What is an M750 "Line I/O control" for?

I asked this in alt.sys.pdp8, but didn't get the answer, so I will try here:

When I got my PDP-8/i (oh so many years ago), it came with a supply of
flip-chip spares. Among them are 24 M750s, which I can't find any
info about, except the phrase "Line I/O Control".

What are they for? They aren't for any of the 8/i's built-in options,
so there must be an external option that calls for them? Is there a
reason for me to keep so many of the things?

Thanks!
