Abstract
PURPOSE: To make it possible to output a stable logical level with preventing the increment of power consumption dependent upon input levels by applying control signals so that the output may be obtained synchronously with input informaton.
CONSTITUTION: Input terminal 1 of inverter circuit 10 and output terminal 3' of input switch KI have the drain or suce electrode of P-chFETQP4 connected; and at the period when control signals S is applied to the gate, QP4 is turned on and input information can be obtained from output terminal 2 of circuit 10. Meanwhile, at the period when signal S is not applied to the gate, QP4 is turned off and input informaton is inhibited from being taken out. Then, the current across QP4 and N- chFETQN3 does not flow. As a result, average power consumption can be reduced.
