Hello
Our project consists of the command of a 3-digit display with common cathode using 4000 series circuits and I need some help. We should use a 4093 (astable with trigger schmitt),a 4019 multiplexer (to select which tact to use,the internal from the astable or the external one),a 4029 decadic counter and a 4543 decodifier that commands a 7-segment common cathode diplay.
I have attached a pdf file containing the circuit's scheme.I would like you to look it over and tell me if it has something bad or if I didn't put a good dimension to some resistors or capacitors...
Thanx
