Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the specified range of 4.75V to 5.25V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Apply logic levels (0V or 5V) to the input pins.
   • Ensure input signals do not exceed the supply voltage or go below ground level to avoid damage.

3. Output Signals:

   • The output pins can source up to 16mA and sink up to 24mA.
   • Ensure the load connected to the output does not exceed these current limits.

4. Propagation Delay:

   • The propagation delay time (tpd) is typically 5ns with a maximum of 9ns. This should be considered in timing-sensitive applications.

5. Temperature Considerations:

   • The device operates reliably within the temperature range of -40°C to 85°C.
   • Store the device in a temperature range of -65°C to 150°C when not in use.

6. Power Dissipation:

   • Ensure the total power dissipation does not exceed 330mW to prevent overheating and potential damage.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage sensitive components.
   • Use proper anti-static precautions when handling and soldering the device.

8. Mounting:

   • Ensure the device is securely mounted on the PCB to avoid mechanical stress.
   • Follow recommended soldering profiles to ensure reliable connections.
