Functional Features

The CD74ACT273MG4 is a high-speed, low-power consumption D-type positive-edge-triggered flip-flop. It can store and transfer data in various applications. The key functional features include:

• Positive-edge triggering of the clock input
• Asynchronous active LOW clear input to reset the flip-flop
• Eight data inputs for storing data bits
• Eight corresponding output pins for retrieving stored data
• Wide operating voltage range for flexibility
• High output drive capability for driving external loads

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data storage and retrieval - Low-power consumption minimizes energy usage - Compact package size enables space-saving designs - Wide operating voltage range provides versatility in different applications

Disadvantages: - Limited number of flip-flop elements per IC - Not suitable for applications requiring negative-edge triggering

Working Principles

The CD74ACT273MG4 operates based on the positive-edge-triggered D-type flip-flop principle. When a positive clock pulse is applied to the CP pin, the data inputs (D0-D7) are latched and stored in their corresponding flip-flop bits. The stored data can then be retrieved from the output pins (Q0-Q7). The clear input (CLR) allows for asynchronous resetting of the flip-flop, clearing all stored data.

Detailed Application Field Plans

The CD74ACT273MG4 can be used in various applications that require data storage and retrieval, such as:

1. Microcontrollers and microprocessors
2. Data communication systems
3. Memory modules
4. Digital signal processing
5. Industrial automation
