qOperation of Output Delay

Supply Voltage

Capacitor Voltage

Output Voltage

external capacitor starts, then capacitor voltage increases. Until the capacitor voltage reaches to CD

Pin Threshold Voltage, Output Voltage maintains “L”. When the capacitor voltage becomes higher than

CD pin threshold voltage, Output Voltage is reversed from “L” to “H”. Where, the time interval between

the rising edge of Supply Voltage and Output Voltage Reverse point means Output Delay Time.

q Output Delay Time

Output Delay Time (tD) can be calculated with the next formula.

RD is internal resistor and set at 6.5M

external capacitor. Therefore,
