For what its worth, I used to use this chip some years ago, but it has
been obsolete for at least 8 years.

I know 'cos I spoke to a GI rep before designing it in to the product
and asked specifically if it was safe to design it in. I was told it was.

Six months later when trying to place pre-production quantity orders I
was given the news that it was no longer available. We had good success
it from some of the difficult to find IC suppliers though.
