Looking for a simple monostable circuit

[tijoseymathew]

i want to build a circuit which once triggered should have constant o/p as 1 unless reset.
any ideas :?:
it should have minimum parts!!

Re: monostable

If the output should be 1 an undefined amount of time, not just a constant period, before reset, you need a latch or bistable.
Use 74LS74, or 4013, connecting the D and CLK inputs to ground. Use S to set and R to reset.
You can build the same circuit with 2 transistors and some resistors.

monostable

that is good
can u elaborate on the 2 trnsistor method ??
