Instructions for Using 74HC03D:

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:

   • Ensure that input signals are within the valid range: 0.0V to 0.8V for low logic level and 2.0V to V_CC for high logic level.
   • Avoid leaving inputs floating; use pull-up or pull-down resistors if necessary.

3. Output Signals:

   • The output can drive up to 4 mA of current when low and sink up to 0.4 mA when high.
   • Ensure that the load connected to the output is within these limits to avoid damage.

4. Propagation Delay:

   • The propagation delay time is typically 18 ns at V_CC = 4.5V. This value may vary with different supply voltages and temperatures.

5. Power Dissipation:

   • The maximum power dissipation is 100 mW. Ensure proper heat dissipation if operating near this limit.

6. Operating Temperature:

   • The device is designed to operate over a temperature range from -40°C to +85°C.

7. Handling Precautions:

   • Handle the IC with care to avoid static discharge which can damage the internal components.
   • Use appropriate ESD protection measures during handling and installation.

8. Storage:

   • Store the IC in a dry, cool place to prevent moisture damage.

By following these instructions, you can ensure reliable operation of the 74HC03D quad 2-input NAND gate IC.
