I built a circuit using a 555 timer, and I want it to be powered from a 9VDC battery. Only, 555s use current even when their output is low. I thought about changing it for a monostable multivibrator, having the ground of the chip connected to the collector of an NPN transistor, the output also tied to the base, so that when the base was activated (via a momentary press button), the multivibrator would keep the transistor base high until the output was off, and not use any power when the output was low. But, I'm not sure if that idea will work well. So I am asking if there is anything I can do to keep the 555 from drawing current when not in use. Control of the circuit is done only with the momentary push button, which activates the 555 trigger. No on/off switches or anything like that. Thanks for any ideas.
