Need help in identifying an IC

The attached image is from the DSP I/O board on a Strippit 1000 /XP20 CNC Machines.

The IC appears to be some type of optoisolator, or line buffer. When I scope it out, the Input and output are fairly close to the same, with a little difference in voltage levels.

Any help would be appreciated.
