Patent number: 9705400Abstract: An output stage configuration with four configurable input/output terminals and four switches is specified. Each switch has a first main terminal, a second main terminal and a control terminal, which receives a control signal for controlling the open or closed state of the switch. The output stage is included in a circuit together with a first control apparatus and a second control apparatus. When a control stage of the first control apparatus is connected to the output stage, a control stage of the second control apparatus is electrically disconnected from the output stage, and the output stage operates in a first operating state. When the control stage of the second control apparatus is connected to the output stage, the control stage of the first control apparatus is electrically disconnected from the output stage, the output stage then operating in a second operating state.Type: GrantFiled: June 2, 2014Date of Patent: July 11, 2017Assignee: OPTIS CIRCUIT TECHNOLOGY, LLCInventors: Philippe Sirito-Olivier, Patrizia Milazzo, Angelo Nagari
