Hi,
Pls, have a look at this description of Signetics 25000 series 9046 XN
component:
http://pichotjm.free.fr/humr/2.html
Can you explain me, what is Vff? Is it a good idea to decrease this voltage
in order to increase reliability?
But what will happen with our 50 Hz european supply?
I need help...
(please, answer with simple english)
