Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the specified range of 4.5V to 5.5V.
2. Output Voltage Levels:
   • For a low output (VOL), ensure the current does not exceed 4.0mA to maintain output below 0.1V.
   • For a high output (VOH), ensure the current does not exceed -4.0mA to maintain output above 2.7V at VCC = 5V.
3. Input Handling: Keep input leakage current within 卤1渭A by ensuring input voltages are stable and within the operating range.
4. Timing Considerations: Account for a propagation delay of up to 6.5ns in your timing calculations, especially in high-speed applications.
5. Power Management: The device consumes approximately 20渭A in quiescent state; design your power management system accordingly.

Note: Always refer to the specific datasheet provided by the manufacturer for detailed specifications and additional information.
