Is the answer of the related topic also valid for ISO7421-EP?

If not, how should I connect the unused channel?

Hello,

Thanks for your question.

For unused channels/pins, we recommend to keep the input pin pulled up to VCC or pulled down to GND depending on default state, while the output pin can be left allotting. For more information, please check our FAQ: [FAQ] Can channel input/output pins on a digital isolator be left floating? - Isolation forum - Isolation - TI E2E support forums
