Does anybody know if the DEC8235 is the same as the
National DM8235?
Doesn't look likely. The DM8230 isn't the same as the Signetics 8230.
The DEC82xx parts seem to be the Signetics 82xx parts.
Mouser claims to be able to order NTE8235, but
there's no order pending or
delivery date. ($9.09 each.)
http://www.rselectronics.com/ seems to claim stock.
This company search says they have non NTE parts. I used them in 1999 to
get a part and the minimum order then was $50.

Who knows what has changed since then, the search is using an outside site.
They also list the MM57109N from another message.
Post back if you do use them.
