ADUM 5402 VISO settling time and failure behaviour

Hello;

In ADUM 5402, What is the settling time of VISO even after VDD1 input source applied?

Also before VISO genereted what will be the primary signal output's (VOC, VOD) state High, LOW or Hİ-Z?

And also if the VISO failed (no secondary output voltage source) what will be primary signal output's (VOC, VOD) state High, LOW or Hİ-Z?

Best regard,
