SN74LV164ARGYR Application Field and Working Principle

The SN74LV164ARGYR is a lowvoltage parallel-in/serial-out 8-bit shift register. It is part of the LV164A family which includes both 8-bit (SN74LV164A) and 10-bit (SN54LV165A) devices. The SN74LV164ARGYR is one of the most commonly used types of logic-shift registers in industries.

Logic-shift registers are used to manipulate a binary waveform in a continuous sequence of operations. The waveform can be converted into a digital form that can be manipulated and shifted across multiple stages of operations. This can greatly reduce the number of clock cycles needed for a given operation and is used in data communication, timing, control, pattern recognition, and consumer electronics.

Application Field of SN74LV164ARGYR

Logic-shift registers are widely used in a variety of different applications. The SN74LV164ARGYR is typically used in addressing memory, selecting between different sources of data, and in clock-controlled circuit switching. It can also be used to convert parallel data into serial data on a single data line. The SN74LV164ARGYR is also used as a Universal Synchronous/Asynchronous Receiver and Transmitter (USART), which is a type of serial communication device.

The SN74LV164ARGYR is also used in motor control, digital-to-analog conversion, and optical communication systems. It can also be used in digital audio and video systems for decoding multiplexed signals, and for selecting between different sources of data on a single line. The SN74LV164ARGYR can also be used to encode digital data for transmission over a network.

Working Principle of SN74LV164ARGYR

The SN74LV164ARGYR is an 8-bit shift register, meaning that it contains eight separate stages of registers which can be set to different logic levels. The inputs are parallel and consist of eight separate input lines, whereas the output is shifted serially. The SN74LV164ARGYR shift register starts at stage 0 and works its way through the other seven stages. The logic of each shift register is toggled each time the clock edge is detected.

The data is loaded into the SN74LV164ARGYR shift register stages on the positive edge of the clock. The output of the register is shifted through each stage on the negative edge of the clock. When the data is shifted through the last stage of the register, it is output on the serial output line (Q7). By using the Mode and Clock Enable pins, the SN74LV164ARGYR can be set up to have a serial or parallel input, or to operate in a single-clock or multiple-clock mode.

The SN74LV164ARGYR also has an over-voltage protection circuit built-in to protect the chip from any over-voltage conditions. The chip is built using advanced CMOS technology and has tight timing requirements so that the data is loaded and shifted correctly.

Conclusion

The SN74LV164ARGYR is a type of logic-shift register used for a variety of different applications. It is responsible for manipulating binary waveforms in a continuous sequence of operations, allowing for data to be manipulated and shifted across multiple stages. The chip has a number of features such as over-voltage protection and tight timing requirements built-in. The SN74LV164ARGYR is commonly used in addressing memory, selecting different sources of data, clock-controlled circuit switching, as a USART, and in digital audio and video systems.
