I was wondering what is the best way to guarantee the presence or
absence (depending on the application) of a one-shot pulse following
power-on of a 555.
It seems that for pulse presence the trigger pin is always grounded
through a capacitor. However, I had pulses missed on power-on. For
pulse absence, a pushbutton is placed on the trigger pin between the
cap and ground, but I had pulses occur on power-on.
So, what's the trick to GUARANTEE that pulses occur or don't on
power-on?
Thanks!
