Data Sheet ADM3260 DIGITAL ISOLATOR DC SPECIFICATIONS
All minimum/maximum specifications apply over the entire recommended operating range, unless otherwise noted. All typical specifications are at TA = 25°C, VDDISO = 3.3 V or 5 V, and VDDP = 3.3 V or 5 V, unless otherwise noted. All voltages are relative to their respective ground.

This is the minimum difference between the output logic low level and the input logic threshold within a given component. This ensures that there is no possibility of the device latching up the bus to which it is connected.
