We desgin a schematic as below. Some question need to check.
1, Is the schematic wrong ?
2, When the 'LED' signal before PIN 3 is given 3.3V trigger level votage, Does PIN 5 DRVn output high level for 30m ? After 30m, it output low level.
3, Druing the 30m of high level output period, when I give a anothe 3.3V trigger signal to PIN 3, Does it restart timer or keep on the first timer ?
