Power Supply Connection:
- Connect the supply voltage (VDD) within the operating range of 1.65V to 5.5V.
- Ensure a stable power supply to avoid malfunction.
Input Handling:
- Inputs should be kept within the specified voltage thresholds to prevent damage.
- Use pull-up or pull-down resistors as necessary to ensure stable logic levels.
Output Handling:
- Do not exceed the maximum output source and sink current ratings.
- External components connected to the outputs should have appropriate current limiting resistors if needed.
Signal Timing:
- Account for propagation delays in your design to ensure reliable signal transmission.
- Verify that the timing parameters meet the requirements of the system.
Environmental Considerations:
- Store and operate the device within recommended temperature and humidity ranges.
- Protect against electrostatic discharge (ESD) during handling.
PCB Layout:
- Place decoupling capacitors close to the power pins to reduce noise.
- Follow best practices for PCB layout to minimize interference and improve performance.
