The N74F109D,623 is an IC (integrated circuit) component manufactured by NXP Semiconductors. It is a dual positive-edge-triggered D-type flip-flop with preset and clear capabilities. Here are some key features of the N74F109D,623:
1. Dual Flip-Flop: The IC contains two separate D-type flip-flops, which can be individually controlled and operated.
2. Positive-Edge Triggered: The flip-flops in the N74F109D,623 are triggered on the positive edge of the clock signal. This allows for synchronous operation and precise timing.
3. Preset and Clear Functionality: The IC includes preset (PRE) and clear (CLR) inputs for each flip-flop. These inputs allow the user to set or reset the flip-flop outputs independently.
4. Complementary Outputs: The outputs (Q and Q?) of each flip-flop are complementary to each other. When one output is high, the other is low, and vice versa.
5. Schmitt Trigger Inputs: The IC features Schmitt trigger inputs, which provide hysteresis and improve noise tolerance. This helps in reducing the chances of false triggering due to signal fluctuations or noise.
6. Buffered Inputs: The inputs (D, PRE, CLR) are buffered, ensuring improved signal integrity and reducing the chances of loading effects on the connected circuitry
