Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 4.75V to 5.25V.
   • Connect the ground (GND) pin to a stable 0V reference.

2. Input Signals:

   • Input signals should be within the valid input voltage levels:
     • Low level (V_IL): 0V to 0.8V
     • High level (V_IH): 2.0V to V_CC

3. Output Signals:

   • Output signals will be:
     • Low level (V_OL): 0V to 0.5V
     • High level (V_OH): 2.4V to V_CC - 0.5V

4. Propagation Delay:

   • The typical propagation delay time (t_pd) is 22ns, with a maximum of 34ns.

5. Power Dissipation:

   • The device can dissipate up to 150mW of power. Ensure proper heat dissipation if operating near this limit.

6. Temperature Ranges:

   • Operating Temperature (T_A): -40掳C to 85掳C
   • Storage Temperature (T_STG): -65掳C to 150掳C

7. Handling and Storage:

   • Store the device in a dry, cool place to avoid moisture damage.
   • Handle the device with care to prevent static discharge, which can damage the internal circuitry.

8. Soldering:

   • Use a soldering iron with a temperature not exceeding 300掳C.
   • Avoid applying excessive heat for prolonged periods to prevent damage to the device.

9. Testing:

   • Before integrating the device into a circuit, test it using a known good setup to ensure it functions correctly.

10. Compliance:

    • Ensure that the device is used in compliance with all relevant safety and regulatory standards.
