A ADUM1400 has failed.
Regardless of input voltage, only one channel outputs high level.
The other three channels are operating normally.
I suspect the cause is that the input voltage has exceeded the absolute maximum rating or ESD.

The 4-channel ADuM1400/1401/1402 family will support the 40 MHz rate and provide noise segregation.
Hello ADI Support:
My customer is currently designing an isolated serial card using the ADUM 5400. The PCB dimensions will be the standard PC-104 card size. Along with the ADUM 5400, They will also be using the ADUM1400 to isolate other signal lines…
can you say me are correct placed on the board? The distance between elements is measured 4mm. We will use FR4 material for PCB(1.2mm 4 Layers).
Hi, I have found a strange behaviour in the ADUM1400BRWZ: the datasheet says the pin 7 shouldn't be connected but if I don't connect it the inputs are disabled. Then I tried to connect pin 7 first to GND1 and then change it to VDD1 to see the diferences…
