Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 5.5V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Input signals should be within the specified input voltage levels (V_IL and V_IH).
   • Avoid applying voltages outside the supply voltage range to the input pins.

3. Output Signals:

   • The output signals will be within the specified output voltage levels (V_OL and V_OH).
   • Ensure that the load connected to the output does not exceed the maximum power dissipation (P_D).

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 3.5ns. This value can vary depending on the specific operating conditions.

5. Temperature Considerations:

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

6. Handling and Storage:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Store the device in a dry environment to prevent moisture-related issues.

7. Mounting and Soldering:

   • Follow recommended soldering profiles to ensure reliable connections.
   • Avoid excessive heat during soldering to prevent damage to the device.

8. Testing:

   • Test the device under the specified operating conditions to ensure proper functionality.
   • Use appropriate test equipment and methods to avoid damaging the device.
