ISO7310C: ISO7310C VCC1 GND2 connection

Hiroaki Yuyama TED

Part Number: ISO7310C

Dear, support team.

For ISO7310C, VCC1 and GND2 are 2 wires each from the package.
Is it necessary to connect both wires in the PCB layout?

We are considering whether our customers can use it in the replacement of ADuM1100.
Of the two wires on the ADuM1100, one is an optional connection.

Hi Hiroaki-san,

Thanks for reaching out.

The two VCC1 pins and the two GND2 pins are internally connected to each other and connecting only one of them is sufficient. Hence, you can go ahead and use either of them. Thanks.

Hi Rao-san,

Thank you for your answer.
I understand that VCC1 and GND2 can be connected to the PCB with one wire.
