode, data is transmitted as a byte at a time. In either mode, the shift register functions as a serial-in/parallel-out device, with the bits stored in the register being outputted in parallel.The NLV74HC164ADTR2G has two clock inputs. The data input "SIN" is used to shift data into the register, while the data clock input "CIN" is used to clock the serial data through the register. Each time the clock signal is applied to the register, the data from the previous clock cycle will be shifted to the next stage of the register, thus allowing for the parallel output of the data stored in the register.The NLV74HC164ADTR2G is also designed to be used as a frequency divider. By using the clock signal from the register and feeding it back in as the data clock signal, the number of stages can be divided in two. This will slow down the transmission of data and allow for the frequency of the data to be divided or multiplied.Finally, the NLV74HC164ADTR2G is typically used as an interface between a data bus and external systems. The register can be used to speed up the communication between the data bus and the external systems by increasing the data rate.In summary, the NLV74HC164ADTR2G is a low-power, high-performance, 8-bit serial-in/parallel-out shift register. It has two clock inputs and operates either in a serial transmission mode or in a parallel transmission mode. This chip is used in many applications from motion control to communication control and from data acquisition to signal clocking. Furthermore, it can be easily used as a frequency divider or an interface between the data bus and external systems.
