I ordered an LT1054 to use for the 9V inverter. I’ve read that they are compatable but I also saw that I would have to add a cut between pins 1 and 8 to use the LT1054, is that right?
The ICL7660S is pin 8 too. But to use it in boost mode so the oscillator is running at the higher frequency there is no cut so pin 1 is getting 9V too. The 9V wire may go to the pin 1 row in the layout you're looking at but that is only because pin 1 and 8 are connected, it could connect anywhere on that row.
