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.
However for us who kept those old and valuable manuals like Signetics
8xxx series and the RCA databook series (my 1973 set was some 8 books)
I do have data for RCA 4xxx and a lot of other oddities.

Either
someone at Hynix has a sense of humour, or they have run right
out of IC codes and have come full circle to 2708 again.
Several years ago, Motorola/IBM used the part number "7400" for some of their
PowerPC chips. -tony
