huttojb said:Sorry, I should of said; I didn't want to use a 555 timer (already thought of this) due to cost, I'm gonna be building 50 - 75 of these so I wanted to keep cost to a minimum. I was just wondering is there any cheap and nasty options??
Use another inverter to invert the output.huttojb said:plus the signal is reversed
The circuit is 5 posts above.huttojb said:Could you tell me where the cct is, Is it very expensive to make, don't for get I'm making 50 of these?

Why can't the PIC generate a "negative" pulse?huttojb said:I'm using a PIC to send a pulse and I want this cct I'm trying to get to switch a transistor for approx 1.5 seconds.
I got a positive input and I need a positive output.
I've looked at the dual Monostable on the internet and can't find an example to look and see how it works and re-construct on Multisim??

For 50 circuits you only need 25 Monos or 25 of the 556s.huttojb said:Can I ask. If I have to buy 50 dual Monostable then I might as well buy 50 555 timers???
Jason. Is there any other way?
