Wondering if anyone can help me figure out the pinouts for an opto-isloator
I found in the junk box - several years ago I started to hook it up for a
CW keying circuit and probably got it to work, but can't remember now how I
did it.
The chip has "NTE 3041" on the top of it and I seem to remember it coming
in a "ECG" carton. Anyone know where I can find the pinout diagram for this
beast?
Alternatively, I recall some conversation recently about the 4N33 chip -
does Radio shack carry those (or a reasonble substitute)?
Thanks
