Instructions for Using the 74HCT174

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (2.0V to 6.0V).
   • Connect the GND pin to the ground.

2. Input Signals:

   • Apply the data input signal (D) to the appropriate D pin.
   • Apply the clock signal (CLK) to the CLK pin.
   • Use the clear (CLR) and preset (PR) pins to set or reset the flip-flop. These are active low, so apply a low signal to activate them.

3. Output Signals:

   • The Q output will follow the state of the D input on the rising edge of the clock signal (for positive-edge triggered flip-flops).
   • The Q? output is the complement of the Q output.

4. Propagation Delay:

   • Ensure that the propagation delay time (t_pd) is considered in your timing calculations to avoid race conditions.

5. Power Consumption:

   • Be aware of the power consumption, especially at higher frequencies, to ensure proper heat dissipation and avoid overheating.

6. Temperature Range:

   • Operate the device within the specified temperature range to ensure reliable performance.

7. Storage and Handling:

   • Store the device in a dry, cool place within the storage temperature range to prevent damage.

By following these instructions and parameters, you can effectively use the 74HCT174 D-type flip-flop in your circuits.
