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.
