Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the specified range of 1.65 V to 3.6 V.
   • Connect V_CC to the power supply and GND to ground.

2. Input Signals:

   • Input signals should be within the valid input voltage range: 0.0 V to 0.8 V for low logic level and 2.0 V to V_CC for high logic level.
   • Avoid exceeding the maximum input voltage to prevent damage.

3. Output Signals:

   • The output low voltage (V_OL) should not exceed 0.4 V when sinking 4 mA.
   • The output high voltage (V_OH) should be at least 2.4 V when sourcing -0.4 mA.
   • Ensure the load connected to the output does not exceed the maximum current ratings.

4. Propagation Delay:

   • The propagation delay times (t_pdLH and t_pdHL) are typically 3.5 ns at V_CC = 3.3 V and T_A = 25掳C.
   • These values can vary with temperature and supply voltage.

5. Temperature Considerations:

   • The device operates reliably within the temperature range of -40掳C to 85掳C.
   • Store the device in a temperature range of -65掳C to 150掳C to avoid damage.

6. Power Dissipation:

   • Ensure that the power dissipation (P_D) does not exceed 700 mW to prevent overheating and potential failure.

7. Handling and Storage:

   • Handle the device with care to avoid static discharge, which can damage sensitive components.
   • Store the device in a dry, cool place to prevent moisture-related issues.
