5V and early ICs

[Brent Hilpert]

Below I have interspersed the correlations from my 1965 TI catalog
(TI "1965 Semiconductor and Components Catalog") with further
comment following:

       - SN53x are mentioned
       - Series 73 industrial modified-DTL are mentioned in a special
         late-additions fold out attached to the back.
         The SN72x/73x RTL series is apparently distinct from these.

       - 5400,5410,5420,..5470 listed
       - 74xx not mentioned

My 1965 catalog does not specify a month, although it lists several
other TI publications with the latest publication date being Mar 65.
It would appear the catalog I have was but a few months before the one
you have. Between the two of them it would seem reasonable to conclude
the 7400 series was introduced in the summer of 1965, a few months after
the 5400 series.

If you are ever inclined to produce scans of these, I'd be interested; someday
I'd like to start compiling a list of the numerous early IC series.

On another note, the catalog I have also lists "gallium-arsenide infrared
sources" and "solid-state light emitters" (for the latter: "Spectral emission
matched to silicon light-sensors", no mention is made of use as a visible
indicator).
