Instructions for Using the 74LV74 D Flip-Flop

1. Power Supply:

   • Connect the VCC pin to a power supply between 1.65V and 5.5V.
   • Ensure GND is connected to the ground.

2. Clock Input (CP):

   • Apply clock signals to the CP pin. The flip-flop will capture the data at the positive or negative edge of the clock signal depending on the configuration.

3. Data Input (D):

   • Connect the input signal you want to latch to the D pin. Ensure that the voltage levels are within the valid range for logic high and low as defined by VIH and VIL.

4. Set (SET) and Reset (RESET) Inputs:

   • If used, apply logic high to SET or RESET to set or reset the output regardless of the clock state. These inputs are active high.

5. Output (Q and Q?):

   • The Q pin provides the non-inverted output of the flip-flop.
   • The Q? pin provides the inverted output of the flip-flop.

6. Propagation Delay:

   • Be aware of the propagation delay times to ensure timing requirements are met in your design. Adjustments might be necessary based on the specific application.

7. Operating Temperature Range:

   • Ensure the device operates within its specified temperature range to maintain reliable performance.

8. Handling:

   • Handle with care to avoid damage from electrostatic discharge (ESD). Use proper ESD protection practices when handling and soldering the component.
