Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 4.5V to 5.5V to avoid damage to the device.

2. Output Voltage Levels:

   • The output high level (V_OH) should be at least 2.4V when sourcing 0.4mA.
   • The output low level (V_OL) should be no more than 0.5V when sinking 16mA.

3. Input Voltage Levels:

   • The input high level (V_IH) must be at least 2.0V to ensure a high logic level.
   • The input low level (V_IL) must be no more than 0.8V to ensure a low logic level.

4. Propagation Delay:

   • The propagation delay times (t_pd(+), t_pd(-)) are critical for timing considerations in digital circuits. Ensure these values are within the specified range for reliable operation.

5. Power Dissipation:

   • The maximum power dissipation is 350mW. Ensure proper heat dissipation if operating near this limit.

6. Temperature Ranges:

   • The operating temperature range is from -40掳C to 85掳C.
   • The storage temperature range is from -65掳C to 150掳C. Store the device in a suitable environment to prevent damage.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow standard ESD (Electrostatic Discharge) precautions when handling and installing the device.
