Disadvantages

• Limited number of flip-flops per package (2 in this case)
• Requires an external clock signal for proper operation

Working Principles

The SN74ACT74NG4 is a dual D-Type Flip-Flop that operates on positive-edge triggered clock signals. The flip-flop has two inputs, D (data) and CLK (clock), which control the state of the outputs Q and Q̅. The asynchronous Clear (CLR) and Preset (PR) inputs allow immediate control over the flip-flop's state, regardless of the clock signal.

When the clock signal transitions from low to high (positive edge), the input data (D) is transferred to the output (Q) and its complement (Q̅). The Clear input resets the flip-flop to a known state, while the Preset input sets it to another known state. The complementary outputs make it suitable for various digital applications.

Detailed Application Field Plans

The SN74ACT74NG4 can be used in a wide range of digital systems and applications, including:

1. Sequential logic circuits
2. Data storage and retrieval systems
3. Counters and frequency dividers
4. State machines and control units
5. Clock synchronization circuits

Its high-speed operation and flexible state control make it suitable for applications requiring reliable and efficient data processing.
