Semiconductor circuit device having active and standby states

摘要

A P channel MOS transistor and an N channel MOS transistor turned on/off in response to an input signal in an active state as well as an N channel MOS transistor connected between an output node and the N channel MOS transistor and turned on/off in response to a control signal are provided. The input signal is at the L level in a standby state. The control signal is at the L level in the standby state and at the H level in the active state. This suppresses the effect of hot carriers in the active state and decreases a subthreshold current in the standby state.
