Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the operating range of 2.0V to 6.0V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Input signals should be within the valid input voltage levels:
     • Low level (V_IL): 0V to 1.5V
     • High level (V_IH): 3.5V to V_CC
   • Avoid exceeding these levels to prevent damage to the device.

3. Output Signals:

   • The output low voltage (V_OL) should not exceed 0.4V when sinking 4mA.
   • The output high voltage (V_OH) should be at least 4.4V when sourcing -0.4mA.

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically between 14ns and 22ns at a supply voltage of 4.5V to 5.5V and an input frequency of 10MHz.

5. Thermal Management:

   • Ensure the device does not exceed the maximum power dissipation (P_D) of 100mW to avoid overheating.
   • Operate the device within the commercial temperature range of 0°C to 70°C.
   • Store the device within the storage temperature range of -40°C to 125°C.

6. Handling and Storage:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Store the device in a dry, cool place to prevent moisture damage.

7. Circuit Design:

   • Use appropriate decoupling capacitors (e.g., 0.1μF) close to the power pins to filter out noise and ensure stable operation.
   • Ensure all unused inputs are tied to a known state (either V_CC or GND) to prevent floating inputs, which can cause unpredictable behavior.

8. Testing and Debugging:

   • Verify the supply voltage and ground connections before applying any input signals.
   • Use an oscilloscope to monitor the input and output waveforms to ensure proper signal integrity.
   • If the device does not function as expected, check for any shorts or open circuits in the power and signal lines.
