Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V.
   • Connect the ground (GND) pin to the system ground.

2. Input Signals:

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

3. Output Signals:

   • The output signals will be driven to either V_OL or V_OH depending on the input state.
   • Ensure the load connected to the outputs does not exceed the maximum current ratings.

4. Propagation Delay:

   • The propagation delay times (t_PLH and t_PHL) are critical for timing considerations in your circuit design.
   • These values are typically given for a specific temperature and supply voltage.

5. Temperature Considerations:

   • The device is designed to operate within the temperature range of -40掳C to 85掳C.
   • Store the device within the storage temperature range of -65掳C to 150掳C.

6. Handling Precautions:

   • Handle the device with care to avoid static damage.
   • Use proper ESD protection when handling and soldering the device.

7. Layout and PCB Design:

   • Keep the power and ground lines short and wide to minimize noise and improve performance.
   • Use decoupling capacitors (typically 0.1渭F) close to the power pins to filter out high-frequency noise.

8. Testing and Verification:

   • Test the device under typical operating conditions to ensure it meets the specified parameters.
   • Verify the functionality with a known good test setup before integrating into a larger system.
