Does anyone have a cross-refernece list for Xerox house-numbered ICs?
The particular one I am looking for is 733W21L1
It's an 8 pin DIL package. Pins 1,5,8 are not used on the PCB. The others
are the conventional op-amp pinout (2 = -ve input, 3 = +ve input, 4 = 0ve
supply, 6 = output, 7 = +ve supply). I've replaced it with the obvious
741, and am getting rather better results than with the original (the
output of which was stuck at 6V), but I'd like ot know if the original
has any odd characteristics.
