Abstract
A fail-safe differential receiver having a differential amplifier adapted to receive first and second differential input signals and generate a differential voltage. A peak detector is coupled to the differential amplifier for generating a detect signal and a comparator is coupled to the peak detector for comparing the detect signal to a threshold voltage and providing a comparison signal. A directing circuit is coupled to the differential amplifier for receiving the first and second differential input signals and is coupled to the comparator for receiving the comparison signal. An output amplifier is coupled to the directing circuit. The directing circuit selectively directs the first and second differential input signals to the output amplifier as a function of the value of the comparison signal from the comparator.
