Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 4.5V to 5.5V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Apply input signals (D, CP, CLR, PR) with voltages that meet the input high (V_IH) and input low (V_IL) requirements.
   • Ensure that input signals are clean and free from noise to avoid false triggering.

3. Output Signals:

   • The output signals (Q, Q?) will be driven to either V_OH or V_OL depending on the state of the flip-flop.
   • Ensure that the load connected to the outputs does not exceed the maximum current ratings.

4. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for the output to change after a valid clock edge. This is typically between 5 and 9 nanoseconds at room temperature (25°C).

5. Temperature Range:

   • The device is designed to operate within the temperature range of -40°C to 85°C. Ensure that the operating environment does not exceed these limits to avoid damage or unreliable operation.

6. Power Dissipation:

   • The maximum power dissipation (P_D) is 100 mW. Ensure that the device is not subjected to excessive power dissipation, which can cause overheating and potential failure.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Use appropriate ESD protection measures when handling and soldering the device.

8. Schematic Example:

   • A typical application circuit for the 74F74PC D-type flip-flop might include pull-up resistors on the inputs and decoupling capacitors near the power pins to ensure stable operation.

By following these guidelines, you can ensure reliable and efficient operation of the 74F74PC D-type flip-flop in your circuit design.
