Functional Features

The CD74ACT273PWRE4 is an octal D-type flip-flop that operates on positive-edge clock pulses. It has a synchronous design, meaning the outputs change state simultaneously with the clock signal. The flip-flop can be cleared to a low state using the CLR input. It is designed for high-speed operation and low-power consumption, making it suitable for various digital applications.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Synchronous design ensures reliable output transitions - Wide operating voltage range

Disadvantages: - Limited number of flip-flops (8 in this case) - Not suitable for applications requiring a large number of sequential elements

Working Principles

The CD74ACT273PWRE4 operates based on the principles of sequential logic. It stores and outputs data based on clock pulses. When a positive-edge clock pulse is received, the data present at the inputs (D0-D7) is transferred to the corresponding outputs (Q0-Q7). The CLR input allows clearing the flip-flop to a low state, resetting the outputs. The flip-flop operates within a specified voltage range and has a propagation delay of 5.5ns.

Detailed Application Field Plans

The CD74ACT273PWRE4 can be used in various digital systems and applications, including but not limited to: - Microprocessors and microcontrollers - Data storage devices - Communication systems - Industrial control systems - Automotive electronics
