Hello everyone,
given my lack of expertise in the electronics domain, I hope a third party versed in the matter may guide me to a better understanding. Specifically, I wish someone stresses for me (something datasheet doesn't do for the everybody) what are the differences of performance that would make someone changes a mux of the old 4000 Series (e.g. CD4051; I think it was introduced by the now-extinct RCA company and numerous present companies still produce it using the same nomenclature as RCA; CD: CMOS+Digital and the serial number of the 4000 category) for a revised version like the DG509A (DG: Delay Generator tech?; I think the suffix "A" refers to either the inputs/outputs are buffered or not; here not buffered?). Regarding datasheets, I know the present DG509A was manufactured by MAXIM whereas the previous CD4051 manufacturer details are lost. It was physically replaced, but the circuit design still left traces of that change. Knowing better the reasons of such change may lead me to the right direction in understanding the whole circuit. Sadly, the circuit designers are gone and nobody near me can really help retracing the mental process of the circuit.
For as much I could collect information regarding the matter, it seems the older technology of the 4000 Series is less adapted to fast-processing ICs while the kinds like DG509A are better for that kind of job. The pinout is different between those two, so it might be a reason...for components setting optimization. For now, I leave to this and if clarifications are needed to purvey a better answer, I'll be there for this. I wished to be more detailed, but I am a tad at lost.

Shamash.
