ive been trying to come up with a circuit that would allow me to use a decade counter as a 'programmable' frequency divider. what i mean, is to be able to input a bcd (or decimal, if necessary) number, and have the base frequency divided my that number (eg. divide by 0 through 9, 0 being no pulses sent). ive come up with an idea that seems to work fine, but it requires 6 discrete ICs. (i actually need several of these for one project, so 6 ICs each is a little excessive). ive posted a schematic of it so you can really see what im shooting for. flipping through digikey, i found the cd4522b, which sounds like it would work perfectly for my design, although 'not recomended for new desgns' is stamped on the datasheet. has anyone used this chip before? i dont need to order anything else right now, so doing so just for those would be a waste of time and money if they dont work for my application. any suggestions welcome!! thanks
