Instructions for Use:

1. Power Supply: Ensure the supply voltage (VCC) is within the range of 2.0V to 6.0V.
2. Input Signals: For reliable operation, input signals should have a low voltage (VIL) not exceeding 0.8V and a high voltage (VIH) at least 2.0V.
3. Output Signals: The output low voltage (VOL) should be no more than 0.1V when sourcing up to 4mA. The output high voltage (VOH) should be at least VCC-0.2V when sinking up to 4mA.
4. Timing Considerations: The propagation delay time (tpd) is typically 19ns under standard conditions (VCC between 4.5V and 5.5V).
5. Thermal Management: Keep the operating temperature (Topr) within -40°C to 85°C for optimal performance.
6. Power Consumption: Monitor the power dissipation (PD), which should not exceed 100mW at room temperature (25°C).

Note: Always refer to the manufacturer's datasheet for detailed specifications and additional information.
