PROBLEM TO BE SOLVED: To provide a decoder circuit realizing high speed operation without increasing remarkably current consumption. SOLUTION: The circuit is provided with an output driving section provided with a PMOS transistor for transitting an output signal to a high potential from a low potential by switching an input signal to a low potential from a high potential and a NMOS transistor for transitting an output signal to a low potential from a high potential by switching a reset signal externally supplied to a high potential to a low potential. Two inverters whose input and output terminals are connected respectively, a driver circuit having an output holding section for holding an output signal of the output driving section and a latch section for holding a gate potential of the NMOS transistor of the output driving section at a low potential even if a reset signal is made a high potential when an output signal of the output driving section is a low potential and for preventing turning on of the NMOS transistor is provided at the last stage of the decoder circuit.
