Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 4.5 V to 5.5 V.
   • Do not exceed the maximum supply voltage to avoid damaging the device.

2. Input Voltage (V_I):

   • For a valid low input, the voltage should be between 0 V and 0.8 V.
   • For a valid high input, the voltage should be between 2.0 V and V_CC.

3. Output Voltage:

   • When the output is high (V_OH), it should be at least 2.4 V and can go up to V_CC - 0.1 V.
   • When the output is low (V_OL), it should be no more than 0.4 V.

4. Leakage Current:

   • Ensure that the input and output leakage currents do not exceed ±1 μA to maintain proper operation.

5. Propagation Delay Time (t_pd):

   • The propagation delay time is typically 12 ns under standard conditions (V_CC = 5 V, V_I = 2.5 V to 0.8 V or 2.0 V).

6. Power Dissipation (P_D):

   • The maximum power dissipation is 150 mW. Ensure adequate heat dissipation to prevent overheating.

7. Operating Temperature:

   • For commercial use, the operating temperature range is 0°C to 70°C.
   • For industrial use, the operating temperature range is -40°C to 85°C.

8. Handling:

   • Handle the device with care to avoid static damage.
   • Follow proper ESD (Electrostatic Discharge) precautions when handling the device.

9. Mounting:

   • Ensure proper mounting and soldering techniques to avoid mechanical stress on the device.
   • Use a suitable PCB layout to minimize noise and interference.

10. Storage:

    • Store the device in a dry, cool place to prevent moisture damage.
    • Follow recommended storage conditions to ensure long-term reliability.
