waveforms-tim58.gifHello,

Where does the current go when a 555 is discharging. Does the discharge pink act as a sink and if so where does the current start from during the
discharge process ?

Thanks

Hi E,

So, if I am right, current flows into the discharge pin and if Q14 is conducting, through the collector and out through the emitter to ground ?

But in the 555 circuit I included in my original message can you please explain where the current starts from before it flows into the discharge pin ? I hope this makes sense.

Thanks

Hedgehog.
