Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 4.75V to 5.25V to avoid damage to the device.

2. Input Voltage Levels:

   • Input signals should be within the specified ranges: V_IL (0.0V to 0.8V) for low logic level and V_IH (2.0V to 5.0V) for high logic level.

3. Output Voltage Levels:

   • When driving a load, ensure that the output low voltage (V_OL) does not exceed 0.5V at 16 mA and the output high voltage (V_OH) is at least 2.4V at -0.4 mA.

4. Propagation Delay (t_pd):

   • The typical propagation delay time is 23 nanoseconds. This is crucial for timing considerations in your circuit design.

5. Power Dissipation (P_D):

   • The maximum power dissipation is 500 mW. Ensure proper heat management if operating near this limit.

6. Operating Temperature (T_A):

   • The device can operate within the temperature range of -40°C to 85°C. Ensure the ambient temperature stays within these limits to maintain reliable operation.

7. Handling and Storage:

   • Handle the device with care to avoid static damage. Store in a dry, cool place when not in use.

8. Circuit Design:

   • Use appropriate decoupling capacitors near 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 lead to unpredictable behavior.
