Working Principles

The PI74FCT273ATQ is a D-type flip-flop that stores information on its eight data inputs (D0-D7) based on the clock pulse received at the CP pin. When the clock pulse transitions from low to high, the input data is latched and stored in the flip-flop. The stored data can then be accessed through the corresponding output pins (Q0-Q7). The output enable (OE) pin controls whether the stored data is presented at the outputs or not. The master reset (MR) pin resets the flip-flop to its initial state when activated.

Detailed Application Field Plans

The PI74FCT273ATQ is commonly used in various digital systems and applications, including:

1. Microprocessors: Used for temporary storage of data during processing.
2. Memory Systems: Employed as address latches or data buffers.
3. Communication Systems: Facilitates data synchronization and buffering.
4. Control Systems: Enables sequential logic operations and state storage.
5. Industrial Automation: Utilized in control circuits and data storage units.
