I'm using a AP2141:
http://www.diodes.com/datasheets/AP2141_51.pdf
to disconnect a circuit from another.
It is connected as following:
IN 4V
EN 5V
OUT 10k pull-down (for test purpose)
On the OUT pin I read the same voltage applied to the IN pin, 4V.
I checked it really is an AP2141 (active low).
I can't understand why I read 4V instead of 0V.
There are several boards on my desk, all with the same behavior.
Perhaps I misunderstood something in the ds?
Thanks!
