Functional Features

The 74ACT11074NSR is a dual positive-edge-triggered D-type flip-flop. Its key functional features include:

• Dual Flip-Flops: The IC contains two independent flip-flops, allowing for simultaneous operation or separate usage.
• Positive-Edge Triggering: The flip-flops are triggered by the rising edge of the clock signal (CP).
• Data Storage: Each flip-flop can store a single bit of binary data (D1 and D2 inputs).
• Clear and Preset Functionality: The CLR and PR pins provide the ability to clear or preset the flip-flop outputs.
• Asynchronous Inputs: The CLR input allows for immediate clearing of the flip-flop, while the PR input enables presetting the flip-flop outputs.

Advantages and Disadvantages

Advantages

• High-speed operation enables efficient data transfer in time-critical applications.
• Low power consumption makes it suitable for battery-powered devices.
• Wide operating voltage range provides flexibility in various electronic systems.
• Good noise immunity ensures reliable performance in noisy environments.

Disadvantages

• Limited number of flip-flops per IC may require multiple ICs for larger-scale applications.
• Requires external clock signal for proper operation.

Working Principles

The 74ACT11074NSR operates based on the principles of sequential logic. When the clock signal (CP) experiences a rising edge, the flip-flops capture the data present at their respective D inputs and store it. The stored data remains unchanged until the next rising edge of the clock signal.

The CLR and PR inputs allow for additional control over the flip-flop outputs. When the CLR input is activated, the flip-flop outputs are immediately cleared to a low state. Conversely, activating the PR input sets the flip-flop outputs to a high state.

Application Field Plans

The 74ACT11074NSR can be applied in various digital electronic systems, including but not limited to:

1. Memory Units: Utilized as storage elements in memory units, allowing for data retention and retrieval.
2. Counters: Used as building blocks for counters, enabling the counting of events or signals.
3. Registers: Incorporated into register circuits for temporary data storage during processing.
