Is it all right even if I connect 7 pins to the GND?
I mistook ISO7240CF for ISO7240C and have got a wrong layout.I mistook ISO7240CF for ISO7240C and have got a wrong layout.
ISO7240CF 7pin=DISABLE
ISO7240C 7pin=NC

Masashi,
Connecting a NC pin to GND is fine, as it isn't internally connected to the rest of the circuit. Pin 7 in your case would be connected to GND1, not GND2, correct?
Thanks,

HI Jason
Thank you for an answer
Pin7 connected GND1
It connected to GND1 with pin2(GND1) and pin8(GND1) Of ISO7240
