Functional Features

  • The CD74ACT574M is a positive-edge-triggered D-type flip-flop with 8-bit storage capability.
  • It has an asynchronous Master Reset (MR) input, which when activated, clears all the flip-flop outputs to zero.
  • The Output Enable (OE) input allows for the tri-state output operation, enabling multiple devices to be connected in parallel.
  • This IC operates at high speed while consuming low power, making it suitable for various applications.

Advantages and Disadvantages

Advantages: - High-speed operation allows for quick data processing. - Low-power consumption helps in reducing energy usage. - Compact package size enables space-efficient designs. - Tri-state output feature facilitates easy integration with other devices.

Disadvantages: - Limited voltage supply range of 2V to 6V may restrict certain applications. - Maximum operating frequency of 100MHz may not meet the requirements of some high-speed systems.

Working Principles

The CD74ACT574M operates based on positive-edge-triggered D-type flip-flop functionality. When a rising edge is detected on the Clock (CLK) input, the data present at the Data Inputs (D0-D7) is transferred to the corresponding Q Outputs (Q0-Q7). The Master Reset (MR) input asynchronously clears all the outputs to zero when activated. The Output Enable (OE) input controls the tri-state output operation.

Detailed Application Field Plans

The CD74ACT574M can be used in various applications, including:

  1. Microprocessor Systems: Used for temporary storage of data during processing.
  2. Communication Systems: Facilitates data buffering and synchronization.
  3. Industrial Control Systems: Enables control signal storage and manipulation.
  4. Data Storage Systems: Used in memory modules for data storage and retrieval.
  5. Automotive Electronics: Supports various control functions in automotive systems.

Detailed and Complete Alternative Models

  1. SN74ACT574: Similar functionality with a different package (20-pin DIP).
  2. CD4013B: Dual D-type flip-flop with similar characteristics but different pin configuration.
  3. MC74HC574A: Octal D-type flip-flop with tri-state outputs, compatible with 5V supply voltage.
