Abstract

A coincidence element responsive to a plurality of input signals for outputting the level of the input signals when said plurality of input signals coincide with each other includes, a serial connection of a first electrically conductive type and a second electrically conductive type MOS transistors of the same number, the number being equal to the number of the input signals, responsive to said plurality of inputs connected between a first power supply and a second power supply; and a CMOS inverter responsive to an intermediate output at the connection of the most lower stage first conductivity type MOS transistor and the most upper stage second conductivity type MOS transistor for outputting a coincidence signal.
