Functional Features

• The CLR pin allows clearing the flip-flop outputs.
• The D pin is used for data input.
• The CP pin triggers the flip-flop on the rising edge of the clock pulse.
• The Q0-Q7 pins represent the outputs of the eight flip-flops.
• The 74ACT174SCX operates with high speed and low power consumption.

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data processing. - Low-power consumption reduces energy requirements. - Compact SOIC package allows for space-saving integration.

Disadvantages: - Limited output drive capability may restrict use in certain applications. - The IC's operating temperature range may not be suitable for extreme environments.

Working Principles

The 74ACT174SCX is a positive-edge-triggered D-type flip-flop. It stores and outputs data based on the clock pulse input. When the clock pulse rises, the data at the D input is transferred to the corresponding Q output. The CLR pin can be used to clear all the flip-flop outputs simultaneously.

Detailed Application Field Plans

The 74ACT174SCX is commonly used in various digital systems and applications, including: - Data storage and retrieval systems - Register banks - Counters and frequency dividers - State machines and control circuits
