Functional Features

• Octal D-Type Flip-Flop: The SN74AC564PW consists of eight individual D-type flip-flops, each capable of storing a single bit of data.
• 3-State Outputs: The outputs of the flip-flops can be put into a high-impedance state using the OE (Output Enable) pin, allowing multiple devices to share a common bus.
• High-Speed Operation: With a propagation delay time of only 4.5ns, the SN74AC564PW is suitable for high-speed digital applications.
• Low Power Consumption: This IC is designed to operate at low power levels, making it energy-efficient.

Advantages and Disadvantages

Advantages: - High-performance flip-flop with fast operation - Low power consumption - 3-state outputs allow for efficient bus sharing

Disadvantages: - Limited voltage range (2V to 6V) - Relatively small package size may require careful handling during assembly

Working Principles

The SN74AC564PW operates based on the principles of digital logic. The D-type flip-flops store and transfer data based on clock signals. When the clock input (CLK) transitions from low to high, the data present at the D inputs is transferred to the corresponding Q outputs. The OE pin controls the output enable/disable function, allowing the outputs to be put into a high-impedance state when necessary.

Detailed Application Field Plans

The SN74AC564PW is commonly used in various digital systems, including:

1. Microprocessors and Microcontrollers
2. Communication Systems
3. Data Storage Devices
4. Industrial Control Systems
5. Automotive Electronics

In these applications, the IC is utilized for data storage, synchronization, and control purposes.
