It would be great to have an online source for RTL
specs, like most people I
have no RTL docs.
But there are many RTL families, and only some are compatible. RTL
isn't a brand name, it means only "resistor-transistor logic". TTL
is also quite accurately described as "resistor-transistor logic",
"branding" was done there certainly to distinguish, and today,
nearly all "TTL" families died off except the TI 74xx stuff, but
you can't extrapolate backwards.
(I don't mean to start a pissing match over meanings of acronyms
(TTL, RTL, DTL, etc), I speak loosely to warn about not taking
names too seriously.)
I have some few datasheets for early logic families here:
