Instructions for Use:

1. Supply Voltage (V_CC):

   • Ensure the supply voltage is within the range of 2.0V to 5.5V to avoid damage to the device.

2. Output Levels:

   • The output low voltage (V_OL) should not exceed 0.4V when sourcing 16 mA.
   • The output high voltage (V_OH) should be at least 2.4V or up to V_CC - 0.4V when sinking -4 mA.

3. Input Levels:

   • The input low voltage (V_IL) should be less than or equal to 0.8V.
   • The input high voltage (V_IH) should be greater than or equal to 2.0V and can go up to V_CC.

4. Propagation Delay:

   • The propagation delay time (t_pd) is typically 12 ns with a maximum of 25 ns under standard conditions (V_CC = 5V, T_A = 25掳C).

5. Power Dissipation:

   • The maximum power dissipation (P_D) is 500 mW. Ensure proper heat dissipation if operating near this limit.

6. Operating Temperature:

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

7. Handling and Storage:

   • Handle the device with care to avoid static damage. Store in a dry, cool place away from direct sunlight.

8. Pin Configuration:

   • Refer to the datasheet for the specific pin configuration and ensure correct connections to avoid damage.

9. Testing and Verification:

   • Before integrating the device into your circuit, perform initial testing to verify all parameters meet the specified values.
