Instructions for Use:

1. Power Supply:

   • Connect the V_CC pin to a 5V power supply.
   • Connect the GND pin to ground.

2. Input Signals:

   • Ensure that input signals are within the specified voltage range for V_IH and V_IL.
   • Avoid applying voltages outside the recommended range to prevent damage to the device.

3. Output Loads:

   • Ensure that output loads do not exceed the maximum output current ratings (I_OH and I_OL).
   • Use appropriate pull-up or pull-down resistors if necessary to ensure proper logic levels.

4. Propagation Delay:

   • Account for the propagation delay time (t_pd) when designing circuits to ensure timing requirements are met.

5. Temperature Considerations:

   • Operate the device within the specified temperature range (T_A) to avoid thermal stress and potential failure.

6. Storage and Handling:

   • Store the device in a dry, static-free environment.
   • Handle with care to avoid mechanical damage and electrostatic discharge (ESD).

7. Soldering:

   • Use a soldering iron with a temperature not exceeding 300掳C.
   • Solder each pin quickly to avoid thermal stress on the device.

8. Testing:

   • Test the device under typical operating conditions to ensure it meets the specified performance parameters.
