As for your VISOOUT,
If I pull the current over 46mA by external load not VISOIN, what trouble has come?
Work current limit function if this have?
Otherwise work the thermal shut down? So enabled all working?
As for your min data rate on your datasheet,
If I use the communication by under 16MHz slower, can the communication work well?
I think this only happen "slow communication" correct?
As for your data rate on your datasheet,
What is the max data rate with ability?
