Instructions for Use

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.0V to 6.0V.
   • Connect the ground (GND) pin to a stable reference point.

2. Input Signals:

   • Apply input signals such that the low level (V_IL) is below 0.8V and the high level (V_IH) is above 3.5V when V_CC is 5V.
   • Avoid floating inputs; use pull-up or pull-down resistors as needed.

3. Output Signals:

   • The output low voltage (V_OL) should not exceed 0.4V when sinking 4mA.
   • The output high voltage (V_OH) should be at least 4.6V when sourcing -0.4mA.

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 10ns at V_CC = 5V and T_A = 25掳C.

5. Power Consumption:

   • The typical power consumption (P_tot) is 1.5mW at V_CC = 5V and f = 1MHz.

6. Operating Temperature:

   • The device is designed to operate within the temperature range of -40掳C to 85掳C.

7. Handling:

   • Handle the device with care to avoid static damage. Use proper ESD protection measures.
   • Follow recommended soldering profiles to ensure reliable connections.

8. Storage:

   • Store the device in a dry, cool place away from direct sunlight and moisture.

9. Testing:

   • Before integrating the device into a circuit, test its functionality using a known good setup to ensure it meets the specified parameters.

10. Layout Considerations:

    • Keep signal traces short and direct to minimize noise and interference.
    • Use decoupling capacitors close to the power pins to stabilize the supply voltage.
