Instructions for Use:

1. Supply Voltage:

   • Ensure the supply voltage (V_CC) is within the specified range of 4.5V to 5.5V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Input signals should be within the valid input voltage levels (V_IL and V_IH).
   • Avoid floating inputs; use pull-up or pull-down resistors as necessary.

3. Output Signals:

   • Ensure that the load connected to the output does not exceed the maximum current ratings.
   • The output high level voltage (V_OH) and output low level voltage (V_OL) should be within the specified limits.

4. Propagation Delay:

   • Consider the propagation delay time (t_pd) when designing timing-sensitive circuits.

5. Power Dissipation:

   • Ensure that the total power dissipation (P_D) does not exceed 350 mW to avoid overheating.

6. Temperature Range:

   • Operate the device within the specified ambient temperature range (-40°C to 85°C).
   • Store the device within the storage temperature range (-65°C to 150°C).

7. Handling:

   • Handle the device with care to avoid static damage. Use proper ESD protection measures.
   • Follow recommended soldering and mounting procedures to ensure reliable operation.
