Default TI SN75494N - anyone have any info?

This is an old chip from TI, apparently a LED driver of some sort according to the few scattered bits of information I'm finding online. It's also used as the light bulb and speaker driver in an old Milton Bradley "Simon" game I'm trying to fix up.

Apparently SGS Thompson may have made a version of the chip also.

Thanks!

That particular link didn't work, but I tried several of the "datasheet download" sites and finally came across one that wasn't spam. Got what I needed to know.

Thanks!
