Working Principles

The CD74HC173PWRE4 is a 4-bit register that stores and retrieves digital data. It operates based on clock pulses received at the CP pin. When a clock pulse is detected, the data inputs (D0-D3) are latched and stored in the corresponding flip-flops within the register. The stored data can then be accessed through the output pins (Q0-Q3). The asynchronous clear input (CLR) allows for resetting the register to a known state, regardless of the clock signal.

Detailed Application Field Plans

The CD74HC173PWRE4 can be used in various applications that require data storage and retrieval. Some potential application fields include:

1. Microcontrollers: Used as temporary storage for intermediate results or status flags.
2. Communication Systems: Used for buffering and storing incoming data packets.
3. Digital Signal Processing: Used for storing coefficients or intermediate results in signal processing algorithms.
4. Data Logging: Used for storing sensor readings or event timestamps in data logging systems.
