74188, 74287, 74288, 74387

They're probably obsolete.

Try searching for the LS or HC equivalents i.e 74HC188 or 74LS188, no one uses TTL any more, it's inferior and more expensive as it's not made any more. I remember looking for the 7400 at Maplin and noticed how much more expensive it was than the 74LS00 and that was 15 years ago.

It is annoying when that happens.

I often ask another question and only before I bother to do something.if they reply.

Never mind the datahseets are now here for anyone else that wants them, until the forum crashes again and we loose all the posts.
