need data sheets for IC ULN2111A

[WB9OMC]

I just built a Ramsey FR1 FM receiver, which works pretty well and to complete my documentation, I need the data sheet for the ULN2111A.  Ramsey will not even
tell me who made it, which is disappointing as I do
not see what difference it makes to them.....but,
a web search has also proven pretty useless so far.
I was trying to negotiate the National Semiconductor
site for the LM2111 which is supposedly a cross
reference but their site is so anally retentive and
stupid that you can't find anything you want!

If anyone out there has the goods on this IC, please
let me know.

Thanks!
