Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 1.65 V to 5.5 V.
   • Connect the V_CC pin to the power source and GND pin to ground.

2. Input Signals:

   • Input signals should be within the valid logic levels:
     • High: V_IH ≥ 2.0 V or V_CC
     • Low: V_IL ≤ 0.8 V

3. Output Signals:

   • When driving loads, ensure the output current does not exceed the specified limits:
     • Output high (V_OH): I_OL = -4 mA
     • Output low (V_OL): I_OL = 16 mA

4. Propagation Delay:

   • The propagation delay time (t_pd) is the time it takes for a change in input to affect the output. At V_CC = 3.3 V and 25°C, the maximum delay is 8 ns.

5. Temperature Considerations:

   • The device is designed to operate within an ambient temperature range of -40°C to 85°C.
   • Store the device in an environment with a temperature range of -65°C to 150°C.

6. Power Dissipation:

   • The maximum power dissipation (P_D) is 340 mW. Ensure proper heat dissipation if operating near this limit.

7. Handling:

   • Handle the device with care to avoid static damage. Use appropriate ESD protection measures.

8. Layout and PCB Design:

   • Use short traces to minimize parasitic inductance and capacitance.
   • Place decoupling capacitors close to the V_CC and GND pins to reduce noise and improve stability.

9. Testing:

   • Before finalizing the design, test the device under various conditions to ensure reliable operation.
