Great something to try, thank you. I seem to remember the last time I tried
this a year or more ago it was frustrating. Google on tmp47p443 and there it
is, only data-sheet archives and aggregators. First hit is DigChip.com a
member only site but, it does show it to be Toshiba part. Go to Toshiba's
web site and search, not found, that explains why the manufacturers site
didn't come up in the Google search. Second result is clearly an obsolete
parts sales site so I skip it. The 3rd result is datasheets.org.uk I try it
and success, the tmp47p443 data sheet without any signup.

That was too easy, I do seem to recall that it was harder finding data
sheets for obsolete parts. I check the date on the datasheet and see it's
from 2000 so I try an older part. The MC146823 was obsolete more than 10
years ago but, there's a copy of the data book pages at the first result,
datasheet4u.com. I try some more:
28c16 - 3rd result alldatasheet.com
MC146818 - 1st result datasheetcatalog.com
ad7533 - 1st result original manufacturer Analog Devices

Well either my memory of how hard it was to find datasheets for obsolete
parts is wrong or, Google and the free datasheet sites have improved things.

In any case it's worth noting that these sites have many old datasheets for
free.
datasheets.org.uk
datasheet4u.com
alldatasheet.com
datasheetcatalog.com
datasheetarchive.com
