Instructions for Using MC74ACT02N

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 5.5V.
   • Connect the ground (GND) pin to a stable reference point.

2. Input Signals:

   • For a low input (V_IL), the voltage should be less than 0.8V when V_CC is between 4.5V and 5.5V.
   • For a high input (V_IH), the voltage should be greater than 2.0V when V_CC is between 4.5V and 5.5V.

3. Output Signals:

   • The output low voltage (V_OL) should not exceed 0.4V when sinking 16mA and V_CC is between 4.5V and 5.5V.
   • The output high voltage (V_OH) should be at least 2.4V when sourcing -4mA and V_CC is between 4.5V and 5.5V.

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 6ns at V_CC = 5V and T_A = 25°C.

5. Power Dissipation:

   • The maximum power dissipation (P_D) is 360mW under continuous operation.

6. Handling Precautions:

   • Avoid exposing the device to static electricity as it can cause damage.
   • Ensure proper heat dissipation if operating near the maximum power dissipation limit.

7. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Follow ESD (Electrostatic Discharge) precautions during handling and installation.

8. Soldering:

   • Use a soldering iron with a temperature not exceeding 300°C.
   • Avoid excessive soldering time to prevent thermal damage to the device.

By following these guidelines, you can ensure reliable and efficient operation of the MC74ACT02N.
