HD74LS112P (74LS112)

Description: The HD74LS112P is a dual J-K flip-flop integrated circuit designed for use in digital logic applications. It features two independent J-K flip-flops, each capable of toggling its output based on the clock input (CLK), J (set) input, and K (reset) input signals. These flip-flops are edge-triggered and can operate in toggle mode (both J and K high), set mode (J high, K low), reset mode (J low, K high), or hold mode (both J and K low). The IC is commonly used for frequency division, counting, and sequential logic circuitry. Key Features:

• Dual J-K flip-flop IC
• Edge-triggered for synchronous operation
• Toggle, set, reset, and hold modes
• Wide operating voltage range: typically 4.75V to 5.25V
• Low power consumption
