And of course a
4040 from Intel is a 4-bit microprocessor, from RCA it's
a 12 bit CMOS counter. I can never rememebr what the 4004 is in the
4000-eries CMOS, it's sufficiently rare that none of the data books I
have to hand list it.
ur kiddin. Just prefix 74{c, hc, hct} and the 4xxx number and you
get it's function and pinout. Whats scary is that I have old databooks to support
the old parts
I HAVE and use.
So do I. Valves, CRTs, DTL chips, and so on.... I even keep old component
catalogues so if I find some part marked with, say, an RS components
stock number I can look it up and find the specs.
