Functional Features

• Dual JK flip-flop with individual clear and preset inputs
• Synchronous operation with a common clock input
• Outputs can be used as either true or complementary outputs
• High noise immunity due to Schmitt-trigger inputs
• Wide operating voltage range

Advantages and Disadvantages

Advantages: - Dual flip-flop in a single package saves board space - Clear and preset inputs provide flexibility in controlling the flip-flop state - Schmitt-trigger inputs enhance noise immunity

Disadvantages: - Limited maximum operating frequency compared to some modern ICs - DIP package may not be suitable for space-constrained applications

Working Principles

The SN74LS107AN is a dual JK flip-flop that operates based on the clock input and the J and K data inputs. The flip-flops are edge-triggered, meaning they change their output states only when a clock transition occurs. The clear and preset inputs allow for additional control over the flip-flop behavior.

Detailed Application Field Plans

The SN74LS107AN can be used in various digital logic applications, including but not limited to: - Counters and dividers - Frequency synthesizers - State machines - Data storage and retrieval systems
