The DM74AS74N is an integrated circuit (IC) component that belongs to the 74AS series of digital logic devices. It is a dual D flip-flop, offering two independent D flip-flops in a single package. Here are some key features and characteristics of the DM74AS74N:
1. Dual D flip-flop: The IC consists of two symmetrical D flip-flops that operate independently. Each flip-flop has separate D (data) inputs, clock inputs, preset inputs (PR), and clear inputs (CLR).
2. Edge-triggered design: The flip-flops are edge-triggered, meaning they only respond to the rising edge (positive transition) of the clock signal. This ensures precise synchronization and avoids any glitches that may occur during signal transitions.
3. Data inputs: Each flip-flop has a dedicated D input for data entry. The input is typically a digital signal (0 or 1) that gets stored within the flip-flop on the rising edge of the clock signal.
4. Clock inputs: The IC features separate clock inputs for each flip-flop. The clock signal determines when the data inputs are sampled and the flip-flops update their output states. It is crucial to synchronize the clock signal properly to avoid data loss or invalid states.
5. Preset and clear inputs: The DM74AS74N includes preset (PR) and clear (CLR) inputs for each flip-flop
