While we're on the subject,
can I ask if anyone knows what a
Mmic
29302BT
9508
PHIL 4D47US-2
might be?
I found several, for ?5V? to ?3.3V? converters,
and could use the pinouts, there are 5, from a TO
style case. The writing is exactly as above.
There is another chip in the MAX232 series someplace
that creates 12 V from 5V for serial uses other that
what a 232 chip is normally used for. It just needs
some capacitors for the charge pumps.
Equally interesting, if somebody finds it.
