it's possible to use the ADUM142E and ADUM1251 in mixed powersupply mode?
VDD1 =+3V3 and VDD2=1V8
In the datasheet is always explained the typical voltage range for 5V/3V3 or 1V8
the ADuM142E and ADuM1251 are 'isolators', hence no connection between VDD1/GND1 towards VDD2/GND2.
As both parts offer signal level translation this scenario demands for mixed power…
