Hi Sir,

Can ADuM5211 support 1.8V Uart?

In the datasheet, the min of Logic High Input Threshold is 0.7 Viso and 0.7Vdd1. Does this mean chose the lowest for the min value?

For example, Viso is 3.3V and Vdd1 is 5V. Does the min of Logic High Input Threshold is 3.3*0.7=2.31V?

Edit Notes

Add Logic High question.
