Abstract
Composite interface circuit including bidirectional single-conductor bus, first switching circuit, and second switching circuit. Bidirectional single-conductor bus is coupled by first pull-up resistor (R) with first direct current ('DC') input current source having first voltage (V). First switching circuit includes first transistor (T) being coupled with first pull-up resistor (R) and with bidirectional single-conductor bus. Second switching circuit includes second transistor (T) being coupled by second pull-up resistor (R) with second DC input current source having second voltage (V). Second switching circuit further includes voltage divider coupling second transistor (T) with bidirectional single-conductor bus. First and second switching circuits are respectfully configured for being coupled with first transmitter conductor (Tx) and first receiver conductor (Rx) of full duplex universal asynchronous data communication interface.
