Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 1.5V to 6.5V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Apply input signals that are within the specified input voltage levels (V_IL and V_IH).
   • Avoid exceeding the maximum input voltage, which should not exceed V_CC.

3. Output Signals:

   • The output low voltage (V_OL) should be no higher than 0.25V when sourcing up to 16mA.
   • The output high voltage (V_OH) should be at least V_CC - 0.25V when sinking up to -4mA.

4. Current Handling:

   • Ensure that the output current does not exceed the specified limits to avoid damage to the device.
   • The input leakage current and output leakage current should be kept within ±1μA.

5. Timing Considerations:

   • The propagation delay time (t_pd) is typically 9ns under standard conditions. Adjust your timing requirements accordingly.

6. Thermal Management:

   • Monitor the power dissipation (P_D) to ensure it does not exceed 100mW to prevent overheating.
   • Use appropriate heat sinks or cooling methods if necessary.

7. Storage and Handling:

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

8. Testing and Troubleshooting:

   • Use a multimeter to verify the supply voltage and output voltages.
   • Check for any short circuits or open circuits in the connections.
   • Refer to the datasheet for more detailed testing procedures and troubleshooting tips.
