databook I have goes

to about 1970, and is a TI book with the standard, H,
and L series in it
only.
When I'm working something out that needs a dual one-shot, I use a 96LS02.
And let's not forget the Signetics 8Txxx TTL stuff.
Japanese numbers can be a problem if they're not conventional. Mitsubishi
and Fujitsu particularly. I've got lots of "what the heck is this thing"
samples of both.
