CAUTIONS: The BiCMOS inherent to the design of this component increases the component’s susceptibility to
damage from the electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and
assembly of this component to prevent damage and/or degradation which may be induced by ESD.
