FIELD: computing technology.
SUBSTANCE: invention relates to computing technology and can be used in creation of apparatuses using the EXCLUSIVE OR and (or) EXCLUSIVE NOR functions, e.g., in even parity and (or) odd parity control circuits and multibit adders. The three-input CMOS EXCLUSIVE OR/EXCLUSIVE NOR logic gate comprises a first and a second and from thirteenth to twentieth P-type MOS transistors, from third to twelfth N-type MOS transistors, a VDD high voltage power output, a GND low voltage power output, direct inputs A, B and C, and inverse inputs 
, an XOR output and an XNOR output.
EFFECT: increase in the speed of the known three-input EXCLUSIVE OR/EXCLUSIVE NOR gate and increase in the reliability due to the reduction in the dynamic useful current.
