Instructions for Using 74HCT02D

1. Power Supply:

   • Connect the V_CC pin to a power supply between 2.0V and 6.0V.
   • Connect the GND pin to ground.

2. Input Connections:

   • Connect the input pins (1, 2, 9, 10) to either V_CC for a high logic level or GND for a low logic level.
   • Ensure that the input voltages do not exceed the specified V_IL and V_IH limits.

3. Output Connections:

   • The output pins (3, 11) will provide a low voltage (V_OL) when the inputs are high, and a high voltage (V_OH) when the inputs are low.
   • Ensure that the load connected to the output 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 state after the input changes. At V_CC=5V and TA=25°C, the typical delay is 18ns.

5. Operating Temperature:

   • The device is designed to operate within a temperature range of -40°C to 85°C.

6. Handling Precautions:

   • Handle the IC with care to avoid static damage.
   • Ensure proper heat dissipation if operating at higher temperatures or under heavy loads.

7. Storage:

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

8. Testing:

   • Use a multimeter or logic analyzer to verify the correct operation of the IC by checking the input and output voltages.
