A decoder employing switches such as metal oxide semiconductor (MOS) field-effect devices and diodes in a number of series circuits, each such circuit forming a ring. In the absence of strobe and strobe signals, one diode in one series circuit connects the decoder output terminal to ground. In the presence of strobe and strobe signals, the output terminal is disconnected from ground and, if the control voltages applied to certain of the devices in certain of the series circuits all represent the desired binary value, the strobe signal is conducted via certain of the devices in said one series path to said output terminal.
