Abstract: In some examples, a circuit includes a sink/source mode detector configured to compare a voltage provided at the first I/O terminal of the circuit to a first reference signal; determine, responsive to the voltage provided at the first I/O terminal exceeding the first reference signal, that the circuit is in a source mode; determine, responsive to the voltage provided at the first I/O terminal not exceeding the first reference signal, that the circuit is in a sink mode; responsive to determining that the circuit is in the source mode and an input signal of the circuit has a value less than a second reference signal, control a first switch to form a first current path between a voltage supply terminal and the first I/O terminal of the circuit; and responsive to determining that the circuit is in the sink mode and the input signal has a value greater than the second reference signal, control a second switch to form a second current path between a ground terminal and the first I/O terminal of the circuit.
