Instructions

1. Power Supply:

   • Connect the V_CC pin to the positive supply voltage (2.0V to 6.0V).
   • Connect the GND pin to the ground (0V).

2. Input Signals:

   • Apply input signals to the input pins (1, 2, 4, 5, 9, 13).
   • Ensure that the input voltages are within the specified range (V_IL to V_IH).

3. Output Signals:

   • The output signals will be inverted from the input signals.
   • The output pins (2, 4, 6, 8, 10, 12) will provide the inverted logic levels.

4. Propagation Delay:

   • The time delay between the input and output transitions (t_PLH and t_PHL) should be considered in timing-sensitive applications.

5. Temperature Considerations:

   • The device is designed to operate within the temperature range of -40掳C to 85掳C.

6. Handling:

   • Handle the IC with care to avoid static damage.
   • Use appropriate ESD protection when handling the device.

7. Pin Configuration:

   • Refer to the pinout diagram for correct pin connections.
   • Unused inputs should be tied to V_CC or GND to prevent floating.
