Shift registers are digital circuits made up of several interconnected flip-flops. They are commonly used for storing and transferring data and have a variety of applications. The SN74LS165ADG4 is a type of shift register commonly used for a variety of logic operations. This article will discuss its application field and working principle.

Application Field

The SN74LS165ADG4 is a logic shift register used in logic circuits. It operates on an 8-bit binary data format and can be used to move data in or out of a circuit. The register is made up of eight separate shift registers. Each is independent of the other, but will follow the preceding shift register’s signal. It is commonly used for serial-to-parallel conversion and for parallel-to-serial conversion. It is also used for delay operations, signal conditioning, and data transfer operations.

The SN74LS165ADG4 is highly popular thanks to its simple design and ease of use. It is typically used in industrial, telecom, automobile, and medical applications. While the most common application is for serial-to-parallel conversion, it is also used in a variety of digital logic circuits for data transfer and signal treatments.

Working Principle

The SN74LS165ADG4 is a parallel-input serial-output semiconductor logic device. It is made up of eight independent shift registers. Each of the shift registers is made up of three flip-flops along with accompanying logic. Each flip-flop consists of a “Clock”Input, a “Data” Input and an “Output”.

When the “Clock”Input is enabled, the state of the “Data” Input is transferred to the “Output”. The output state is held until the next clock signal is given. The clock pulse is generated from an external source and is transferred from shift register to shift register. This daisy-chaining effect allows the SN74LS165ADG4 to move data in serial fashion.

The SN74LS165ADG4 also allows for parallel loading of 8-bit data. This feature provides for a more efficient data transfer. A parallel load is initiated by an input control signal. This signal transfers the data from eight corresponding data inputs to eight output latches of the shift registers. This in turn latches the output, holding it until the next parallel load.

The SN74LS165ADG4 also provides for serial loading of 8-bit data. This is accomplished by setting the data input and the parallel load pins high. This in turn enables the internal registers and allows the data from the inputs to be loaded in serial fashion into the corresponding output latch. Once the data has been clocked out, the parallel load pins are reset, disabling the internal registers.

The SN74LS165ADG4 is a highly versatile shift register with many applications. It is used in a variety of scenarios such as serial-to-parallel conversion, parallel-to-serial conversion, data transfer operations, and signal conditioning operations. Its simple design makes it a popular choice for digital logic circuits.
