Functional Features

The SN74ACT574NSRE4 is a D-type positive-edge-triggered flip-flop with 3-state outputs. It can store and transfer data on the rising edge of the clock pulse. The 3-state outputs allow multiple devices to be connected together without bus contention issues.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - 3-state outputs for bus sharing

Disadvantages: - Limited number of flip-flops (8 in this case) - Requires an external clock signal

Working Principles

The SN74ACT574NSRE4 operates based on the positive-edge-triggered flip-flop principle. When the clock pulse rises from low to high, the data present at the inputs (D0-D7) is transferred to the corresponding flip-flop outputs (Q0-Q6). The output enable (OE) pin controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74ACT574NSRE4 is commonly used in various digital systems where data storage and transfer are required. Some application fields include:

  1. Microprocessors and microcontrollers
  2. Communication systems
  3. Data acquisition systems
  4. Industrial automation
  5. Automotive electronics
