IL4822 has internal DC/DC, ISO1452 hasn't, you need external bus side supply. Apart from this point, it's pin compatible.

Thank you. So, the IL4822, has pin 16, VDD2 which is an output. But on ISO1452 part, we have pin 16, VCC2, which is also an output? Am I correct?

Is this what you are referring to?

No, just read the datasheet thoroughly. VCC2 is power input on ISO1452.

Ok, thanks. So, apart from pin 16, for which I need to give external 5V, the other pins are pin compatible with IL4822 for the ISO part to be replaced, correct? Thank you. I will provide 5V to ISO part and replace IL4822 with ISO.
