ADuM3123 Thermal Derating Curve, Dependence of Safety- Information section for information on immunity to external magnetic fields. Limiting Values on Case Temperature, per DIN V VDE V 0884-10 2 Static common-mode transient immunity is defined as the largest dv/dt between GND 1 and GND2 with inputs held either high or low such that the output voltage remains either above 0.8 × VDD2 for VI = high, or 0.8 V for VI = low. Operation with transients above recommended levels can cause momentary data upsets. 3 Dynamic common-mode transient immunity is defined as the largest dv/dt between GND1 and GND2 with switching edge coincident with the transient test pulse. Operation with transients above recommended levels can cause momentary data upsets.
