Logic - Shift Registers

The SN74HC164DRG3 is a type of series static synchronous 8-bit shift-register. It can be used for serial-to-parallel conversions, data buffering capabilities and for various other purposes and applications.

Application Field

The SN74HC164DRG3 shift register is best suited for applications that call for either a serial-to parallel data converters, data buffering, scanning arrays or where shift register capability is required. It can also be used as a serial-in/serial-out shift register or as a serial-in/parallel-out shift register.

For example, the SN74HC164DRG3 shift register can be used to control multiple LEDs or uses in the LCD screen where limited inputs require additional outputs. Additionally, this type of shift register can be used as a universal shift register, both as a serial-in/serial-out or serial-in/parallel-out device.

Working Principle

The SN74HC164DRG3 shift register works by taking a serial digital input and outputting 8 parallel outputs. By placing 8 flip-flops in series, and joining their serial output to the the serial input, it creates the shift-register. The propagation delay of the SN74HC164DRG3 shift register is typically 6.5 to 10ns. The flip-flop inputs change simultaneously and the outputs change on the negative transition of the clock.

The shift register works on a single digital input clock cycle. All bits of data will be shifted simultaneously by using the each digital input cycle. For example, when the first clock pulse is applied, the eight-bit register arranges the data in sequence, with the eighth bit shifted out first, followed by the seventh bit and so on. This will continue until all data has been shifted out.

The SN74HC164DRG3 is also equipped with an asynchronous clear/reset input that is connected to ground. This make it possible to reset all the flip-flops at the same time, hence reducing the time required in order to reset the register. Furthermore, it also has an asynchronous reset clock enable input which is used to disable the clock input for future applications.

Conclusion

The SN74HC164DRG3 shift register is an ideal choice for any application that requires serial-to-parallel conversion, data buffering or scanning array needs. Its asynchronous reset inputs and clock enable inputs make this type of shift register a top choice for any application or project. With its simple operation and wide range of available applications the SN74HC164DRG3 is a reliable and efficient choice that is sure to satisfy any user\'s need.
