Functional Features

The 74ACT377SJ is designed to store and transfer data in sequential logic circuits. It operates on positive-edge triggered clock signals, allowing for synchronized data transfers. The IC incorporates a master-slave flip-flop configuration, ensuring reliable and accurate data storage.

Advantages and Disadvantages

Advantages: - High-speed operation - Low power consumption - Reliable data storage - Easy integration into existing circuit designs

Disadvantages: - Limited output current capacity - Sensitive to voltage fluctuations

Working Principles

The 74ACT377SJ functions as a latch, storing data based on the clock signal's rising edge. When the clock input (CP) receives a positive-edge trigger, the data inputs (D0-D7) are latched and transferred to the corresponding outputs (Q0-Q7). The enable input (G) controls the data transfer, while the clear input (CLR) resets the outputs to a predefined state.
