Instructions for Use:

1. Power Supply:

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

2. Input Signals:

   • Apply input signals with voltages between 0 V and V_CC.
   • Ensure input currents do not exceed the specified limits to avoid damage.

3. Output Signals:

   • The output voltage levels will be close to V_CC for high and close to 0 V for low.
   • Do not exceed the maximum output current ratings to prevent damage to the device.

4. Propagation Delay:

   • The propagation delay times are given for typical operating conditions. Ensure your application can tolerate these delays.

5. Pulse Width:

   • Ensure that the minimum pulse widths for both positive and negative edges are met to avoid incorrect operation.

6. Operating Frequency:

   • The device is designed to operate up to a maximum frequency of 30 MHz at V_CC = 4.5 V. Adjust the frequency based on your specific supply voltage.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Follow proper soldering techniques to ensure reliable connections.

8. Storage:

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