Instructions for Using BU4011BF:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 4.5V to 5.5V.
   • Use a stable power source to avoid fluctuations that can affect performance.

2. Input Signals:

   • For a high input signal, ensure the voltage (VIH) is at least 2.0V and up to Vcc - 0.5V.
   • For a low input signal, ensure the voltage (VIL) is between 0V and 0.8V.

3. Output Signals:

   • The output high voltage (VOH) should be at least 2.4V and can go up to Vcc - 0.5V when the output current (IOH) is -8mA.
   • The output low voltage (VOL) should be between 0V and 0.6V when the output current (IOL) is 8mA.

4. Propagation Delay:

   • The propagation delay time (tpd) is typically 12ns and can be as high as 25ns under standard conditions (Vcc=5V, TA=25°C).

5. Power Consumption:

   • The typical power consumption (ICC) is 1μA and can go up to 10μA with no load at Vcc=5V.

6. Temperature Considerations:

   • The operating temperature (TA) should be between -40°C and 85°C.
   • The storage temperature (Tstg) should be between -65°C and 150°C.

7. Handling:

   • Handle the BU4011BF with care to avoid static discharge which can damage the component.
   • Follow proper soldering techniques to ensure reliable connections.

8. Applications:

   • Suitable for digital logic circuits, particularly where low power consumption and fast switching times are required.

By following these guidelines, you can ensure optimal performance and reliability of the BU4011BF in your applications.
