Does ISO6721 has failsafe output, in the situation of with VCC1=0V, INA=5V?
In my customer's current design, they comes into such an situation, when system powers up, the signal for INX will rise to 5V first and VCC is still 0V.
Is there any requirements for the power up sequence?
If VCC reaches 5V firstly and then INX rises to 5V secondly is required to let ISO6721 work properly.
