 Its a new chip, I guess its the replacement of the 3484. There's a little
info on it at the Motorola site. For the full data sheets, you have to use
the Motorola fax service. Not that it really matters, as it won't be
available for quite some time. Plus, as someone else pointed out, it doesn't
appear to be the peak/hold circuit I was under the impression that it was.
If you want I can set up the data sheets for ftp.

Later,
