Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the specified range of 4.75V to 5.25V to avoid damage to the device.

2. Input Voltages (V_IH, V_IL):

   • Input high voltage should be between 2.0V and 5.25V.
   • Input low voltage should be between 0V and 0.8V.

3. Output Voltages (V_OH, V_OL):

   • When sourcing current (I_O = -0.4 mA), the output high voltage should be between 2.4V and 5.0V.
   • When sinking current (I_O = 16 mA), the output low voltage should be between 0V and 0.4V.

4. Propagation Delay Time (t_pd):

   • The typical propagation delay time is 22 nanoseconds at 5V supply voltage and 25掳C ambient temperature.

5. Power Dissipation (P_D):

   • The maximum power dissipation is 600 milliwatts. Ensure proper heat dissipation if operating near this limit.

6. Operating Temperature (T_A):

   • The device can operate in temperatures ranging from -40掳C to 85掳C.

7. Storage Temperature (T_STG):

   • Store the device in temperatures ranging from -65掳C to 150掳C.

8. Handling:

   • Handle with care to avoid static discharge, which can damage the device.
   • Follow standard ESD (Electrostatic Discharge) precautions when handling the device.

9. Mounting:

   • Ensure proper soldering and mounting techniques to avoid mechanical stress on the device.

10. Testing:

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