Functional Features

• Data Storage: The 74ACT273SCX can store data on its inputs (D0-D3) and retain it until a clock signal is received.
• Clock Triggered Operation: The flip-flop updates its output based on the input data only when a rising edge is detected on the CLK pin.
• Output Enable Control: The /OE (Output Enable) pin allows the user to enable or disable the outputs, providing flexibility in data retrieval.

Advantages and Disadvantages

Advantages

• High-speed operation enables efficient data processing.
• Low power consumption contributes to energy efficiency.
• Wide operating voltage range enhances compatibility with different systems.
• Compact SOIC package facilitates integration into various electronic devices.

Disadvantages

• Limited storage capacity: The 74ACT273SCX can store only one bit of information at a time.
• Requires an external clock signal for proper operation.

Working Principles

The 74ACT273SCX operates based on the principles of sequential logic. When the clock signal rises, the input data is latched and stored in the flip-flop. The stored data remains unchanged until the next clock cycle triggers an update. The output can be enabled or disabled using the /OE pin.
