74HCT595BQ-Q100 11 Application Field and Working Principle

The 74HCT595BQ-Q100 is a Logic-Shift Register, developed by the NXP semiconductor manufacturer. It is a nine-bit register composed of two separate 4-bit register banks. Each 4-bit register contains two flip-flops, and each flip-flop can be independently addressed and written, so that two data transitions can occur in parallel. The 74HCT595BQ-Q100 has high-speed logic, a low-power CMOS, and gives excellent high-speed performance in low-voltage applications. It also has various operational modes which are user-selectable by programming the input mode (IR[3:0]).

Application Field

The 74HCT595BQ-Q100 is broadly used in computers, communications, consumer electronics, industrial automation, automotive applications, audio-visual systems and other fields. In particular, the wide range of applications for the 74HCT595BQ-Q100 include both low-speed and high-speed serial communications for memory and peripheral devices; communication between general purpose microprocessors and peripherals; serial I/O used as interface between host and microcontroller; shift clock and data registers used as interface between communications peripherals and microprocessor; shift registers used to interface address and control registers in memories, memories and peripheral devices.

Working Principle

The 74HCT595BQ-Q100 has a serial-input, serial-output (SISO), which is initially loaded with user-defined data via the serial input connection. The data are synchronised with the incoming clock so that the register can be read and placed into a given position as required. The output stage of the 74HCT595BQ-Q100 is also driven by a clock signal that is synchronised with the serial data flow. The internal logic of the register circuit controls the output points, allowing data to flow from one register to the next in a predetermined or programmed order. The register can be programmed to code data both in serial and parallel manner.

Conclusion

The 74HCT595BQ-Q100 is a Logic-Shift Register, developed by the NXP semiconductor manufacturer. It has high-speed logic, a low-power CMOS, and a wide range of applications. It is used in laptops, communications systems, consumer electronics, industrial automation, automotive applications, and audio-visual systems. It uses a SISO, with which data are initially loaded with user-defined data via the serial input connection; the output stage of the 74HCT595BQ-Q100 is driven by a clock signal that is synchronised with the serial data flow.
