I cannot find the 7429 in any TTL data books but I have a couple of dozen. They are 14
pin and I would like to know also so I could use them.

Tom -
Who manufactured your 7429s? I am also having difficulty in finding any info on them.
Right now I cannot locate my early "DATA" book on ICs, but that should have it.
Everything else skips right over 7429. Knowing the manufacturer may help as I have a lot
of the early TTL manufacturers manuals. Happy Holidays - Mike

I have to admit I don't remember a 7429 either. The only things
around that is a FIFO series 7429-xx I think with up to 4k, and
a bunch of drivers, named 7429xxx.

www.sphere.bc.ca has some for sale, and chipdir lists the part. Apparently
it's used in some Tek equipment (Tek # 156-0281-00).

FWIW
I checked the '76 TI TTL Databook, 1980 and 1984 IC Masters and it's not listed
in any of them.

perhaps you have a 74290 or other 7429x chip-
the last digit being obscured. Also with 14pins is
the 74295

Well, I've looked in my two Texas Instruments TTL data books (1979
and 1989 versions) and neither of them list the 7429. Are you sure
it's a TTL 74-series part? Because "7429" is also a valid date code,
indicating 1974, week 29. Is there any alphabetic prefix or
suffix on the number, like SN7429? Are there any other numbers
on the chips?
