digital I/O in ADuM6402

power-man on Jun 25, 2015

Hello,

My customer uses only 2 (1-1) ports though ADuM6402 has 2-2.

How to treat the pins which are not used.

Can they connect GND?

Hi Power-man:

The ADuM6402 inputs that are not used can be connected to GND (or to VDD). The unused outputs should be left unconnected.

If they only need 2 channels they could also use the ADuM6201, which has 1 forward channel and 1 reverse channel.

Regards, Brian
