Power Supply Connection:
- Connect the VDD pin to the positive supply voltage within the specified range of 3V to 18V.
- Connect the GND pin to the common ground.
Input Signal Handling:
- Ensure input signals are within the valid logic levels:
  - Logic HIGH: Greater than or equal to VIH
  - Logic LOW: Less than or equal to VIL
- Be cautious of input currents; they should not exceed the maximum leakage current specification.
Output Load Management:
- Outputs can drive loads with respect to VOH and VOL specifications.
- Avoid exceeding the output short-circuit current limits to prevent damage.
Propagation Delay Consideration:
- Account for the propagation delay in timing-sensitive applications, ensuring that signal transitions are managed correctly.
Thermal Management:
- Keep the operating temperature within the specified range (-40掳C to 85掳C).
- Monitor power dissipation to avoid overheating, especially when operating near the maximum PD limit.
Handling Static Electricity:
- Handle the device with care to avoid damage from electrostatic discharge (ESD).
Storage and Handling:
- Store in a dry environment and handle according to ESD guidelines to ensure reliability and performance.
