設計上の考慮事項
Ensure a stable power supply within the 2.25V to 5.5V range for optimal functionality.
Use accurate resistor values to prevent deviation in pulse timing; e.g., a 10kΩ resistor gives consistent width accuracy.
Avoid excessive parasitic capacitance at the input, as it may affect timing precision.
Select timing resistors to account for the required pulse range (e.g., longer pulse tasks require higher resistance).
Confirm the environment temperature range (-40°C to 85°C) to match the device's operational specifications.
