Abstract
A state-detection circuit facilitates the detection of the state of an input pin relative to several different types of input circuits. According to an example embodiment, a state-detection circuit includes a plurality of comparators and circuit components, configured to provide a plurality of binary output signals that collectively indicate a state of an input pin to which the comparators are coupled. The state-detection circuit is configured to facilitate the detection of several different types of input circuits, based upon the binary output signals.
