設計上の考慮事項
Maximum supply voltage should not exceed 5.5V to prevent device damage.
Timing capacitor selection should consider stability and temperature drift, as it impacts pulse width accuracy.
External resistor value sets the oscillation frequency; ensure tolerance for desired output precision.
Proper decoupling with a 0.1µF capacitor on the supply line minimizes noise interference.
Maintain clear board layout around timing components to avoid parasitic effects on pulse width.
