Instructions for SN74LS74N

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.75V to 5.25V to avoid damage and ensure proper operation.

2. Input Levels:

   • For a valid high input, the voltage should be at least 2.0V.
   • For a valid low input, the voltage should not exceed 0.8V.

3. Output Levels:

   • When the output is high, it should provide at least 2.7V when sourcing up to 0.4mA.
   • When the output is low, it should not exceed 0.5V when sinking up to 16mA.

4. Propagation Delay:

   • The typical propagation delay time (tpd) is 22ns under standard conditions with Vcc at 5V.

5. Power Dissipation:

   • Keep the power dissipation per package below 100mW to prevent overheating and potential damage.

6. Handling:

   • Handle the device with care to avoid static damage. Use appropriate ESD protection measures.

7. Application Notes:

   • This device is suitable for applications requiring D-type flip-flops with preset and clear functions. It can be used in various digital circuits for data storage and signal processing.
