A semiconductor device includes a first conductivity type semiconductor substrate. The multiplexing circuit generates an output signal from a plurality of source signals in response to the selection signal. The mounting device includes one or more torque-transferring fingers, which have looking hooks in order to provisionally clamp the chip holder upon installation. Alternatively, current injection may be triggered by current flowing through the motor, responsive to the current exceeding a predetermined threshold current. The controller maintains a preset headway distance between the host vehicle and the target vehicle, when the host vehicle velocity is less than about 40 KPH, by adjusting the host vehicle velocity in response to the range signal and the range rate signal. Pulsed inputs applied to secondary-stage gates are normally low, disabling the sourcing and sinking transistors in the secondary stage to disable the secondary stage.
