At other times, this circuit generates the trigger signal. [Output delay circuit and output latch circuit] The OUT pin is set low when the delay time set by the external capacitor (connected to the output delay time setting pin) elapses after the input goes high. Furthermore, once the output goes low, it is held in that state until the power supply is turned off. [VCC voltage abnormality detection circuit] These circuits monitor the VCC voltage and set OUT low if the voltage exceeds the set range.
