*) The AC Voltage on Coil is limited by the on chip voltage
limitation circuitry. This is according to the parameter Icoil in
the absolute maximum ratings.
Stresses above these listed maximum ratings may cause
permanent damage to the device.
Exposure beyond specified operating conditions max affect
device reliability or cause malfunction.
Handling Procedures
This device has built-in protection against high static
voltages or electric fields; however due to the unique
properties of this device, anti-static precautions should be
taken as for any other CMOS component.
