Datasheet / Info for Motorola SC5330 IC?

I'm in the middle of working out the pinout for the power supply connector
on the MDP-1000. I'm aided somewhat by a set of test points on the
backplane, unfortunately the "+" and "-" symbols (in the solder mask labels
next to the test points) are nearly indiscernible, so I'm trying to verify
that I'm not mixing up + and - 15V.
On the core memory boards are eight Motorola SC5330 IC's (datecodes from
early 1969), which have pins connected to both the + and - 15V lines -- if
I can find a datasheet I could pretty easily confirm which is which.
Trouble is I can't find anything on this chip. I've scanned through the
databooks on Bitsavers, no luck. Anyone have any ideas?
Here's a picture in case that helps at all:
