Can these isolators withstand negative voltage at the input V? If so , how much? ADuM150N/ADuM151N/ADuM152N

Question

Can someone help with this? 
 I'm looking at the ADuM150N/ADuM151N/ADuM152N for an application due to its small footprint and multiple channels. 
 Can these isolators withstand negative voltage at the input with respect to GND? If so , how much? 
 A resistor divider will be placed at the input for scaling purposes. As a result , the current can be limited limited if sourced from the chip. Still in the component selection phase. 
 Thanks for your help

Hi Shiraz, 
 The ADuM15xN has ESD diodes between the I/O pins and the VDDx and GNDx. If the input signal level was lower than a diode drop below the GNDx pin on the same side, current will flow. 
 Note the Absolute Maximum Ratings (Table 14). Input pins need to stay between -0.5 V and VDDx + 0.5V.
