I have to admit that the "DS" from the part number does make it sound
like National Semiconductor stuff from the mid-late 70's, but I don't
see it listed in any of the databooks here.

Many "DSnnnn" series chips show up on DEC boards, and I think at least
some of them denote hand-picked chips from a more "conventional" part
