Logic - Shift Registers are devices used in integrated circuits that store binary digits, also known as bits, and move these bits to either the left or right by one or more steps. The 74LV164DB,112 is a device that is an example of such a type of register. This device is a Logic - Shift Register that comes in a 14-pin small outline integrated circuit (SOIC) package and is an 8-bit parallel-in, serial out shift register. The chip is capable of operating over the ambient temperature range of - 40°C to +85°C.

The purpose of the shift register is to store 8 bits of data. The data comes in parallel, meaning each bit is stored in a separate location and that the entire 8 bits of data can be written simultaneously. The 74LV164DB,112 then outputs this data one bit at a time, in serial format. This data can be continuously shifted out or it can be outputted only once and then the shift register can then shift the same data over and over again. This means that the 74LV164DB,112 can be used to extend the output of a single device to a larger number of bits.

The 74LV164DB,112 contains an 8-bit flip-flop register that is capable of either loading data into or shifting the stored data. The loading operation allows the user to input a parallel 8-bit data. This data is then stored into the register. Conversely, the switching operation enables the 8-bit data to be output one bit at a time. The storage of data in the register is enabled by a latch enable signal, LE. When LE is at logic \'1\', the data present at the 8-bit input lines is stored into the register. This data is then outputted one bit at a time starting with the least significant bit when the switching signal, CLK, is at a logic \'1\'. The CLK signal is then used to output each bit of the data stream one bit at a time. The serial output of the 74LV164DB,112 is accessed from pin 3 on the SOIC package.

The 74LV164DB,112 are commonly used for data transmission, memory locations, and shift registers. It can be used in a multitude of applications, from counting and timing operations, to implementing memory locations and shift registers, to using it as an asynchronous parallel-out serial-in port for microprocessor data transmission. Due to its 8-bit data bus that allows a simultaneous write and read operation, as well as its capacity to store and shift data, the 74LV164DB,112 can be used to reduce the number of wires and leads required in applications that involve multiple devices.

The 74LV164DB,112 can also be used to simplify system troubleshooting. By transferring data to and from the register, it can be used to monitor the status of multiple bits at once. This gives the operator an easy way to identify trouble spots in the circuit.

Apart from simplifying system troubleshooting and reducing the number of leads required in applications, the 74LV164DB,112 can also be used to reduce electromagnetic interference (EMI) in systems that involve large data transfer rates. The register can be used to store and retrieve data at a faster rate than usual, thus reducing the time that the data is broadcasted, and hence reducing EMI.

In summary, the 74LV164DB,112 is an 8-bit Logic - Shift Register that can store and shift 8 bits of data in parallel or in serial format. The device is commonly used for data transmission, memory location, and shift registers. It is also used to reduce the number of wires and leads required in applications, simplify system troubleshooting, and reduce EMI in systems with large data transfer rates.
