Abstract
A multiplexer for an ultrasonic ranging device for a vehicle having a resettable digital counter is disclosed herein. The digital counter receives a plurality of pulses from an oscillator and provides a counter output signal indicative of the stored count of the number of pulses. A plurality of logic gates are connected to the digital counter for control thereby. A plurality of ultrasonic transducers are connected to the logic gates, the logic gates sequentially energizing the transducers in response to the stored count in the digital counter.
