Equivalent Circuit Block Diagram
[Trigger signal generation circuit]
When the input pulse (50% duty) is held low or high, OUT1 is set high. 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.
[VCCvoltage abnormality detection circuit]
These circuits monitor the VCCvoltage and set OUT low if the voltage exceeds the set range.
