Anyone got a source for SA605 or SA615? I want to build the 1-chip

them.
Nominally these are Phillips parts (now NXE or whatever). They use the
'SA' 'NE' etc., for indicating temperature ranges -- I know I've had
trouble finding '602s with one prefix, and no problem with the other.

I recall reading that the SA602/605's were discontinued and replaced by
the '612/'615. Because of demand some of these were relabeled and sold
as 602/605's to satisfy customers who didn't believe that the parts were
interchangeable. They are.
