Instructions for Use:

1. Power Supply:

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

2. Input Signals:

   • Apply input signals that meet the input voltage levels (V_IH and V_IL).
   • Ensure input currents do not exceed the maximum ratings.

3. Output Signals:

   • The output voltages (V_OH and V_OL) will be within the specified ranges.
   • Do not exceed the maximum output current ratings (I_OH and I_OL).

4. Propagation Delay:

   • The propagation delay time (t_pd) is critical for timing considerations. It is typically 13ns at 5V and 25掳C but can vary between 13ns and 35ns.

5. Temperature Considerations:

   • Operate the device within the specified temperature range (T_A) to ensure reliable performance.
   • Store the device within the storage temperature range (T_STG) to prevent damage.

6. Power Dissipation:

   • Ensure the power dissipation (P_D) does not exceed 100mW to avoid overheating and potential damage.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow proper soldering techniques to ensure good electrical connections and avoid thermal stress.
