I've been reading this description of the cd4047b an IC which Uncle scrooge gave me https://www.electro-tech-online.com/custompdfs/2008/04/cd4047b-1.pdf the thing is I can't understand what the maximum input voltage is. I think it's 0.5 volts so if I am correct then does anyone know of a voltage regulator I could use for this circuit. Also am I right in thinking that I would need a couple of transistors to boost up the output voltage to drive a couple of mosfets. Can I have this exact circuit **broken link removed** excluding everything to the left hand side of the sn7400. ![Eek! :eek: :eek:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
