Abstract
A polarity independent differential data transceiver receives a differential voltage signal and outputs a first logic state when the differential voltage signal is in a positive voltage differential range and/or when the differential voltage signal is in a corresponding negative differential voltage range. The differential data transceiver will output a second logic state in response to receiving a voltage differential signal that is in an intermediate differential voltage range near zero between the positive differential voltage range and the corresponding negative differential voltage range.
