7.3.4 Polarity Free Operation

THVD8000T is immune to A and B polarity at the receiver input in OOK mode. The receiver data comparator only checks for the receive input signal magnitude, ignoring the polarity, to determine the logic level. Note that reversing the polarity does result in degraded pulse width distortion.
