While it is weird to have SLT on an SMS board, it is
well within
reason. SMS (the form factor for the board at auction) was used for 25
some years.
The part number (397563) puts in pretty much in the
S/360 era.

A lot of 360 I/O lived on in the 370 family.
The 370/135 had an Intergreate Printer Adapter (IPA) feature that would drive a 1403N1
and an (ICA) Intergrated Communications Adaptor,
It looks like a line driver for/from some kind of I/O to me.
