i have made the following circuit for two voltage comparator monoshot, whose output comes to gether as AND gate and the output of AND gate goes to NC switch of 555.
When both the comparators are triggered, the output goes high, in turn closing both the transistor switch Q1 and Q2. This closes the NC switch of 555.
When either of the voltage comparator goes low, the the corrosponding Q1 or Q2 opens there by opeaning the NC switch of 555 timer and triggering the timer. i want the 555 timer to be trigged when any one of the voltage comparator goes low after being triggered.
kindly let me know your views especially on the component values.....
(please excuse the poor connecting line from Q1Q2 to 555 timer NC switch, the lines are ment to be wires and i could not include them in the rimu schematics software that i am using, hence i did a draw job)
