I believe RTL was 3.6V. But I could be wrong, it has happened.

I also have a bunch of them. I made one of my first (the first actually
used
tubes and an RC network) electronic keyers using those Fairchild devices.
To
the best of my recollection they are standard 5 volt devices. Brings back
a
lot of memories well over 40 years ago. They were not around for that long
as then DTL became the craze. 73 - Mike

Wasn't that a RTL 923 and 914? I still have a few from my learning days.
