:What about the 4017? This is a Johnson type decade counter - you :put in a clock and each of it's 10 outputs goes high in turn. It :has the usual reset and inhibit pins. : :problems- :1. The pinout was tampered with by the KGB to make it totally : impossible to design a PCB for it. : as a newcomer, i find this with many ic's. Is there really some sense to the pinouts ( in general ) or are the pinouts driven enitirely by internal chip circuit design considerations? -- / george jefferson \/ * george@mech.seas.upenn.edu
