Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the specified range of 2.0V to 5.5V. The device is not guaranteed to function correctly outside this range.

2. Input Signals: Apply input signals that meet the input low and high voltage requirements. For proper logic level recognition, input voltages should be below 0.8V for a low signal and above 2.0V for a high signal when VCC is 4.5V.

3. Output Handling: When driving loads from the outputs, ensure currents do not exceed the ratings to prevent damage. Outputs are designed to sink more current than they can source.

4. Timing Considerations: Account for propagation delay in your design. At VCC = 4.5V, expect a typical delay of 11 nanoseconds.

5. Thermal Management: Operate the device within its temperature limits. For extended life and reliability, avoid exceeding the maximum operating temperature of 85掳C.

6. Storage and Handling: Store the device in environments where temperatures do not drop below -65掳C or rise above 150掳C to prevent physical damage.

7. Electrostatic Discharge (ESD) Sensitivity: Handle with care as the component is sensitive to ESD. Use appropriate ESD protection measures during handling and installation.
