Functional Features

• Data storage and transfer: CD74HCT574M can store data on its flip-flops and transfer it to the output pins upon receiving a clock pulse.
• Output enable control: The OE pin allows for enabling or disabling the output, providing flexibility in data flow control.
• Master reset capability: The MR pin resets all flip-flops to their initial state when activated.

Advantages and Disadvantages

Advantages

• High-speed operation enables efficient data processing.
• Compatibility with TTL inputs allows for easy integration into existing circuits.
• Wide operating voltage range provides versatility in various electronic systems.
• Low power consumption contributes to energy efficiency.

Disadvantages

• Limited number of flip-flops may restrict the complexity of data storage and transfer operations.
• Sensitivity to electrostatic discharge (ESD) requires proper handling during installation and usage.

Working Principles

CD74HCT574M operates based on the principles of digital logic circuits. When a clock pulse is received, the data present at the input pins is latched onto the flip-flops. This stored data is then available at the output pins until the next clock pulse arrives. The output enable pin controls whether the stored data is accessible at the outputs or not. The master reset pin resets all flip-flops to their initial state when activated.
