All voltages are relative to their respective ground. See the Applications

Information section for information on immunity to external magnetic fields.

Static common-mode transient immunity is defined as the largest dv/dt

cause momentary data upsets.

3

Dynamic common-mode transient immunity is defined as the largest dv/dt

transient test pulse. Operation with transients above recommended levels

can cause momentary data upsets.
