The HD74LV74FPEL is a dual D-type flip-flop belonging to the 74LV series of integrated circuits. Manufactured by Hitachi, it is designed for general-purpose storage and data transfer applications. The 'LV' designation indicates that it operates at a low voltage, making it suitable for modern low-power digital systems. Each flip-flop in the HD74LV74FPEL is edge-triggered, meaning that the output changes state only on the rising edge of the clock signal.
Applications
- Data storage
- Shift registers
- Frequency dividers
- Synchronization circuits
- Control circuits
Features
- Dual D-Type Flip-Flops: Contains two independent D-type flip-flops in a single package.
- Positive-Edge Triggered: Output changes state on the rising edge of the clock pulse.
- Set and Reset Inputs: Allows asynchronous setting and resetting of the flip-flop outputs.
- Low Voltage Operation: Operates from a 3.3V power supply (typically), compatible with modern logic levels.
- High-Speed Operation: Provides fast propagation delays for high-speed data transfer.
- Low Power Consumption: Characteristic of the LV (Low-voltage) CMOS family.
Benefits
- Simplified Circuit Design: Reduces component count in digital circuits.
- Versatile Functionality: Suitable for a wide range of storage and data transfer needs.
- Improved System Performance: High-speed operation reduces timing delays.
- Reduced Power Consumption: Low-voltage operation minimizes power dissipation, suitable for battery-powered devices.
- Easy Integration: Compatible with other CMOS logic devices.
Additional Details
The HD74LV74FPEL typically operates from a 3.3V power supply, but it can also operate at other voltages within the LV range (e.g., 2.7V to 3.6V). It's housed in a surface-mount package (likely SOIC or TSSOP). Each flip-flop has a D input, a clock input (CLK), a set input (SET), a reset input (RST), a Q output, and a Q-bar output. The SET and RST inputs are active-low and override the clock and D inputs. When SET is low, the Q output is set to high; when RST is low, the Q output is set to low.
