Static Signal Via ADuM 5230

Hi,

 

I am trying to transmit a static signal via ADuM 5230. I am using both the isolated and the externally powered channels. The frequency of the Input logic signal can be <200 Hz. I am observing some false triggers at the signal output of the ADuM chip. With the input logic still high, the output randomly drops to zero for ~1us and the becomes high again.(figure attached).

Is this some issue with the layout or some due to some internal function of the chip?
