ISO7821 vs. ISO7821F

Other Parts Discussed in Thread: ISO7821

dear Interface team,

I have a new request from a customer wondering what is the difference between ISO7821 and ISO7821F.

Datasheet specify that the default output is "high" for the ISO7821 and "low" for the ISO7821F device.

Is it the unique difference ?

Also, could you confirm the OOK based modulation scheme is the same for both parts ?

In particular, modulation is active when TX IN is "low" as shown in fig12 page17 of DS. Is it true for the two versions ?

thanks

Paul
