Functional Features

• Dual J-K flip-flop with independent clock and clear/preset inputs
• Edge-triggered operation on the positive transition of the clock pulse
• Asynchronous active LOW clear and preset inputs for individual flip-flops
• Direct overriding of the clock and data inputs for synchronous state changes
• High noise immunity due to Schmitt-trigger inputs
• Wide operating voltage range and temperature range

Advantages and Disadvantages

Advantages: - Dual flip-flop in a single package saves board space - Independent control inputs for each flip-flop allow flexible operation - Schmitt-trigger inputs provide improved noise immunity - Wide operating voltage and temperature range make it suitable for various applications

Disadvantages: - Limited number of flip-flops in a single package - Requires external components for complete circuit implementation - Not suitable for high-speed applications due to limited propagation delay

Working Principles

The SN74LS112ADR is a dual J-K flip-flop that operates based on the positive transition of the clock pulse. The J and K inputs determine the output state of the flip-flop, while the clear and preset inputs allow asynchronous clearing and setting of the flip-flop. The outputs Q1 and Q2 represent the current state of the flip-flop, while their complementary outputs Q1̅ and Q2̅ provide the inverse states.

Detailed Application Field Plans

The SN74LS112ADR can be used in various applications, including: - Counters and dividers - Shift registers - Frequency division circuits - State machines - Data storage and retrieval systems
